Hi Matti, and sorry for the late reply.

I made some tests and trials but could not find a solution.

Could you please try to export your model in a solid format such as Parasolid or STEP? Also make sure that all the exported parts in the model are solids and not surfaces.

Hi,

thank you for your reply!

I cant find any option in either Revit or AutoCAD to export those formats.

Is there any other solution?

Thanks
