Hi I have imported a 3d model into Mathematica converting it from a PLY or STL format. This works fine. By using the procedure in Slice through Graphics3D and modifying it slightly for a mesh region rather than a Graphics3D image I can get nice 2D elevations, plans and sections. The problem comes when I want to export those views in 2D via dxf into a cad program. It only seems to export the whole 3d model not just the 2d view. Any guidance as to how to get just the 2d view into a dxf format?
