Hidden geometry appears after export to Revit

[MikeWayzovski]

your best shot would be to export as .obj from SketchUp, and import that in Revit, saving one step:

Skp files to Revit - Without all the lines

You can try to smooth/soften all the edges in sketchup and the export as a .obj file with all your textures intact. Import into revit as an in place family in the correct category and most of the time it works fine with your extra internal edges hidden.
