WEBVTT 00:08.940 --> 00:14.040 Okay, I'm still connecting with the network, but in the meantime we 00:14.040 --> 00:19.260 can have a look at the slides for today. 00:19.700 --> 00:24.620 I will upload these slides afterwards to the Ilias server. 00:27.180 --> 00:36.100 So the overview of the curriculum for this semester, or for all your 00:36.100 --> 00:39.200 mechanical design semesters, looks like that. 00:39.500 --> 00:44.260 In the last semester we have had the PDM basic sketches and basic 00:44.260 --> 00:46.460 drawings and basic features. 00:47.260 --> 00:54.860 And also we have already started with the engineering features here, 00:55.300 --> 00:57.640 which is part of MD3. 00:58.280 --> 01:01.600 So we are already in the bottom-up assembly topic. 01:03.240 --> 01:08.040 So we have some time left on that. 01:08.800 --> 01:14.840 We can really concentrate on assemblies, both types, bottom-up and top 01:14.840 --> 01:15.080 -down. 01:15.160 --> 01:16.200 I will explain what it means. 01:17.920 --> 01:21.960 And whenever there is a question about anything we have done in the 01:21.960 --> 01:25.660 past, we can discuss that and solve that. 01:27.920 --> 01:33.400 So in the next semester we will only repeat and make advanced features 01:33.400 --> 01:37.220 and advanced mechanism and stuff like that, animation. 01:38.780 --> 01:44.300 If you want to repeat anything from the past semesters, there is the 01:44.300 --> 01:45.740 screencasts. 01:48.140 --> 01:51.440 Screencasts are still only in German, but they are really click-by 01:51.440 --> 01:54.280 -click and with short comments. 01:54.580 --> 01:59.540 So I think it's really possible to follow that, even with little 01:59.540 --> 02:00.900 German knowledge. 02:01.100 --> 02:03.220 It really shows what happens, so you can follow that anyway. 02:04.960 --> 02:13.120 And we have created and are still creating screencasts about 02:13.120 --> 02:14.060 assemblies. 02:15.460 --> 02:19.960 So bottom-up, basics, advanced and so on is already available. 02:20.920 --> 02:24.600 And new screencasts are permanently created and added. 02:26.800 --> 02:33.500 In opposite to the past where the screencasts only were available via 02:33.500 --> 02:39.500 the PDM system, so you had to download a zip file, extracts and so on, 02:39.560 --> 02:43.020 in order to access the Flash movie, we have changed that. 02:43.580 --> 02:51.560 So please go on to our new webpage, which is noted here, IPEC-KIT-EDU. 02:52.280 --> 02:56.080 And since the navigation is not complete yet and it's quite 02:56.080 --> 03:02.540 cumbersome, I'm not happy with that, just type directly 124PHP and 03:02.540 --> 03:05.780 then you are directly on the start page for CAD. 03:06.380 --> 03:11.780 And you can access the Flash movies in your browser and there is links 03:11.780 --> 03:13.640 to all the other stuff. 03:14.020 --> 03:16.760 And FAQ is available again and news is available. 03:17.740 --> 03:18.080 All that. 03:21.440 --> 03:22.160 Okay. 03:24.600 --> 03:29.920 I will see if my network is up and running. 03:31.060 --> 03:33.780 Maybe I can directly show the new webpage. 04:24.320 --> 04:25.280 Okay. 05:18.860 --> 05:22.220 It's quite slow, so we don't wait for the webpage. 05:22.480 --> 05:25.040 Maybe it pops up, maybe not. 05:26.960 --> 05:29.120 Obviously even my PowerPoint is hanging. 05:30.800 --> 05:31.360 Oh, my God. 05:35.780 --> 05:35.960 Yeah. 05:39.440 --> 05:40.440 Sorry for that. 05:43.140 --> 05:43.400 Okay. 05:43.400 --> 05:44.760 At least my Pro-E is running. 05:47.040 --> 05:47.680 That's good. 05:48.740 --> 05:52.040 But what we see is that I'm offline. 05:52.720 --> 05:56.200 There is the small cabinet. 06:00.180 --> 06:01.160 Yeah. 06:16.140 --> 06:19.780 Let me tell a few words about that. 06:21.280 --> 06:25.720 There is Wildfire 5 available right now as student version. 06:27.060 --> 06:35.140 And with the Wildfire 5, they have renamed Pro-E into Creo. 06:36.180 --> 06:37.680 That's a new name. 06:39.100 --> 06:39.880 Okay. 06:40.280 --> 06:42.280 It's up to them to rename their products. 06:43.120 --> 06:48.060 Pro-E is in future Creo slash Pro. 06:48.740 --> 06:50.540 And there is another product of PTC. 06:50.880 --> 06:51.780 It's CoCreate. 06:52.000 --> 06:54.280 I think that's Creo slash direct. 06:55.380 --> 06:59.200 And the product viewer is Creo slash view, I guess. 07:00.880 --> 07:04.320 But in the end, Pro-E is still Pro-E and it works like Pro-E and they 07:04.320 --> 07:07.720 have not changed the Pro-E interface and so on. 07:07.760 --> 07:11.680 That's a new strategy and they will integrate different techniques 07:11.680 --> 07:13.240 with that Creo approach. 07:13.860 --> 07:17.020 But for us, and that's really, really important. 07:17.760 --> 07:21.160 Please, everyone attend that very important note. 07:22.000 --> 07:24.860 We use Wildfire 4, not 5. 07:26.000 --> 07:31.740 As soon as you use 5, you cannot interchange your parts anymore with 07:31.740 --> 07:32.260 your team. 07:32.840 --> 07:35.100 And there is no way to go back. 07:35.820 --> 07:40.760 And in case you work with 5 and you have items in 5 prepared for your 07:40.760 --> 07:44.860 workshop and you want to assemble your product, you're screwed. 07:46.540 --> 07:48.000 So, remain with 4. 07:48.280 --> 07:49.480 And you can still download 4. 07:49.560 --> 07:52.220 If you have problems with your installation and with your setup, you 07:52.220 --> 07:54.160 can still download Wildfire 4. 07:54.440 --> 07:56.140 It's on the same download page. 07:57.120 --> 07:59.740 I think you have to scroll a little bit down and then you will find 07:59.740 --> 08:02.160 Wildfire 4 besides Wildfire 5. 08:02.640 --> 08:02.720 Okay. 08:04.620 --> 08:06.460 Back to the webpage. 08:06.800 --> 08:10.600 That was my last click on the screen. 08:11.420 --> 08:20.540 Here we have the Lehrmaterialien and you can find the screencasts like 08:20.540 --> 08:23.980 Basics, for example, Open Pro-E. 08:25.180 --> 08:27.640 And then the Flash Movie is directly running on the webpage. 08:27.640 --> 08:30.180 I think that's a good improvement. 08:31.280 --> 08:35.960 Another improvement, you see it all the time, is that mouse icon. 08:37.320 --> 08:40.860 And you can really see what I click, like left, right, mouse button, 08:41.220 --> 08:47.480 scroll bar, scroll wheel, and even the control keys and so on. 08:47.940 --> 08:52.500 So, I hope that helps you a little bit better while I go through the 08:52.500 --> 08:53.900 screen and click stuff. 08:54.100 --> 08:54.700 There's a question. 09:03.030 --> 09:07.650 There is a difference between the screencasts and the tutorial movies. 09:08.090 --> 09:12.490 So, the screencasts are all on the webpage and the tutorial movies, 09:12.830 --> 09:17.050 which I record right now, they will be available on Diva. 09:18.030 --> 09:22.370 So, the German one of last Thursday is already available. 09:23.290 --> 09:26.630 And today's screencast will be available by end of the week. 09:27.930 --> 09:29.070 Tutorial movie, sorry. 09:32.310 --> 09:32.990 Okay. 09:32.990 --> 09:37.910 I will stop that and go back to the slides. 09:38.850 --> 09:43.530 So, what are we going to do today? 09:43.810 --> 09:52.310 We will talk about bottom-up assemblies, which is, in fact, a 09:52.310 --> 09:57.510 situation where you have prepared many parts in ProE, just like Lego. 09:59.950 --> 10:02.930 You have a part and put it together with another part. 10:03.210 --> 10:03.950 That's pretty simple. 10:04.070 --> 10:07.990 That's pretty much what happens in an assembly line in industry 10:07.990 --> 10:08.990 environments. 10:09.550 --> 10:13.850 They take given parts, screws, prepared parts, and put them together. 10:14.030 --> 10:17.110 And in the end, they have the product package and sell. 10:17.850 --> 10:22.590 And we will have a very similar situation in ProE. 10:22.590 --> 10:27.750 We have prepared parts that can be contributed by yourself, by your 10:27.750 --> 10:28.090 team. 10:29.510 --> 10:31.610 And then you assemble them together. 10:31.730 --> 10:32.830 That's bottom-up assembly. 