If your job requires working on Revit models created by someone else, then you have probably run into situations where portions of the model need to be reworked. Perhaps you're a subcontractor or an interior designer who needs to accurately convey finishes. Traditionally tasks like these would require a good deal of time, but with the three unique construction modeling tools in Revit, you can now add the details and refinements you need without rebuilding the entire model. Paul F. Aubin shows how model elements can be broken down into parts and articulated with their own finishes, materials, and other details. To assist in documentation, Paul explores assemblies: detailed drawings of isolated portions of the model. And with the Displace feature he shows how to create compelling "exploded view" illustrations to convey how things fit together.
So there's many ways we can use parts to communicate our intent. As we've been seeing in several of the other movies, we can use parts as a way of taking an overall model and being more specific about how the parts and pieces will actually fit together in a construction scenario. We can also use Parts as a way of communicating other things about our model. Like, for example, maybe I want to take this wall assembly that we see onscreen here and I want to do a diagram that actually shows how all the layers fit together. I can use the Parts feature to help me do that and specifically the shape handles of the Parts feature.
So in this movie, I'd like to look at that, and I'm in a file called Shape Handles. And it's, again, just this simple wall assembly that we see here on screen. So, of course, the first thing I need to do is select that, and it's just the out of the box exterior brick on CMU wall and create parts from it. When I do, you'll see that I get a part from each layer. And if I select one of these parts, like the brick layer. If you look over on the Properties palette, you'll see lots of useful information.
Now, all of this at the top is grayed out. It's all just read only information, but it's still pretty valuable to know the area and the size of that information. But as I scroll down a little bit further, I'll notice under Identity Data that there's this check box available here called Show Shape Handles. Now if I check that, and then apply that by moving my mouse back into the screen, you'll see a series of shape handles up here surrounding the part. And what's neat about these is I can now use these to actually manipulate the shape of that part.
Now I could make it larger. I'm not really sure that there would be to many instances where I would really want to do that. Or I could actually make it smaller. Now in this case because I'm after a diagram, more of an explanation, of how the wall goes together. Making it smaller is appropriate. And I'm actually going to reduce it's size in both the vertical and horizontal directions. Now I can repeat the process by selecting the next layer back, turning on its shape handles, and adjusting it, and then continuing.
And of course I'll leave the last layer at its original size. Now I have a very nice diagram that shows me how each of the layers kind of stacks up to create this total wall assembly. And I might actually want to go a little bit further now and add some annotation on here. Now because I'm in the 3D view, I can't actually annotate directly unless I first lock the orientation of the view. So I can do that down here on the view control bar, using this pop up right here, that allows me to save the orientation of the view, and lock it.
So I'm going to choose that, And now I could add dimensions, text, tags, any kind of annotation directly to this view. So I'm going to use some material tags here. I'll just simply click the material tag, highlight the bricklayer, pull out where I want the leader to go and then just repeat that. With each of the layers and then when you're all done you can Cancel out of the Command. Do any other fine tuning that you like but now I've created a very nice diagram that shows me how my wall assembly goes together and I've called out each of those materials.
Now I use material tags here, you could just as easily use keynotes or other kinds of annotation, and it would work the same way. Just make sure that you lock the orientation of the view before you add your annotation. So using our parts we can do more than just modeling the entire building, We can actually use parts as a way of creating very specialized kinds of details and diagrams which can be really helpful in our overall documentation set.
