I am loving Shapr3D so far, but this one issue is driving me crazy. I have a rather complex and large object that I need to subtract from. I have tried pushing the face down with a sketch, but it says “body generation failed after extrusion”. When I try to create a shape and then use the subtract tool, I get an error saying “the boolean failed”.
Thank you very much Daniel. That was in fact the issue.
I presume it was considered a non manifold because those two lines intersected together at the edge. That’s surprising to me because those lines are semi-randomly overlayed on top of the surface. It was just a coincidence that the intersection happened to be so close to the edge that they were considered touching.
