Hi ! This is Charley.
Say, “back in the day” when I was first experiencing make2d (can’t remember now if it was at -3 or at -4) I encountered a problem with make2D and the fact that it was pretty far from the origin turned out to be the problem back then, too.
Once we discovered that was the culprit, I 1. Moved it closer to world 0,0,0 , 2. ran make2D getting hoped-for results which I was able to use successfully, and 3. suggested developers plug in a temporary calc-from origin at the geometric center of the items being extracted to 2D.
ANY progress in the nearly last almost 10 years on #3 ? There’s really no excuse that this, this far along, is still something we’re dealing with. Also, we STILL find lines on top of lines, altho this is noticeably reduced, and small curves aren’t represented accurately, with intersections sometimes overlapping, tangent surface-edges not appearing right or not appearing at all (so I’ve turned these OFF in the settings) and some curves that SHOULD be hidden, falling behind an obscuring surface, STILL showing up and having to be CLEANED UP (tedious).
Now don’t get me wrong, faster and NOTICEABLY BETTER results, yeah, I move my -5 models to -6 to run, but these are the things I’ve noticed. Ok, ALL the VERY BEST to you and the TEAM !