10:33.990 --> 10:36.170 Why do we call it bottom-up assembly? 10:36.650 --> 10:38.730 Because there is two types of assemblies. 10:40.150 --> 10:44.370 The bottom-up approach is really block by block. 10:44.570 --> 10:47.150 You build your tower block by block. 10:47.150 --> 10:51.210 And the other way around is called top-down assembly. 10:51.370 --> 10:53.030 We will learn that by the end of the semester. 10:53.750 --> 10:56.550 And that's a much more advanced approach. 10:56.810 --> 11:00.210 It's a good idea to learn bottom-up first and top-down later. 11:00.770 --> 11:07.810 And in top-down, you assume, for example, we have an axis of our car. 11:08.090 --> 11:09.450 Front axis, rear axis. 11:09.690 --> 11:11.730 So there is no wheels available yet. 11:12.390 --> 11:17.670 No parts of your suspension available yet. 11:17.790 --> 11:23.590 But you know we have a distance of two axes and a height over the 11:23.590 --> 11:25.310 floor and so on. 11:25.350 --> 11:28.150 And maybe you already know that you have a symmetry of your car. 11:29.110 --> 11:35.430 And then you can start building parts right at the have to work later. 11:36.010 --> 11:41.130 So you don't put parts together, but you really shape your parts at 11:41.130 --> 11:43.150 the place where they are required. 11:44.470 --> 11:46.190 That's my disco mouse. 11:49.160 --> 11:49.940 Okay. 11:50.580 --> 11:56.420 But still, we can create new parts in assembly context and use part 11:56.420 --> 11:56.980 contours. 11:57.100 --> 12:00.520 That's, again, something we will learn now. 12:01.600 --> 12:04.620 We can add assembly features. 12:05.480 --> 12:07.680 Do you have an idea what assembly feature could be? 12:09.020 --> 12:12.760 In opposite to a ordinary part feature? 12:14.400 --> 12:15.400 No idea? 12:20.540 --> 12:28.000 The name or the feature type is... I will close the window. 12:28.580 --> 12:32.900 The feature is something you apply to 12:36.920 --> 12:38.120 given geometry. 12:38.360 --> 12:40.220 So you have a geometry that's already a feature. 12:40.460 --> 12:44.020 And then you add another geometry or you cut or you make a hole or you 12:44.020 --> 12:45.520 make chamfer rounds and so on. 12:46.800 --> 12:50.720 That's pretty common for a single part. 12:52.020 --> 12:55.800 But you can also have features like that in an assembly. 12:55.800 --> 12:59.540 You don't have creation features in an assembly. 12:59.700 --> 13:04.520 So you don't create a geometry in assembly context. 13:05.160 --> 13:07.880 But you can cut, for example, in assembly context. 13:08.340 --> 13:11.540 That's a good idea if you have many parts put together and then take 13:11.540 --> 13:15.120 your mill and make it flat all together. 13:15.140 --> 13:19.280 Or you have two parts and you make one hole through both at the same 13:19.280 --> 13:19.660 time. 13:19.820 --> 13:24.820 And these changes are also then transferred to a normal part? 13:25.200 --> 13:25.840 No, they are not. 13:25.940 --> 13:26.560 That's the difference. 13:27.000 --> 13:27.700 No, they are not. 13:28.000 --> 13:29.680 Because then you can make two drawings. 13:29.940 --> 13:34.160 One drawing of your single part without hole and then a drawing of 13:34.160 --> 13:35.920 both parts and they contain the hole. 13:36.560 --> 13:41.020 And then you know already for your production process, okay, prepare 13:41.020 --> 13:46.940 the untouched part and then drill it later on. 13:47.980 --> 13:49.720 Okay, that's assembly features. 13:51.620 --> 13:55.520 We will talk about the IPEG library a little bit. 13:55.660 --> 14:00.180 So where you can access standard parts like screws. 14:01.860 --> 14:08.140 And we will have a look in the available internet libraries like trace 14:08.140 --> 14:11.180 parts or medias and so on. 14:11.680 --> 14:16.440 And we will discuss a little bit our cut content in the mechanical 14:16.440 --> 14:17.800 design task formulation. 14:19.920 --> 14:23.240 Okay, is there a question so far? 14:26.500 --> 14:32.780 For today's example, we have prepared not only the example, but also 14:32.780 --> 14:34.460 another task sheet for you. 14:35.060 --> 14:36.880 It's really free. 14:38.200 --> 14:40.180 It's up to you to make it or not. 14:41.400 --> 14:49.340 I think it's helpful to have a little task to follow in order to learn 14:49.340 --> 14:49.680 better. 14:50.200 --> 14:53.120 Let's open that clamping device example. 15:01.600 --> 15:03.900 It's also uploaded at the 15:07.480 --> 15:14.960 PDM server and as well at the Ilias. 15:16.620 --> 15:17.960 Okay, it's a PDF. 15:19.680 --> 15:28.660 And so our goal is to make that clamping device. 15:29.040 --> 15:40.260 So we have given parts like the prism, the clamp, and that screw here 15:40.260 --> 15:43.040 and the handle right here. 15:43.780 --> 15:46.560 And there is a in red, there is a shaft. 15:47.440 --> 15:53.140 The shaft is just a helper for us to learn if our clamping device 15:53.140 --> 15:56.680 works for shafts with the diameter length and so on. 15:56.940 --> 16:01.220 So it's not really part of the assembly, but it's a testing part. 16:02.180 --> 16:07.600 Okay, we have these parts prepared. 16:09.100 --> 16:14.660 You can build them on yourself with that drawing here. 16:14.760 --> 16:17.760 That's really a quick job. 16:18.780 --> 16:23.380 But in order to save time here, I will reuse given parts. 16:24.900 --> 16:28.020 Okay, let's switch over to ProE. 16:29.540 --> 16:35.980 I started to comment the grayish cabinets icon here. 16:36.240 --> 16:41.360 That means if as long as that icon here is gray, you are offline. 16:42.180 --> 16:48.840 And we can change that by accessing tools, server manager. 16:49.500 --> 16:51.940 Then we see, okay, our server is offline. 16:52.300 --> 16:56.720 Right click and remove the checkmark at work offline. 16:57.460 --> 16:58.600 Let it synchronize. 17:03.970 --> 17:05.970 Let it synchronize. 17:08.130 --> 17:10.410 And then we can start working. 17:11.490 --> 17:14.090 So for synchronizing, it still takes time. 17:15.230 --> 17:16.670 We'll go back to the slide. 17:17.470 --> 17:20.630 What we will learn for assemblies is placement types. 17:20.970 --> 17:22.610 How can we put parts together? 17:24.050 --> 17:29.590 Of course, we can say we have two working surfaces and put these 17:29.590 --> 17:30.350 surfaces together. 17:30.450 --> 17:32.170 Then we have one constraint. 17:32.950 --> 17:38.530 We can still move our part along that connection. 17:39.110 --> 17:45.810 So we need a few other additional constraints in order to fully 100% 17:45.810 --> 17:46.870 place that part. 17:47.070 --> 17:54.950 We can also over constrain it when we have similar redundant 17:54.950 --> 17:58.810 constraints. 17:59.530 --> 18:05.350 And in both situations, under constraint and over constraint, ProE 18:05.350 --> 18:14.490 will notice that the assembly is not defined well and will warn us. 18:14.790 --> 18:18.590 So we really have to place our components inside our assembly 18:19.450 --> 18:20.050 correctly. 18:20.290 --> 18:21.370 And that's a good thing. 18:21.910 --> 18:25.750 In other CAD softwares, you have more degrees of freedom. 18:25.830 --> 18:29.250 You can place your parts more freely somewhere. 18:31.590 --> 18:35.690 That is okay in order to quickly set up your assembly, but it's maybe 18:35.690 --> 18:38.270 hard to control your assembly afterwards. 18:39.850 --> 18:40.890 Okay, let's see. 18:41.930 --> 18:43.250 Still synchronizing. 18:46.250 --> 18:55.030 We can place parts and we can also create new components. 18:57.220 --> 19:01.430 Even in the bottom-up assembly, it's still not top-down. 19:02.270 --> 19:04.390 Top-down is really a different thing. 19:05.160 --> 19:08.270 But in bottom-up assemblies, we can create parts. 19:08.650 --> 19:15.650 In that case, we make an assembly of empty standard templates and fill 19:15.650 --> 19:17.390 them with some geometry. 19:19.030 --> 19:25.670 That is a good idea in order to really make parts dependent from each 19:25.670 --> 19:25.910 other. 