This may be a good issue for someone wanting to eventually get deep into the geometry code of Solvespace.

issue:

Triangulating a NURBS surface is currently O(n^2) operation, and in many cases it doesn't produce very good triangles. We should be able to have better quality in O(n*log(n)) time.

background

For surfaces with compound curvature (a torus for example) we use "grid triangul

Needs to be updated to use the or string selector, fluent api, and remove the saveModel call.

Tuo Xie requested the ability to visualize clocking (pins & wires I believe). We should make it easier to visualize subsets of the device routing resource and types of routing nets.

Proposed Behaviour

Add filtering to the rr_nodes displayed (ToggleRR), and to the nets displayed (ToggleNets). I think we should have an option to filter what is shown by node type, node name (segment or pin t

dwgadd is unusable:

• Need of "\n" at begin of first string, sic.
• issue with initial = 1 at begin and setting to intial after initialization
• No error message to stderr in each exit(1)
• Missing error in stderr in dwg_add_dat (&dwgp, &dat) != 0

Sometimes bugs can get introduced that cause Fornjot to panic, if one of the models from the repository is run.I try to test all the models regularly, but sometimes a bug slips through.

It would be great, if as part of the regular CI build, all models would get run. Opening a window to show the model won't work on the CI server, so maybe exporting the model (`cargo run -- --model --expo
