Make2D of archicad model imported into rhino mac

I’m a student studying architecture and I am involved in a class project where we compiled our information to make a group model, and they chose to do it in archiCAD.

I usually work with rhino and so I’ve imported the model into rhino (mac) as a dwg file but I am unable to apply simple commands to it such as split or make2D. I have tried meshtonurb but still unable to do anything with it.

Can anyone tell me why this is happening and how I can fix it?


What was the result of the MeshToNURB command and what were you unable to do with that result?

Do you have example data or a screenshot of the model?

It could be that you´ve just imported “box outlines”, not “real” 3D data.