19:26.230 --> 19:30.930 For example, a flange, you can have one flange part dependent of the 19:30.930 --> 19:31.810 other flange part. 19:32.230 --> 19:36.830 And then when one flange side is growing, the other side will grow as 19:36.830 --> 19:37.070 well. 19:37.710 --> 19:41.390 So you don't have to control two parts, but make one part dependent 19:41.390 --> 19:43.670 from the other part and then control only one part. 19:45.950 --> 19:48.610 Okay, so we are online. 19:48.730 --> 19:49.770 It's all synchronized. 19:51.910 --> 19:53.110 We'll close this one. 19:53.250 --> 19:54.790 We see the icon is yellow. 19:55.350 --> 19:55.630 Access. 19:58.760 --> 20:04.020 Not to the uberding, but I can make the prism parts available on the 20:04.020 --> 20:04.420 library. 20:08.920 --> 20:11.920 So if I don't forget it, maybe you can remind me later. 20:12.560 --> 20:14.620 I will make them accessible for you as well. 20:14.740 --> 20:17.680 So you don't have to build them, but really use them directly for 20:17.680 --> 20:18.560 assembly. 20:19.460 --> 20:23.300 Okay, let's start with the assembly. 20:23.540 --> 20:26.960 It's a new model in our ProE. 20:27.060 --> 20:31.420 So we go on the new button. 20:31.760 --> 20:36.180 But in opposite to the past, we switch to assembly, a new assembly. 20:37.260 --> 20:41.760 And that's clamp device. 20:45.760 --> 20:51.180 And okay, it will ask for a template for bottom up. 20:51.660 --> 20:54.640 Please use that bottom up template. 20:58.330 --> 21:05.160 And then we have something looking very similar to a part, but it's an 21:05.160 --> 21:05.560 assembly. 21:05.560 --> 21:13.480 Now, you see that with the icon, there is an idea of two parts put 21:13.480 --> 21:13.860 together. 21:14.520 --> 21:19.300 Okay, so that's the container where we can put our parts in. 21:19.880 --> 21:25.360 And that assembly does not save any geometry information of any parts, 21:25.680 --> 21:31.040 but only the position and the status of the assembled components. 21:31.620 --> 21:36.040 So if you look at the file size of an assembly, it's a very small 21:36.040 --> 21:36.480 file. 21:37.780 --> 21:42.020 The parts can be very complicated, just huge, but the assembly does 21:42.020 --> 21:43.540 not save the parts themselves. 21:44.980 --> 21:48.580 Okay, let's add our first component. 21:48.940 --> 21:55.240 I think if you look at the prism, it's a good idea to start with that 21:55.240 --> 21:59.960 prism part or component first. 22:00.560 --> 22:03.480 Okay, let's go to that button. 22:04.960 --> 22:07.940 It says add component to the assembly. 22:12.190 --> 22:18.990 And I have a few parts already in my workspace. 22:20.790 --> 22:24.870 Maybe it's a good idea to make that first. 22:25.410 --> 22:28.810 Put parts that you will assemble that are available into your 22:28.810 --> 22:29.170 workspace. 22:29.510 --> 22:32.750 Maybe even check them out, but you don't need to check out parts in 22:32.750 --> 22:33.630 order to assemble them. 22:33.930 --> 22:36.270 Only have to check out your assembly. 22:36.870 --> 22:41.070 But if you really want to make sure that you are working on the 22:41.070 --> 22:42.950 assembly and nobody else, check them out. 22:44.010 --> 22:48.950 Okay, since there is only numbers, let's switch to the detail view. 22:50.790 --> 22:56.410 And here's the prism that we will assemble first. 22:57.430 --> 23:03.610 Okay, you can see the GUI changes a little bit. 23:03.670 --> 23:08.610 We have a new dashboard and we have the prism attached to our mouse 23:08.610 --> 23:08.970 pointer. 23:09.830 --> 23:18.590 The idea is to roughly position the prism somewhere where it's easy 23:18.590 --> 23:26.390 for you to find and pick your constraints. 23:27.370 --> 23:34.510 So maybe don't put it like this, where it is hard to pick either 23:34.510 --> 23:37.750 component planes or assembly planes. 23:37.910 --> 23:43.470 It's better to put it a little bit besides and to have free access to 23:43.470 --> 23:45.430 all planes and surfaces. 23:46.030 --> 23:48.710 Okay, that's only our working state now. 23:49.550 --> 23:55.330 The next thing is to define our placement constraints. 23:55.890 --> 24:04.310 I click on placement and now we can pick our constraints. 24:04.310 --> 24:11.370 Always repeating component reference, assembly reference, next 24:11.370 --> 24:14.830 component reference, next assembly reference and so on. 24:15.290 --> 24:19.550 Typically we have three constraints. 24:21.130 --> 24:23.550 Okay, let's start with the simplest. 24:25.490 --> 24:29.650 It's plane on plane. 24:31.070 --> 24:36.550 Then it says do you want to have an offset or coincident, coincident 24:36.550 --> 24:38.510 and so on. 24:38.690 --> 24:49.430 Like this one and this one or this one and this one. 24:49.710 --> 24:50.910 Okay, now it's fully constrained. 24:51.050 --> 24:53.070 The status says it's fully constrained. 24:53.930 --> 24:55.030 That's pretty simple. 24:55.750 --> 25:02.850 For our first part I recommend not to work with the planes but with 25:02.850 --> 25:04.650 coordinate systems. 25:04.810 --> 25:05.370 It's easier. 25:06.170 --> 25:14.010 So I will delete what I have made so far and change my constraint type 25:14.010 --> 25:18.130 just to default and now it's fully constrained. 25:18.890 --> 25:22.130 That means our first component has a coordinate system. 25:22.250 --> 25:25.150 Every component has a coordinate system and with the default 25:25.150 --> 25:32.330 constraint type we put our component coordinate system just coincident 25:32.330 --> 25:35.910 with the world or assembly coordinate system. 25:36.130 --> 25:38.430 For the first part that's absolutely okay. 25:41.490 --> 25:42.910 Clicking on the check mark. 25:43.750 --> 25:45.230 Now we have the new situation. 25:46.570 --> 25:49.890 We have our prism inside and we see it on the model tree. 25:50.470 --> 25:53.830 There is a new entry on the model tree. 25:54.750 --> 25:56.950 Okay, next component. 25:57.690 --> 25:59.210 The next component is the clamp. 26:00.530 --> 26:02.370 Again the assembly button. 26:04.810 --> 26:06.170 Looking for the clamp. 26:06.790 --> 26:12.310 If it is not in the workspace you can browse the cabinets 26:18.350 --> 26:22.710 like libraries for example and so on but I will remain on the 26:22.710 --> 26:23.010 workspace. 26:23.230 --> 26:26.930 That's a little faster right now and go to the clamp. 26:29.950 --> 26:30.470 Open. 26:31.130 --> 26:34.350 Okay, now we have the same starting situation. 26:34.770 --> 26:38.570 I will place it somewhere here and then we will have a look at the 26:38.570 --> 26:48.890 task sheet where we can see that we have a working surface pair right 26:48.890 --> 26:53.750 here and then it's logical to use these both surfaces for our assembly 26:53.750 --> 26:58.550 but on the other hand we see that our clamp is positioned somewhere 26:58.550 --> 27:05.050 somehow symmetrical in that direction, in that view direction here and 27:05.050 --> 27:07.750 also in the other view direction. 27:07.850 --> 27:09.490 Let me see if I have it. 27:09.970 --> 27:09.970 No. 27:11.350 --> 27:14.130 Okay but I think it's clear that we have it in the middle in both 27:14.130 --> 27:14.770 views. 27:16.170 --> 27:23.890 Okay, so selecting these surface pairs, working surface pairs is easy. 27:24.590 --> 27:33.110 I pick this one first then I can rotate my assembly and pick my 27:33.110 --> 27:36.290 corresponding working surface here. 27:37.270 --> 27:39.510 And then I say okay I don't want to have an offset. 27:40.910 --> 27:46.530 I want to have both working surface pairs really matching. 27:48.270 --> 27:51.450 Okay, new constraint is one symmetry. 27:53.150 --> 27:59.490 That plane as the component symmetry plane and then we pick the 27:59.490 --> 28:04.850 assembly symmetry plane and again we say we want to have it coincident 28:05.570 --> 28:08.750 and the same thing here. 28:08.950 --> 28:10.310 This and this coincident. 28:10.530 --> 28:14.150 Okay, now our clamp is fully constrained. 28:15.770 --> 28:17.810 It says fully constrained. 28:25.750 --> 28:28.430 Okay, so now we see our assembly. 28:28.590 --> 28:30.750 It's all in gray. 28:31.850 --> 28:37.150 Maybe it's a good idea to switch some colors. 