Exploded Views For Assembly Drawings
05.31
| 00:00 | - As we've already covered in this section of the course, the key details for each part should be on its own individual part drawing. |
| 00:07 | The assembly drawing on the other hand, should be specifically about the assembly of the components, how they fit together and the resulting dimensions. |
| 00:15 | Most of the information we've discussed already around part drawings is still relevant for assembly drawings and can be used to show the assembly specific information. |
| 00:26 | With that said, there are some drawing features that are only suitable for the use on assembly drawings. |
| 00:31 | Exploded views would be one of these. |
| 00:34 | Exploded views show the components of an assembly separated and suspended in space as if there was a small explosion in the middle of the assembly and the parts were frozen just after separating. |
| 00:46 | These views are usually shown from an isometric projection angle and help to define the relationship or order of assembly of the components. |
| 00:54 | To see how this works, let's jump back into our wheel hub model. |
| 00:58 | This time though we'll use the assembly with the inner and outer wheel bearings, inner grease seal and the wheel studs included. |
| 01:07 | Ignoring the missing brake rotor, these are all the press fit parts assembled to the hub before it's ready to be attached over the spindle with the additional hardware and a dust cap. |
| 01:18 | Before we get started on our drawing, we actually need to set up the exploded view in our assembly design file. |
| 01:25 | This is done under the animation workspace so let's navigate there from our drop down menu. |
| 01:31 | For this job we'll be using the tools under our transform tab to explode the assembly. |
| 01:36 | Let's try the automatic tool first to save some time. |
| 01:40 | We want to make sure we're viewing the model from the same angle we intend to use for the drawing so we get a good representation of our finished exploded view. |
| 01:50 | Let's click the home view icon and we'll use the default view. |
| 01:54 | First we click and drag to select all components and then select the automatic explode, all levels icon, or hit U on our keyboard. |
| 02:03 | In this case, it's worked well and we can see that our assembly has exploded in the desired direction. |
| 02:10 | Sometimes depending on the model geometry, it doesn't quite go how we'd like so we can change the position of the components manually. |
| 02:18 | We can drag the explosion scale bar out of it to separate the components further and also add in trail lines to help show where each component fits when assembled together. |
| 02:28 | To finish this step, we click the green tick. |
| 02:31 | Let's just use the transform tool to make some small adjustments to components and lay everything out nicely, creating a bit more space between the inner bearing and the seal. |
| 02:41 | The animation workspace can also be used to make short videos to showcase our design. |
| 02:46 | If you've ever edited a video before, the timeline works similar to editing software like Premier Pro or Final Cut. |
| 02:53 | We don't really need to go any further into this topic but it's a good feature to play around with and you may find it useful at some stage. |
| 03:01 | Down below the timeline we can see the storyboard one label, here we can create other views if we need to. |
| 03:07 | Let's right click and rename the label to exploded view one. |
| 03:11 | Making sure our design has been saved, we can now open a new drawing from the design using our assembly drawing template. |
| 03:18 | This drawing has two sheets with some standard projected views on the first page, intended to be used for dimensions and notes as we've covered already. |
| 03:27 | On the second page we have an isometric view which we'll change out for an exploded representation. |
| 03:32 | Unfortunately we can't just change the view that's there already so we need to delete this then select our base view tool and then in the pop up window, change the representation from model to exploded view one. |
| 03:47 | With orientation at the default home view, we'll leave all the other preferences as they are just changing the visibility of tangent, interference and threaded edges to full length. |
| 03:57 | Then we can place the view in the middle of the page. |
| 04:00 | Now we have our exploded view in place with the trail lines giving a clear illustration of how the components assemble together. |
| 04:07 | Let's add some labels and a part list, also known as a bomb table for the components. |
| 04:12 | Under the table tab we can select the part list icon and then select an anchor point for this table at the bottom left hand corner of the page. |
| 04:21 | Double clicking the table again, we can change the direction preference to down so it reads more naturally from top to bottom. |
| 04:28 | Let's also change the columns to include only the item number, quantity and the part name for this example and change the order to item name then quantity for clarity. |
| 04:38 | Other columns can also be used depending on what information we want to show. |
| 04:43 | Our final result is a clear view of each component and how they form an assembly. |
| 04:48 | And that's all there really is to it. |
| 04:50 | So in summary, exploded views are necessary for showing how components fit together and can be used for showing the order of assembly. |
| 04:57 | Before adding these views to our drawings, they need to be set up in the animation workspace of our design using the explode and transform tools. |
| 05:06 | We may also want to include trail lines if it helps with understanding the illustration but for complex models it could also take away from the clarity. |
| 05:15 | After we've saved the exploded view, we can add the view to our assembly drawing by changing the representation setting in the view pop up box, then add the parts list and corresponding balloon notes to easily identify the components. |
