Baking Revit geometry to Rhino with materials

The Text Panel above the Bake component shows the collection of Revit Elements. It doesn’t matter how you get them, the only caveat being that they actually contain geometry. A curtain wall is a ‘system’ & contains no geometry, but is a collection geometry.

Depends on how well structured your Revit Elements are.
