If you import an FBX model from Revit in 3ds Max you will most likely see more polygonal edges than expected. Those are not extra polygons, it is simply that generally, 3ds Max hides adjacent edges by default. In the case of FBX import, meshes are created with all edges being visible – and the viewport does not look as clean as it should:

To get rid of those edges, you can hide them from the editable mesh panel:

Or better, use a Maxscript tool that will let you hide them all at once.

Usage: Select all your EditableMesh objects and execute the script. The script will only affect selected EditableMesh objects so the selection can contain lights, lines, cameras: they won’t be affected by the script.

The result:

Special Thanks to Chris P. Johnson who helped improving the speed and stability of the script on large models containing several instances.
