Recently I have had quite a few support calls regarding the linking or inserting of 3D AutoCAD drawings into Revit projects.
3D Drawing files from products such as AutoCAD Architecture, AutoCAD MEP or even Fabrication CADmep can be very useful when coordinating or comparing layouts in Revit.
However by linking or inserting a 3D .dwg file directly into your Revit project, you may experience problems with views not displaying as expected.
Below is a very obvious example of a 3D .dwg file linked directly into a new Revit project. This incorrectly shows the floor plan displaying from above and the section showing what looks like an elevation:
The way to fix this, is to import the 3D .dwg file into a new family (for this example I used the Metric Generic Model template) , and then load that family into your Revit project.
Now your Revit sections cut through the drawing as expected, and your floor plan views correctly:
