Additionally, I have found some existing issues: * #5931 (possibly solvable by [#5960](https://github.com/openscad/openscad/pull/5960)) * #5732 (already fixed -- though it suggests a different format for output, which may or may...

I just went back to update a design I built without attachments. It was so much worse. Attachments are my favorite thing about BOSL2; it makes writing things so much...

So this seems to work; can you confirm and close the issue?

Still present.

Some backtrace: ``` #0 roof_vd::vd_inner_faces (vd=..., segments=std::vector of length 14, capacity 16 = {...}, fa=fa@entry=12, fs=fs@entry=268435456) at /opt/prg/openscad/src/geometry/roof_vd.cc:266 #1 0x0000555555caf0b0 in roof_vd::voronoi_diagram_roof (poly=, fa=12, fs=2) at /opt/prg/openscad/src/geometry/roof_vd.cc:360 #2 0x0000555555b4d5cc in...

I think the code lines are one of these: ``` Vector2d v0(edge->vertex0()->x(), edge->vertex0()->y()), v1(edge->vertex1()->x(), edge->vertex1()->y()); ``` which makes it likely #6291 points out the cause?

So if you want to know what's going on: Read the first paragraph: https://www.boost.org/doc/libs/latest/libs/polygon/doc/voronoi_diagram.htm Edges are the black lines, some of which stretch off into infinity. then look at this...

I use the Manifold backend and the problem does not repro at step 3. Recent build from HEAD.
