IMPORT CAD DUCT

IF you import a .dwg exported from CAD-Duct or CAD MEP you will get and error message:

When you go into AutoCAD MEP and change PROXYGRAPHICS to 1, then reimport the drawing, it has been flattened into a 2D block.

Because Revit does not have an Object Enabler, we have found this workaround for importing 3D geometry from AutoCAD MEP into Revit MEP:

• 1. In AutoCAD MEP go to a 3D view

  2. Zoom Extents.

  3. Type Convertto3DSolids at the command line.

  4. Export to AutoCAD.

  5. Create a new Generic Model Revit family (or other category like Mechanical Equipment).

  6. Import the .dwg.

  7. Load the family into your Revit project.

The family should now be a 3D block in Revit that is a cuttable object in plans and sections.

One thing to keep in mind is that while the Projection Lines can be globally controlled by the Object Style, or overridden in the Visibility Graphics for Imported Categories in the View, the Cut Pattern is governed by the Generic Model category.