28:38.510 --> 28:39.270 It's easy. 28:41.770 --> 28:46.850 Just click on that palette here. 28:48.310 --> 28:53.030 Select that you want to assign a color to a new component. 28:54.470 --> 28:58.190 Maybe a yellow color. 28:58.490 --> 29:00.430 We have to select our component first. 29:01.690 --> 29:08.270 Okay, click on your yellow color and then click on apply and then it's 29:08.270 --> 29:09.670 you have a new color. 29:10.850 --> 29:16.970 In that color or appearance editor there is not only color properties 29:16.970 --> 29:22.730 but also like reflection and bump maps, textures and so on. 29:23.010 --> 29:24.970 You can really play around with that. 29:27.610 --> 29:28.810 For example. 29:29.390 --> 29:35.450 And in the end you can render it and put that rendered image on your 29:35.450 --> 29:36.330 powerpoint slide. 29:41.110 --> 29:45.230 Okay, is that clear so far? 29:47.090 --> 29:49.870 Okay, let's have a look at the task sheet. 29:50.130 --> 29:56.350 We see that our screw and handle is an assembly by itself. 29:57.910 --> 30:02.070 When we turn our screw the handle is also turned. 30:02.530 --> 30:05.750 So it's if you want a sub-assembly. 30:06.250 --> 30:09.330 We put one assembly into another assembly. 30:09.830 --> 30:14.970 That means we start with a new assembly and put in the screw and put 30:14.970 --> 30:16.670 in that bolt. 30:16.670 --> 30:16.970 Okay, 30:20.100 --> 30:20.720 let's make that. 30:21.220 --> 30:22.540 I will save it first. 30:24.380 --> 30:25.800 Make a new assembly. 30:30.580 --> 30:31.720 Screw down. 30:37.300 --> 30:41.160 Of course, you're absolutely free to and you can you can assemble. 30:41.940 --> 30:45.420 For example, let's say we have a component A. 30:46.420 --> 30:53.140 We can assemble that component A into our main assembly, into our sub 30:53.140 --> 30:55.420 -assembly, into another sub-assembly. 30:55.600 --> 30:57.680 It's always the same component number A. 30:58.340 --> 31:01.920 And we can use it in all assemblies, sub-assemblies at the same time. 31:15.920 --> 31:17.640 Okay, same game. 31:18.820 --> 31:19.540 Assembly. 31:21.700 --> 31:24.620 Then we have the spindle. 31:27.830 --> 31:31.250 Our placement again is standard. 31:37.280 --> 31:38.160 Constraint types. 31:38.340 --> 31:42.700 Now we can see all our constraint types since there is nothing pre 31:42.700 --> 31:43.400 -selected yet. 31:44.140 --> 31:48.800 If we click on surfaces, ProE will assume constraint types. 31:49.100 --> 31:54.640 If you have not picked any surfaces or references yet, our constraint 31:54.640 --> 31:55.500 types are free. 31:55.900 --> 31:57.400 So let's go through them a little bit. 31:58.260 --> 32:06.300 Maybe I can even try to sketch a few of them. 32:07.080 --> 32:07.500 Let me see. 32:33.030 --> 32:37.810 Okay, I cannot keep that menu open when I sketch. 32:38.110 --> 32:39.450 So let's remind that. 32:40.410 --> 32:41.050 Mating. 32:41.650 --> 32:43.670 I think it's really clear. 32:44.290 --> 32:48.970 We have two components and we select mating surfaces. 32:50.230 --> 32:52.690 We can have aligned surfaces. 32:52.910 --> 33:01.530 Then this component is turned and these surfaces look at the same 33:01.530 --> 33:02.510 direction if you want. 33:05.130 --> 33:06.010 Insert. 33:07.410 --> 33:12.870 Inserting is if you take this one for example and you have the 33:12.870 --> 33:17.790 according hole and then you can insert two cylindric surfaces. 33:18.550 --> 33:25.990 You can also take the axis for example to insert. 33:32.070 --> 33:33.110 Coordinate system. 33:41.260 --> 33:45.740 Of course it's not only possible to have coordinate systems coincident 33:45.740 --> 33:51.260 but also in an offset and turned. 33:53.120 --> 33:55.920 So maybe you have a calculated position. 33:56.220 --> 33:59.520 Maybe you calculate a position in MATLAB or Maple. 34:00.120 --> 34:03.940 Then you can use two coordinate systems in order to offset your 34:03.940 --> 34:04.420 component. 34:06.500 --> 34:06.940 Tangent. 34:07.700 --> 34:11.080 Also pretty clear but one comment on that. 34:11.820 --> 34:20.580 If you have a surface and that's cylindrical and we have that 34:20.580 --> 34:29.000 placement of tangential contact, it can be could be problematic. 34:29.800 --> 34:35.220 For example if that surface is changed later on, smaller and smaller 34:35.220 --> 34:39.760 and smaller and smaller, that could be when you tune your complete 34:39.760 --> 34:49.600 assembly and then maybe your constraint loses its definition. 34:51.500 --> 34:55.600 So be careful please with the tangent placement. 34:59.060 --> 35:04.560 Point on line is clear, point on surface, edge on surface and so on is 35:04.560 --> 35:05.120 all clear. 35:05.480 --> 35:07.440 One special thing is fixed. 35:08.520 --> 35:16.340 In opposite to default where our coordinate systems are coincident, in 35:16.340 --> 35:23.040 the fixed constraint our component is just fixed at the place it is 35:23.040 --> 35:23.600 right now. 35:24.180 --> 35:29.180 That's very practical if you want to pre-assemble something just 35:29.180 --> 35:33.400 roughly without any constraints between parts. 35:33.660 --> 35:38.380 Just roughly position your part, click fix and then later you can 35:38.380 --> 35:41.660 maybe use proper constraints. 35:41.840 --> 35:45.300 Or maybe you are missing a constraint, you are missing a plane and you 35:45.300 --> 35:51.220 can click fix first, leave it and you have pre-assembled that part and 35:51.220 --> 35:57.240 add your datum plane later on and then use it in order to pick the 35:57.240 --> 35:59.840 correct constraints. 36:00.920 --> 36:06.860 How can you move your component in your assembly? 36:08.780 --> 36:13.580 It's not only possible right after clicking your assembly button, but 36:13.580 --> 36:20.660 also later on if you select, let me see, control and alt and then 36:20.660 --> 36:27.440 middle mouse button and you can rotate your component relative to your 36:27.440 --> 36:28.180 assembly. 36:29.800 --> 36:35.600 Right mouse button you can pan and that's it basically. 36:37.100 --> 36:38.160 Pan and rotate. 36:38.620 --> 36:39.220 That should be enough. 36:39.300 --> 36:42.900 You can reorient and then just like that. 36:44.440 --> 36:46.760 And then you could select fix for example. 36:47.440 --> 36:51.800 But in this case it's our first part in our new assembly, so our 36:51.800 --> 36:53.480 constraint type is default again. 36:54.880 --> 37:01.340 We pick our green checkmark and it's all set so far. 37:01.480 --> 37:04.640 Okay, now our handle is missing. 37:06.100 --> 37:13.940 That handle is a standard part bolt and you can pick that from the 37:13.940 --> 37:14.300 library. 37:18.040 --> 37:25.900 And in case we just use standard parts that we don't want to change in 37:25.900 --> 37:32.600 any way, we can just pick parts from the library and assemble them and 37:32.600 --> 37:33.140 forget it. 37:33.860 --> 37:40.400 The assembly will remember, will memorize the position and the path of 37:40.400 --> 37:45.200 that part and will always find that bolt. 37:46.220 --> 37:49.620 There is no need for that part to be in your common space. 37:50.120 --> 37:53.780 It will be in your workspace of course, but not in your common space. 37:54.100 --> 37:59.320 If you want to modify that part first, maybe pick a screw and then 37:59.320 --> 38:04.160 make some additional features like an additional hole for example into 38:04.160 --> 38:09.580 a standard screw, you have to copy first that screw into your common 38:09.580 --> 38:09.960 space. 38:10.040 --> 38:10.620 I will show it. 38:11.100 --> 38:15.260 But first we just pick a part, assemble it and forget it. 38:17.300 --> 38:20.080 Okay, same order. 38:21.940 --> 38:24.140 But we will browse our cabinets, 38:30.570 --> 38:37.230 browse the libraries, Bibliotheken and now I can see, since I am the 38:37.230 --> 38:40.270 admin, I can see two NormTile libraries. 38:41.230 --> 38:43.970 But you only see one and that's the correct one. 38:44.170 --> 38:46.610 So I have to check which one is the correct one. 38:48.290 --> 38:50.650 Ah yeah, that's it. 38:51.010 --> 38:56.970 Okay, Zylinderstift, bolt and I pick my part here prepared. 