Re: STL to STEP Lossless

Hi guys, I'm a 3D Artist who was given the task of converting an STL (3D Scanned) file to STEP file. In this case the stl came from a 3d scanner.

That said, this looks really strange, sadly it is probably very hard to reproduce and hence to find the cause and fix. It might already be solved in the 0.18.x releases.

Position several bodies relative to each other, manual placement, part container and nested parts 3. revisit 1. but use sp...
