This is something that I get asked quite a bit…when I load in a Revit file into Navisworks, why do things like Columns or Doors (as examples) always show the Type Name twice?
If you’re not sure what I’m talking about, here’s a little screen shot…
As you can see, the W10x49 has a “sub component” also called W10x49. What you are really seeing here is the Element and the Type (respectively). To help explain this a little further, here’s each one selected and the associated “Element” properties…
As you can see in the image on the left, the Properties for the first item selected displays the Instance Properties of the Revit object. On the right image, you can see the next item in the list is selected, which is now displaying the Type Properties.
So when you see Revit objects with what seem to be duplicate names, you are actually seeing the Instance and the Type. One thing to note, this isn’t the same for all Revit objects. Take Walls for instance, Navisworks only lists out the Instance and the actual geometry (as shown in the top image).
From what I can tell, this helps separate out the Properties and the number of tabs that are displayed. But, there is an issue with having all of these properties broken out like this, specifically the Element ID! This ties back to the Switchback post…if you try and use Switchback with the Type selected, it won’t find the object. And, that’s not all…it also affects your Clash Detection reports! More to come on that subject soon….
