there's no easy way to implement that with NURBS
<whitequark>
and there's only one hard way, use OpenCASCADE, which is awful in too many ways to go there

the robustness of the 3d engine of solvespace is quite amazing. alas, it has its limitations, too. i currently have a project where i need a thread. openscad can do that for me, just have to merge this with the more complex bits from solvespace. but that openscad 3d engine(s) experience ... pure horror. just as bad as something like a decade ago :(

yeah

i wish i had more time to dedicate to solvespace, but, health doesn't permit
