I am using rhino to make flat laser cut sheet metal parts. For that I need a .dxf or .dwg for the lasers CAM software. The problem I have is that Rhino is making extra lines in my solids.
I started with a closed curved -> Solid- Extrude Planar Curve - Straight.
Merged 0 polysurfaces. 1 polysurface could not be merged further.
Of course I can manually delete the curves in the .dxf but I want to remove the burden and chance for human error.
