In fact there is a lack of compatibility
among SAP (I use VER 11) and AUTOCAD ( I use ver 2008) in what matters to 3d solid.
The entity the sap creates when exposting a solid element is recognized in dxf format in autocad as "polygon mesh".
This is an entity that is not possible (tought) to create in autocad....so....
I have a problem.
I need to build a cube, in granite, with a cylindrical hole to engange some kind of dowell....
Thanks for any help...
