Dear OpenSCAD users,
I want to export my model into STL for 3D printing, but do not get past the preview phase.
This model is simple enough to share with you (attached), but you will need the experimental (?) roof()-Feature of the nightly builds.
It is a simple plastic piece for wooden toy train tracks in the shape of a gym dumbbell. I could probably work around roof() to achieve the same model, but I would like to understand if I did something wrong.
I fail on
OpenSCAD-2024.01.03.ai18006-x86_64.AppImage
ERROR: Rendering cancelled by exception Unauthorized intersections of constraints
OpenSCAD-2023.03.05.ai13734-x86_64.AppImage
ERROR: CGAL error in CGALUtils::applyUnion3DHybrid: CGAL ERROR: assertion violation!
I attached:
- OpenSCAD source code
- error messages in the source code
- a preview the model
Cheers,
Marcus

Maybe try to enable manifold instead of fast-csg? We have some bug fixes
there.
Note that you should flush the cache before trying to do F6 render, the
cache from F5 preview may interfere with manifold (known bug) and cause
failure.

The cached preview can also break CGAL, so it is always worth trying a
flush between F5 and F6.

What does "failure" mean? Error message or silent creation of an
incorrectly formed model?

I suspect that, for some reason, roof() generates a non-manifold object and Manifold complains.
Definitely worth looking into; we don’t have that many tests for this particular combination yet.
@pca006132 I can reproduce this on macOS built from master - can you?

I guess roof is creating some invalid geometry because it was written
without using indexed polyset, but this is just a guess, I cannot verify it
for now. Sorry cannot help much here, not with my computer now.

Error message.

I use a bit of code from thingyverse for filleting this sort of shape.
You could modify it for chamfers, I expect. Or, you could make the shape
a bit smaller, and use Minkowski with a sphere. I've attached the
filleting code below. (fillets3d.scad)