38:57.150 --> 38:59.890 That's the single part right now. 39:00.130 --> 39:06.350 In that library it's easier to browse. 39:07.290 --> 39:08.290 Okay and open. 39:09.370 --> 39:13.730 Okay in here, same thing, just roughly place it. 39:15.410 --> 39:20.330 And now we will pick as the constraint type an insert constraint. 39:21.570 --> 39:26.130 Pick the cylindrical surface of that part and pick the cylindrical 39:26.130 --> 39:27.290 surface of that part. 39:28.410 --> 39:37.210 Okay and the next constraint is this one and this one in a symmetrical 39:37.210 --> 39:37.870 condition. 39:39.290 --> 39:40.090 Was there a question? 39:41.450 --> 39:44.030 Okay and now let's look at the status. 39:44.570 --> 39:50.050 We have two constraints but our status is already fully constrained 39:50.050 --> 39:56.610 and that's because we can allow assumptions from ProE. 39:57.530 --> 40:04.270 That means when we assemble cylindrical parts into each other, the 40:05.390 --> 40:09.410 angular position of that cylindrical part doesn't matter. 40:09.770 --> 40:13.490 ProE can assume any angular position. 40:13.850 --> 40:19.490 So we can save time by leaving it to ProE to assume that. 40:20.150 --> 40:24.850 If it is important for us to have an angular position, we can remove 40:24.850 --> 40:32.070 that check mark and say okay for example this plane and this one 40:32.070 --> 40:40.430 should be oriented of course as an additional constraint. 40:44.480 --> 40:47.000 This one and this one. 40:47.040 --> 40:52.140 So now we have three constraints and then it's fully constrained 40:52.140 --> 40:52.540 again. 40:53.300 --> 41:00.800 If I remove the angular orientation, I have to pick the allow 41:00.800 --> 41:03.600 assumptions and then it's fully constrained again. 41:03.760 --> 41:09.720 So please notice that or remember that because it really saves time if 41:09.720 --> 41:12.400 you assemble screws, shafts and so on. 41:12.420 --> 41:18.060 Just click it and with two constraints and then it's fully 41:18.060 --> 41:18.520 constrained. 41:19.000 --> 41:26.540 Okay let's use the check mark and save our assembly. 41:29.160 --> 41:36.400 Okay, if we have colored parts in our assembly, 41:41.480 --> 41:43.940 let me show it with an example. 41:45.840 --> 41:51.040 Let's color this part here inside of our assembly, just the whole 41:51.040 --> 41:51.500 assembly. 41:52.260 --> 41:58.480 Say you want to have a blue assembly, then everything gets blue. 41:59.560 --> 42:03.280 If we assemble that to our clamping device, it's blue. 42:03.800 --> 42:06.160 But we can recolor it in our 42:09.800 --> 42:13.620 clamping device assembly, but that still remains blue. 42:14.760 --> 42:20.880 For example, if I open the bolt it's gray. 42:22.060 --> 42:23.480 It's only blue in the assembly. 42:24.220 --> 42:29.140 And that's a good idea because the gray color is a good color to work 42:29.140 --> 42:29.760 with geometry. 42:30.200 --> 42:35.560 You have always the correct contrast in the sketch here inside of your 42:35.560 --> 42:36.340 3D view. 42:39.420 --> 42:43.720 But in the assembly maybe it's better to have different colors. 42:44.340 --> 42:50.660 So always prefer to color your parts in the assembly rather than 42:50.660 --> 42:54.180 coloring them in component state. 43:09.470 --> 43:17.150 The question was to make one part out of a given assembly with several 43:17.150 --> 43:17.690 parts. 43:22.370 --> 43:28.810 Yeah, it is possible, but I don't recommend it for the reason you 43:28.810 --> 43:29.530 mentioned. 43:30.030 --> 43:34.810 If you want to have it glued or welded, you still have two parts. 43:35.630 --> 43:40.690 You still would have your two parts manufactured and then put them 43:40.690 --> 43:43.990 together and then add the weld afterwards as a feature. 43:44.430 --> 43:45.490 That's possible in ProE. 43:45.590 --> 43:47.850 Maybe I can show that to you if you have time left. 43:48.610 --> 43:52.810 Or you can make a note and say, okay, I want to have it glued here. 43:53.870 --> 44:01.030 But of course there is a reason for creating a single part out of an 44:01.030 --> 44:01.370 assembly. 44:01.810 --> 44:05.110 For example, if you want to have it rapid prototyped. 44:06.050 --> 44:09.410 So you have your assembly and then you make one plastic part with 44:09.410 --> 44:10.230 rapid prototyping. 44:10.330 --> 44:15.850 Your rapid prototyping service will ask you to provide one block. 44:16.550 --> 44:19.290 Then you can make one thing out of many things. 44:19.930 --> 44:23.790 Or if you want to make, for example, a package 44:28.050 --> 44:29.090 like Styrofoam. 44:29.450 --> 44:31.350 Is there an English word for Styrofoam? 44:40.050 --> 44:42.290 For packaging, for example, your lap... 44:43.670 --> 44:44.190 Styrofoam. 44:44.610 --> 44:45.410 Yeah, Styrofoam. 44:45.850 --> 44:50.290 If you want to make, for example, a Styrofoam packaging for your 44:50.290 --> 44:57.470 product, then you need, for example, a negative form of your assembly. 44:57.910 --> 45:03.150 And then it's a good idea to make... to wrap your complete assembly. 45:03.510 --> 45:07.990 Make one negative... one positive part and then cut that one positive 45:07.990 --> 45:10.530 part out of your several Styrofoams. 45:11.010 --> 45:15.910 That's a reason, for example, to make a single part out of an 45:15.910 --> 45:16.270 assembly. 45:19.390 --> 45:22.710 And I can also show you how that works, but not today. 45:26.210 --> 45:29.710 Okay, now we have two windows open in ProE. 45:29.910 --> 45:32.490 And that's very common if you work with assemblies. 45:32.990 --> 45:34.570 You have several windows open. 45:34.750 --> 45:40.590 Of course, you can switch with the windows taskbar, but then you will 45:40.590 --> 45:42.910 see that your window is not active. 45:43.030 --> 45:43.790 It's all gray. 45:44.450 --> 45:49.450 You have that strange sign as mouse pointer and so on. 45:49.770 --> 45:53.950 If you have that situation, you can activate your current window just 45:53.950 --> 45:57.410 by clicking Ctrl and A. 45:59.230 --> 46:00.910 Ctrl A for activate. 46:01.610 --> 46:06.150 Or you just have the same situation in the other window now. 46:06.450 --> 46:09.670 You can just pick window, activate. 46:10.810 --> 46:12.190 Then it's active again. 46:13.050 --> 46:19.830 Or you can directly switch between your windows with the window menu 46:19.830 --> 46:21.530 and then it's directly activated. 46:22.290 --> 46:29.810 Talking about active parts, it's also possible to work on part level 46:29.810 --> 46:30.570 in an assembly. 46:31.110 --> 46:34.570 Then I would activate my part. 46:35.030 --> 46:41.250 For example, if I want to have a chamfer on our clamp, I can right 46:41.250 --> 46:43.810 click on our chamfer, say activate. 46:44.310 --> 46:48.710 Then we will see that green icon here. 46:49.450 --> 46:53.550 And only our clamp is opaque. 46:55.050 --> 47:00.930 Okay, then we can maybe click here, add our chamfer, 47:04.370 --> 47:06.350 like that. 47:07.530 --> 47:10.970 Okay, and then we want to return to the assembly. 47:12.470 --> 47:16.510 And many, many people forget to make that and then they continue 47:16.510 --> 47:20.030 working and they want to make something in assembly context. 47:20.270 --> 47:22.490 Then they miss, for example, our assembly button. 47:23.410 --> 47:27.530 So please make sure if you work on part context or component context 47:27.530 --> 47:33.050 in your assembly to reactivate your assembly context as soon as 47:33.050 --> 47:33.470 possible. 47:33.970 --> 47:40.990 Again, you can make control A or you can right click on your assembly 47:40.990 --> 47:41.850 and activate it. 47:42.190 --> 47:45.210 And then you are back in your assembly and you can pick your assembly 47:45.210 --> 47:45.450 button. 47:45.590 --> 47:49.710 That's powerful, but some people forget about that. 47:51.030 --> 47:52.750 Okay, let's assemble the spindle. 