Cutting 3D CAD Files

When you are using 3D CAD files in your Revit models, whether it is for a topography, an existing building or a piece of furniture, one thing you might notice is that if you place a section marker that cuts the 3D CAD files it won’t show as being cut and even worse it will show the full extent of the CAD model, even if parts of it are behind the section mark.

                

To get the 3D CAD file showing properly in section, you have to import the 3D CAD file in an In-Place family.

Create a new In-Place Component Family selecting the Category most appropriate, and then Import the 3D CAD file. Finish the In-Place Family.

Now the section will show properly. Just remember the cut line work will now take on the style of the category.

This procedure also work by inserting the CAD file into an external component family.
