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.

Topics include:
  • Creating and removing parts
  • Dividing parts
  • Adding and merging parts
  • Creating parts from linked files
  • Creating assemblies, assembly views, and assembly sheets
  • Creating and editing displacements sets
  • Controlling displacement views

Dividing parts

Once you create some parts, you'll probably want to start dividing them up. One of the reasons we have parts in the first place is to be able to take some larger component that was created by a designer and start breaking up into smaller pieces that represent how it might actually fit together. So I'm in a file here called Elements and I'm going to take this wall over here and I'm simply going to turn that into parts. So if you recall from the previous movie, we simply select the object. Here on the ribbon we'll get the create parts button. We'll click that. And now I have parts here.

I'm just going to roll my wheel to zoom in. You can see I have parts here indicating each of the layers. Now let's say that I want to start breaking this up into smaller segments. I have this really tall. Layer here and the same thing on the other side. And maybe I want to start breaking that up a little bit. So I'm going to select the bricklayer here, and using the Shift key and the wheel, I'm going to orbit my view around, so I can see the other side. And I want to sub-divide this into two sections. So all you have to do is select your part.

And then up here on the ribbon will be several context tools. And I'm going to choose the divide parts command. This will allow me to divide the parts into couple different ways. I'm going to do this by editing the sketch. I can do that by using the edit sketch button here on the ribbon. And this will give me my standard complement of sketch tools, but I want to point out to you here at the bottom of the wall layer is this small dashed outline indicating where the current work plane is for my sketch, and as you can see that's oriented with the plan view, or the top orientation.

So I actually want to change the sketch on the vertical surface of this wall. So the first thing I want to do is click the Set button right here which is going to set the work plane, to some other orientation, and I'm going to choose the Pick a plane option, click OK. And then that will allow me to click any existing plane in my model. So I'm going to click this front surface of the brick layer. That now becomes my work plane and you can see that indicated with the dash line now. Now I can simply add a sketch line.

And that sketch line will become the division between the two parts. Now I'm going to press Escape once to just cancel the current drawing action. And I want to point out that I've drawn my sketch line past the extense of the brick layer. In this context that's actually okay. And I know that might be a little confusing if you've been using Revit for awhile because normally that would not be allowed in the sketch mode. Normally you'd have to make a nice tight close sketch. But in Parts The rules are a little bit different. It's actually desirable in some cases, to do more exaggerated lines like I've done here.

So, when I finish this, it's actually going to segment that one part layer into four separate sections. And then I'm going to finish again, and now as you can see I have one two, three, four parts that are created from that single brick layer. So this is how you can take your parts and start carving them up into smaller segments that can begin to indicate how you want to actually fit this thing together.