47:56.130 --> 47:58.570 I have called it screw down. 48:01.330 --> 48:07.050 Whenever we open a part, not a part, an assembly, whenever we open an 48:07.050 --> 48:10.890 assembly, and that's the case if we assemble a sub-assembly, then the 48:10.890 --> 48:15.630 sub -assembly is also opened first, ProE asks us about the 48:15.630 --> 48:18.750 representation of that assembly. 48:19.410 --> 48:26.590 It's possible if you imagine we have a cut assembly of our Airbus or a 48:26.590 --> 48:31.310 complete car, then it takes forever to open that assembly. 48:31.990 --> 48:37.850 Maybe we only want to know a certain position or a certain situation, 48:38.190 --> 48:44.850 then we don't need to load all geometry information into our ProE. 48:45.250 --> 48:50.650 Then we can open different representations of our assembly. 48:50.950 --> 48:56.450 But for our first steps, make sure that you always open the master 48:56.450 --> 48:57.890 representation. 48:58.870 --> 49:01.250 So don't change anything, just open. 49:03.170 --> 49:04.470 Okay. 49:06.810 --> 49:12.570 Again, our constraints type is insert. 49:13.630 --> 49:18.690 This one and this one. 49:18.990 --> 49:20.890 Let's flip it. 49:21.170 --> 49:22.110 It doesn't flip. 49:22.950 --> 49:25.790 If it doesn't flip, that happens sometimes. 49:27.090 --> 49:33.490 You can use, for example, a new constraint and say I want to have this 49:33.490 --> 49:38.190 one and this one. 49:39.590 --> 49:46.790 And now you can flip that mating constraint, move it, and then it's 49:46.790 --> 49:48.810 fully constrained since it's cylindrical. 49:50.530 --> 49:58.810 If we use our moving apart component in assembly context, Ctrl-Alt 49:58.810 --> 50:03.810 -Rotate, it rotates around that remaining degree of freedom. 50:05.810 --> 50:06.750 Okay. 50:06.830 --> 50:08.770 But still, it's assumed. 50:08.770 --> 50:09.690 Okay. 50:15.860 --> 50:20.580 Let's now create a part in assembly context. 50:21.840 --> 50:28.080 I will save it first, because we want to have that red shaft in order 50:28.080 --> 50:34.220 to check if all diameters for our shafts are possible with our 50:34.220 --> 50:35.020 clamping device. 50:37.060 --> 50:44.080 So here we have the assemble button, and one button below is the 50:44.080 --> 50:44.820 create button. 50:44.980 --> 50:45.580 That's different. 50:47.120 --> 50:51.680 Now, I want to make sure everyone understands the concept of creating 50:51.680 --> 50:53.400 a part in assembly context. 50:56.680 --> 51:01.320 If you click on that, you get a new menu, and first you have to select 51:01.320 --> 51:05.300 what type of component do you want to create in your assembly context. 51:05.900 --> 51:09.600 Very common is to make a part, so just leave it part. 51:11.040 --> 51:13.300 Our common name is shaft. 51:16.040 --> 51:21.620 And in the next step, it will ask for the template. 51:22.560 --> 51:25.820 And I really recommend that you use your standard template. 51:26.600 --> 51:34.560 You can work with empty parts or write... creating features right off, 51:35.320 --> 51:41.480 but more stable is to use the common part template. 51:44.930 --> 51:53.850 Okay, so now we are in the assembly dialogue, and we have an empty 51:53.850 --> 51:57.710 template that we can move around here. 51:58.770 --> 52:06.190 Since in the next step we will create our shaft, we can place again 52:06.190 --> 52:10.830 that template at default position. 52:12.310 --> 52:21.250 So now it's coincident, and we have a new part in our assembly 52:21.250 --> 52:24.630 positioned on world coordinate system. 52:25.430 --> 52:33.290 Now we activate our shaft, and say that we want to create an 52:33.290 --> 52:37.930 extrusion, our shaft, in that context. 52:38.930 --> 52:44.370 Okay, we need a plane for our sketch. 52:48.110 --> 52:52.230 Let me see if I... not this one, this one. 53:03.260 --> 53:03.820 Wrong. 53:05.980 --> 53:07.400 Okay, I will leave the sketch. 53:24.840 --> 53:26.540 Okay, that was the correct one. 53:27.500 --> 53:34.280 Okay, and in the next step we pick references from our prism assembly. 53:35.140 --> 53:41.700 Here's a reference, select reference button, and then we pick, for 53:41.700 --> 53:45.020 example, this and this surface. 53:46.320 --> 53:53.420 And in the next step we just sketch our shaft somewhere, and 53:59.630 --> 54:01.630 constrain it to our prism. 54:02.130 --> 54:14.830 Tangential here, tangential here, here, and maybe with some 30 54:14.830 --> 54:16.170 millimeters. 54:17.970 --> 54:26.370 Okay, and extrude it in both directions, symmetrical, an arbitrary 54:26.370 --> 54:28.610 length, and okay. 54:29.830 --> 54:35.730 So what you see now is we have the shaft, which is created at the 54:35.730 --> 54:36.990 place it should be. 54:40.050 --> 54:45.930 Okay, now let's go back to the 54:51.690 --> 54:54.070 screw and edit the definition. 54:55.210 --> 54:56.090 Ah, excuse me. 54:57.210 --> 55:02.630 I will pull up the shaft over the screw in order to have the shaft 55:02.630 --> 55:04.970 available for screw positioning. 55:05.750 --> 55:08.430 Right click, edit definition. 55:08.590 --> 55:12.550 I want to make the screw following the shaft diameter. 55:13.870 --> 55:23.650 So I will remove the mating constraint and add a new constraint, which 55:23.650 --> 55:30.710 is in that case tangential, even if I do not recommend this one. 55:32.030 --> 55:41.690 And pick our shaft surface and pick our screw working surface. 55:42.990 --> 55:52.930 Okay, then it happens that it flips again, so we go back into edit 55:52.930 --> 55:53.430 definition. 55:54.490 --> 55:59.850 And as I said, as a trick, we make a new constraint and say that we 55:59.850 --> 56:06.310 want to have this surface and maybe this surface not mating, but 56:06.310 --> 56:09.250 aligned and not coincident, but only oriented. 56:09.630 --> 56:12.990 No matter where they are, they have to show in the same direction. 56:13.810 --> 56:16.070 That's the information about oriented. 56:17.010 --> 56:18.070 So it's parallel. 56:19.830 --> 56:25.510 Okay, and now it's positioned correctly. 56:26.370 --> 56:31.990 Okay, let's now change the shaft in order to check if our function of 56:31.990 --> 56:34.370 the clamping device is fulfilled in every situation. 56:35.450 --> 56:39.310 So right click, activate. 56:40.810 --> 56:43.450 Maybe you don't even need to activate it for editing it. 56:43.770 --> 56:47.230 You can directly, should be possible to directly click on the 56:47.230 --> 56:48.830 extrusion, edit. 56:49.230 --> 56:49.550 Ah, yeah, okay. 56:50.670 --> 56:52.130 Pick the 30 millimeters. 56:52.750 --> 56:57.970 Say we want to have 60, for example, and then regenerate it. 56:58.290 --> 57:01.710 And you see everything moves and you see you have a collision. 57:03.430 --> 57:07.930 Talking about collisions, you can make analyses in assemblies if 57:07.930 --> 57:20.530 something is colliding by analysis, model global interference, and 57:20.530 --> 57:25.430 click on the glasses and then you see in red, that's the overlapping 57:25.430 --> 57:26.630 geometry. 57:26.830 --> 57:31.250 Sometimes it's interesting to know how big is my overlapping geometry. 57:32.310 --> 57:36.490 Okay, let's edit it again. 57:37.650 --> 57:45.210 Say 15, regenerate, and then we see our clamping device is working 57:45.210 --> 57:50.390 also for shafts with 15 millimeters in diameter. 57:52.550 --> 57:56.750 Okay, let's 58:06.380 --> 58:13.120 talk about the assembly features, what we have discussed before. 58:15.480 --> 58:20.040 Maybe we want a securing 58:24.060 --> 58:25.020 function. 58:25.020 --> 58:32.080 So let's say we want to have the screw locked at a certain position. 58:32.920 --> 58:35.560 How would we do that in reality? 58:36.060 --> 58:45.480 We could, for example, drill a hole right here through the clamp and 58:45.480 --> 58:50.220 through the screw itself. 58:51.860 --> 58:58.020 And in order to get that matched, we would prepare our screw and 58:58.020 --> 59:03.260 prepare our clamp without drilling any holes, put it together, search 59:03.260 --> 59:09.140 the position I want to have reproducible, put it on our drilling 59:09.140 --> 59:15.180 machine, and then drill the hole in order to have that hole available 59:15.180 --> 59:18.560 for a bolt, for example, to secure that position. 