It seems that maybe both issues are possibly caused by the ancient version of SolidWorks. Additionally, the simple test file I made with just a non-extruded square in it, though it didn’t have the funny lines, did have a duplicate of the shape. I use SolidWorks because I’m making 3D models, and most of the pieces I need to cut are far more complex than the example here each piece contains numerous sketches, and so can’t be exported as a single non-extruded sketch. Jim - If the pieces I was preparing to cut were just flat planes, I would likely use a drawing program or Lightburn to draw them. Marcus - I was very hopeful that this would be a solution, but nope… The view was set to Shaded, not Wireframe I changed it to Hidden Lines Removed, but the resulting DXF file still had the duplicates and the extra lines.


Berainlb - There are no redundant components in the SolidWorks file.
