From Mesh
This command is used to convert meshes into CAD Surfaces. The CAD surfaces will keep the same type of geometry, i.e. a triangulated one.
Select the meshes you want to convert, and launch the command.
Note
This function does not convert a mesh into a CAD type model (IGES or STEP). It just makes compatible a mesh with another CAD model in order to be merged for subsequent steps (i.e. BIM inspection ).