59:19.960 --> 59:23.380 That is a case where we can use assembly features. 59:24.280 --> 59:26.200 Okay, make sure that your assembly is activated. 59:28.600 --> 59:32.380 And then you can add the hole feature. 59:33.600 --> 59:43.480 Say we want to have it drilled through this surface as an offset from 59:43.480 --> 59:47.000 here and an offset from the middle. 59:49.620 --> 59:51.180 Diameter quite small. 59:54.220 --> 59:56.680 Okay, yellow on yellow, sorry for that. 59:57.980 --> 01:00:00.640 Let me switch on wireframe view. 01:00:00.640 --> 01:00:03.060 Yeah, okay. 01:00:03.780 --> 01:00:07.020 And we drill through everything. 01:00:12.460 --> 01:00:14.700 Okay, now we see what happened. 01:00:15.380 --> 01:00:19.180 Our screw is drilled and our clamp is drilled. 01:00:19.340 --> 01:00:26.480 And if we open our screw, there is no hole in the screw. 01:00:26.940 --> 01:00:29.740 So it's only active in assembly context. 01:00:29.740 --> 01:00:31.940 And that's a good idea here. 01:00:42.000 --> 01:00:44.300 Okay, is that clear for you? 01:00:49.050 --> 01:00:51.130 Let me peek on the... 01:00:59.340 --> 01:01:03.240 I think right now our assembly is finished so far. 01:01:05.580 --> 01:01:09.400 Let's talk about the model library a little bit. 01:01:11.280 --> 01:01:15.500 We have learned we can just pick parts from the library and assemble 01:01:15.500 --> 01:01:15.760 it. 01:01:15.960 --> 01:01:16.620 It's easy. 01:01:17.040 --> 01:01:20.240 If we want to modify, we have to save a copy. 01:01:20.340 --> 01:01:21.100 How can you do that? 01:01:23.440 --> 01:01:28.420 Just go... or maybe the easiest thing is to browse it in the internal 01:01:28.420 --> 01:01:29.640 browser first. 01:01:48.980 --> 01:01:52.020 There it takes loading. 01:01:55.260 --> 01:01:55.600 Okay. 01:01:56.940 --> 01:01:58.080 Libraries. 01:02:00.430 --> 01:02:01.500 For example, 01:02:05.140 --> 01:02:06.380 standard parts. 01:02:07.960 --> 01:02:10.100 Or let's say Übungsteile. 01:02:10.440 --> 01:02:16.860 That's where you can also pick the prepared parts for your Mechanical 01:02:16.860 --> 01:02:18.140 Design 3 tasksheet. 01:02:22.940 --> 01:02:24.180 And Ballenwickler. 01:02:24.360 --> 01:02:32.160 That's the assembly you are required to assemble for the first project 01:02:32.160 --> 01:02:32.500 meeting. 01:02:35.400 --> 01:02:39.080 And in order... let's assume that's a library part. 01:02:39.400 --> 01:02:43.600 In order to have it as a copy in your workspace, in your common space, 01:02:43.800 --> 01:02:46.300 just open it in ProE first. 01:02:48.900 --> 01:02:51.980 And then say... it's not active. 01:02:53.580 --> 01:02:54.100 File. 01:02:54.680 --> 01:02:55.520 Save a copy. 01:02:57.040 --> 01:03:00.000 And then you are in your workspace, Übeding. 01:03:00.660 --> 01:03:02.020 You get a new number. 01:03:02.620 --> 01:03:03.140 580. 01:03:06.540 --> 01:03:09.860 And please note that the part you have opened is still the part from 01:03:09.860 --> 01:03:10.300 the library. 01:03:10.480 --> 01:03:11.140 So close it. 01:03:11.780 --> 01:03:14.400 Or the best way would be to remove it from memory. 01:03:17.980 --> 01:03:19.720 Erase current from memory. 01:03:20.400 --> 01:03:21.280 From session. 01:03:21.760 --> 01:03:21.880 Yes. 01:03:23.020 --> 01:03:31.360 And then open 580 from your workspace. 01:03:31.660 --> 01:03:34.820 Then you have your part from the library as a copy. 01:03:35.280 --> 01:03:39.220 So it has nothing to do anymore with your library part. 01:03:40.320 --> 01:03:41.300 And now you can modify. 01:03:41.480 --> 01:03:43.920 Now you are free to check out, check in, and so on. 01:03:43.920 --> 01:03:44.200 Yeah. 01:03:46.680 --> 01:03:48.300 It has a strange name. 01:03:49.140 --> 01:03:50.560 It has only a number. 01:03:51.180 --> 01:03:52.540 Maybe you want to rename it. 01:03:55.040 --> 01:03:58.560 And so you just go into your workspace. 01:03:59.720 --> 01:04:01.080 In the browser view. 01:04:07.860 --> 01:04:09.760 Search your 580 part. 01:04:15.250 --> 01:04:15.990 This one. 01:04:16.670 --> 01:04:17.990 Go at the info button. 01:04:23.680 --> 01:04:27.840 Then you can see, okay, number, name, and file name is all the same. 01:04:27.980 --> 01:04:29.800 But we want to have a common name for that. 01:04:31.000 --> 01:04:31.440 Actions. 01:04:34.580 --> 01:04:35.020 Rename. 01:04:46.380 --> 01:04:50.260 Then you can say, for example, my shaft. 01:04:52.980 --> 01:04:56.000 A new file name. 01:04:56.460 --> 01:05:05.360 Or you can say, with that icon here, I want to have the number and the 01:05:05.360 --> 01:05:07.500 file name generated automatically. 01:05:09.820 --> 01:05:11.080 And then pick okay. 01:05:17.340 --> 01:05:22.360 And then you can see, okay, my part now has the name, my shaft, the 01:05:22.360 --> 01:05:23.520 number, and the file name. 01:05:23.940 --> 01:05:24.060 Okay. 01:05:25.160 --> 01:05:26.920 That's renaming. 01:05:29.680 --> 01:05:35.440 I think that's both situations accessing parts from the IPEC library. 01:05:35.560 --> 01:05:39.800 But there is also the situation where you want to have parts 01:05:39.800 --> 01:05:43.220 downloaded from the internet. 01:05:46.020 --> 01:05:52.520 Good starting points, for example, for bearings is the INA medias 01:05:52.520 --> 01:05:53.760 catalog. 01:05:57.220 --> 01:06:02.540 I have links directly to a certain bearing. 01:06:03.120 --> 01:06:06.080 There is the cart, shopping cart. 01:06:15.860 --> 01:06:17.220 Oh, sorry. 01:06:17.700 --> 01:06:19.440 Click on cart, on the cart symbol. 01:06:20.760 --> 01:06:20.940 Okay. 01:06:20.980 --> 01:06:22.660 And then download from TraceParts. 01:06:23.040 --> 01:06:28.100 There's a lot of manufacturers already connected in TraceParts. 01:06:29.380 --> 01:06:34.640 As the download format, please try to select STEP. 01:06:35.540 --> 01:06:38.380 Try to select STEP or IGES. 01:06:39.100 --> 01:06:45.120 All other formats, even ProE neutral format is not that good. 01:06:45.620 --> 01:06:46.900 So STEP is really the best. 01:06:48.800 --> 01:06:49.560 Yeah. 01:06:51.040 --> 01:06:51.800 Okay. 01:06:51.940 --> 01:06:52.220 STEP. 01:07:01.320 --> 01:07:01.840 Okay. 01:07:01.880 --> 01:07:03.080 And then you can download it. 01:07:08.900 --> 01:07:13.720 And let's open it with the SIP file manager. 01:07:14.600 --> 01:07:16.800 And here we can see our STEP file. 01:07:18.880 --> 01:07:21.320 First, I just extract it to my desktop. 01:07:22.280 --> 01:07:29.000 And then I just drag and drop it in my ProE window. 01:07:29.000 --> 01:07:34.270 So, if that doesn't work, 01:07:38.140 --> 01:07:40.800 let's try to open it directly from desktop. 01:07:54.480 --> 01:08:01.920 Sometimes you could rename it from STP to STEP or view all files. 01:08:04.100 --> 01:08:07.580 Let me try to rename it to STP. 01:08:23.320 --> 01:08:23.880 Strange. 01:08:24.420 --> 01:08:25.760 Ah, now we have it here. 01:08:26.660 --> 01:08:26.660 Okay. 01:08:27.780 --> 01:08:28.340 Okay. 01:08:28.380 --> 01:08:28.700 And open. 01:08:29.340 --> 01:08:33.340 And the very important... 01:08:36.530 --> 01:08:38.290 I'm missing a dialogue. 01:09:14.750 --> 01:09:15.310 Okay. 01:09:16.810 --> 01:09:19.230 That was the dialogue I missed. 01:09:19.550 --> 01:09:21.090 Somehow it wasn't background or whatever. 01:09:21.090 --> 01:09:24.090 So, typically it works just to drag and drop. 01:09:24.810 --> 01:09:26.610 Sometimes it's a little bit more complicated. 01:09:29.050 --> 01:09:29.530 Okay. 01:09:29.610 --> 01:09:36.750 We want to either append the STEP file in a given model or create a 01:09:36.750 --> 01:09:37.050 new one. 01:09:37.150 --> 01:09:39.850 I think a good idea is to create a new one. 01:09:44.100 --> 01:09:44.580 Okay. 01:09:45.360 --> 01:09:47.680 I will explain it verbally. 01:09:48.200 --> 01:09:54.460 If you create a new component from a downloaded STEP, you have a 01:09:54.460 --> 01:09:59.220 choice to create a part or an assembly. 01:10:00.340 --> 01:10:04.240 In your ball bearing, you have several parts. 