This has probably been addressed, but could not find a solution in search. I’ve had this problem for 10+ years of SU use.
How do I prevent/get rid of these lines? They don’t seem to be triangles and they are on what seems like a single plane. If I export a 3d model of this, .dxf for example, and then import it back to SU, they show up as dotted lines that I can zoom in and tediously delete and then rebuild the surface from the outer edge. This model will eventually be exported to .stl for wax and bronze casting so I’d like to fix it. See attached PDF of screen shots.
