Wow, really nice Pi project!! Have you published the full project anywhere?? Rob On 15/02/17 23:26, nop head wrote: > Another DRY technique I use is my connector modules take a cutout > flag.

It is a preview artifact, but... When doing CSG and having two faces exactly coplanar can cause CGAL issues. On their own they are not a problem, but say you added another object that covered part of the hole coplanar with the top, then it doesn't know if that face is there or not. Often getting a non-manifold error. Similar issues unioning two objects with coplanar faces, sometimes OK, but bite you in the arse when you're not expecting it. Experience says extend your cuts and embed you joins. ----- Admin - PM me if you need anything, or if I've done something stupid...