01:10:05.660 --> 01:10:07.120 And it's not a good idea. 01:10:07.360 --> 01:10:08.400 Please, guys. 01:10:09.580 --> 01:10:16.920 It's not a good idea to import a ball bearing from INA as an assembly, 01:10:17.080 --> 01:10:22.980 because then you have immediately 10, 15, 20 new parts. 01:10:23.400 --> 01:10:27.960 Just balls, two rings, that's it. 01:10:28.440 --> 01:10:33.740 So, it's easier, much easier to import your ball bearing as a single 01:10:33.740 --> 01:10:34.180 part. 01:10:34.640 --> 01:10:37.820 And it's merged just the geometry. 01:10:38.220 --> 01:10:39.200 And you don't need more. 01:10:39.760 --> 01:10:43.660 For your item list, it's enough to have one part that has the name of 01:10:43.660 --> 01:10:45.140 the bearing. 01:10:45.680 --> 01:10:46.380 So, that's okay. 01:10:46.620 --> 01:10:49.580 So, don't import them as assemblies. 01:10:49.760 --> 01:10:53.200 That just trashes your workspace. 01:10:54.760 --> 01:10:55.080 Okay. 01:10:58.620 --> 01:11:02.460 And please, avoid family tables. 01:11:03.100 --> 01:11:04.440 You don't need to know what it is. 01:11:05.040 --> 01:11:09.820 But if anyone offers family tables for download in the internet for 01:11:09.820 --> 01:11:11.080 you, avoid them. 01:11:11.200 --> 01:11:14.580 Because they don't really work together with the PDM system. 01:11:15.500 --> 01:11:23.100 And then you can easily not only trash your workspace, but lock up 01:11:23.100 --> 01:11:24.440 your workspace. 01:11:24.700 --> 01:11:25.740 And that's not fun. 01:11:27.560 --> 01:11:27.820 Okay. 01:11:27.960 --> 01:11:35.040 In the remaining few minutes, let's glance over the 01:11:40.260 --> 01:11:42.060 task formulation. 01:11:45.720 --> 01:11:51.740 So, what you have to do is to assemble that wrapping unit. 01:11:53.260 --> 01:11:57.200 All parts are available in Übungsteile library. 01:11:58.700 --> 01:12:02.640 Make these copy first in your common space. 01:12:03.280 --> 01:12:11.480 Because maybe it's a good idea to modify them for the project meeting 01:12:11.480 --> 01:12:12.100 two and three. 01:12:13.260 --> 01:12:15.520 And your task is to assemble them. 01:12:16.420 --> 01:12:18.100 So, it looks like this. 01:12:19.400 --> 01:12:21.440 In detail view, like this. 01:12:22.440 --> 01:12:23.200 And like this. 01:12:24.060 --> 01:12:30.440 Again, you will have these slides available on Ilias as a PDF and see 01:12:30.440 --> 01:12:32.220 what you should assemble. 01:12:33.640 --> 01:12:34.300 Okay. 01:12:35.220 --> 01:12:43.760 So, let's quickly go through the task sheet and discuss the important 01:12:46.400 --> 01:12:47.720 CAD topics. 01:12:48.400 --> 01:12:48.620 Okay. 01:12:48.740 --> 01:12:52.300 First, comment as last semester. 01:12:53.000 --> 01:12:58.100 Make sure, please, to check in your components. 01:12:58.260 --> 01:13:00.560 Of course, you need a working product and working accounts. 01:13:00.780 --> 01:13:01.480 That's my job. 01:13:01.960 --> 01:13:08.960 But if that is working, make sure to use it. 01:13:09.960 --> 01:13:10.520 Okay. 01:13:10.920 --> 01:13:15.660 In project meeting one, again, assemble the components of the 01:13:15.660 --> 01:13:20.000 packaging mechanism, I call it wrapping unit, in ProE. 01:13:20.160 --> 01:13:20.800 That's all. 01:13:21.260 --> 01:13:23.280 I told you where you can get the parts. 01:13:23.800 --> 01:13:27.940 You can look how it looks like on the slides and then it's just 01:13:27.940 --> 01:13:29.700 assembling it and that's okay. 01:13:32.570 --> 01:13:37.950 In project meeting two, you have to create, we can discuss that in the 01:13:37.950 --> 01:13:43.550 next tutorial as well, but already we can have the big picture of the 01:13:43.550 --> 01:13:44.090 task sheet. 01:13:45.350 --> 01:13:48.330 Create a CAD drawing of your stand wheel. 01:13:50.550 --> 01:13:54.370 The important hint is not all team members have to draw all components 01:13:54.370 --> 01:13:55.590 of the stand wheel in CAD. 01:13:57.590 --> 01:14:01.650 So, make sure that before you start with your assemblies, before you 01:14:01.650 --> 01:14:07.990 start creating parts, sit together on your team and manage who should 01:14:07.990 --> 01:14:10.250 prepare what part. 01:14:10.650 --> 01:14:16.210 For example, you make the wheel, you make some spindle, you prepare 01:14:16.210 --> 01:14:20.310 the screws, you download the bearings from INA and so on. 01:14:20.310 --> 01:14:26.170 You put it all together in your common space and then in one team 01:14:26.170 --> 01:14:31.890 session, in advance to your workshop meeting, you can sit together and 01:14:31.890 --> 01:14:32.630 make your assembly. 01:14:33.110 --> 01:14:34.810 It's okay to have one assembly. 01:14:35.330 --> 01:14:39.030 Maybe you can organize it to have a few sub-assemblies so that 01:14:39.030 --> 01:14:46.010 everyone can already work with assembly stuff on his own. 01:14:46.870 --> 01:14:50.630 And then later you make your big single assembly and then it's all 01:14:50.630 --> 01:14:50.810 done. 01:14:50.910 --> 01:14:52.750 That's enough for the project meeting. 01:14:53.850 --> 01:14:57.290 And please make sure to work in the PDM system. 01:14:57.430 --> 01:15:02.310 In the next tutorial, Steffen and me will work with two computers and 01:15:02.310 --> 01:15:07.750 show you how to prepare and change assembly parts in the team in the 01:15:07.750 --> 01:15:09.630 ProE and with the PDM system. 01:15:09.730 --> 01:15:10.690 That's really neat. 01:15:11.390 --> 01:15:13.030 Okay, then there's a question. 01:15:23.820 --> 01:15:27.760 The topics for the colloquium in the next workshop, that's something I 01:15:27.760 --> 01:15:29.460 cannot tell you, unfortunately. 01:15:31.000 --> 01:15:39.200 Since CAD topics are not asked, CAD topics are only discussed together 01:15:39.200 --> 01:15:41.800 on the basis of what you did. 01:15:42.060 --> 01:15:51.000 But in the colloquium, you can orient yourself on the lessons so far, 01:15:51.160 --> 01:15:53.780 on the tutorials. 01:15:55.020 --> 01:15:58.260 I'm not sure, maybe there is a bearing tutorial and so on. 01:15:59.240 --> 01:16:03.260 And all topics of that can be part of the colloquium. 01:16:03.780 --> 01:16:05.680 So that's what I can tell you. 01:16:06.980 --> 01:16:09.700 In general, 01:16:13.360 --> 01:16:21.800 there is no need to model standard parts. 01:16:22.000 --> 01:16:24.420 That's really some stupid job. 01:16:24.880 --> 01:16:30.420 So if you have the possibility to grab standard parts somewhere, just 01:16:30.420 --> 01:16:30.940 do it. 01:16:31.220 --> 01:16:34.980 Make sure that they are properly managed in your PDM system. 01:16:35.320 --> 01:16:38.900 But there is no need to model standard parts. 01:16:39.120 --> 01:16:44.320 There is also no need to have standard parts in your assembly in all 01:16:44.320 --> 01:16:44.840 details. 01:16:45.420 --> 01:16:50.880 Maybe if you have a bearing, it's enough to have a simple ring. 01:16:52.200 --> 01:16:56.240 And to say or make a note, this ring is my bearing. 01:16:56.660 --> 01:17:06.360 So we focus on our product, which is that hay wrapping thing, and not 01:17:06.360 --> 01:17:07.680 a single bearing. 01:17:09.620 --> 01:17:14.500 Of course, if we are product developer for ball bearings, it's our job 01:17:14.500 --> 01:17:19.820 to make ball bearing in all details, but not as a farmer's device 01:17:19.820 --> 01:17:20.880 producer. 01:17:22.220 --> 01:17:26.780 But make sure that all your standard parts are in place, and make sure 01:17:26.780 --> 01:17:29.080 that you have a list of all your standard parts. 01:17:29.340 --> 01:17:29.960 That's enough. 01:17:30.160 --> 01:17:33.560 You should know what you make, but there is no need to model it in all 01:17:33.560 --> 01:17:33.920 details. 01:17:35.920 --> 01:17:43.400 Okay, and make sure that all components of your complete mechanism are 01:17:43.400 --> 01:17:46.660 in the PDM system, and all for the packaging mechanism you can 01:17:46.660 --> 01:17:47.780 download from the library. 01:17:49.280 --> 01:17:56.200 Okay, I want to remind about the possibilities you have in terms of 01:17:56.200 --> 01:18:00.320 CAD lecture, which is today, CAD textbook and PDM textbook in German.
