How to convert Revit complex building geometery into simple geometry in rhino

I am trying to convert a complex BIM model into Simple geometry in rhino for a research study. Is there any workaround for that. I have seen a lot of post for the rhino to Revit but couldn’t find anything for Revit to Rhino.
Thanks for the help in advance.

You can export a .dwg from Revit to open in Rhino

Even I am looking at a way to convert complex 3D surfaces into a single surface for use with Rhino.
For example: a facade with various frame thickness, glass components, floor thickness etc to just be a single surface
Tried .dwg export with ACIS solids but no luck.

See the above :slight_smile:
