Wondering if there is anybody willing to help with the development of the ImportNURBS 3DM workbench...
Do you already have a mapping between OpenCascade's TopoDS and Rhino's OpenNURBS? I was going to start working on such a bidirectional converter, but it seems it's quite some effort.

I don't want to sound too negative, I do appreciate what you have done but... it's no wonder you get little involvement from the community, you make it too difficult. You have that stupid contributors agreement thingy which immediately turns off a lot of people. Then You enforce, or at least used t...

Re: OpenCascade Fillet Fiasco

OpenCascade has a long list of paying customers: https://www.opencascade.com/content/trusted-industries Is there really no one who asks for improved fillets?

Re: OpenCascade Fillet Fiasco

Shame on you OpenCascade. If you provide a simple scenario, we can prepare a bug report using the conventional bug reproducing practice (one shape, faces to blend, Tcl script). On behalf of OCC devs, I can assure you that everybody here is interested in making FreeCAD better, but you have to embrac...

Re: How many man hours would FreeCAD need to reach feature parity with SolidWorks/SolidEdge?

... the best place to start would be at the kernel, which currently lacks thread protection, making multi-threading difficult or impossible. Do not trust people speculating on parallelism and/or GPU magic. That's bullshit. Parasolid outcompetes any other kernel in a single-threaded mode. Lack of pa...

Nope, that's a least-squares surface fitting with aggregated smoothing functional. The sources are attached (it's a tiny NURBS evaluation lib based on The NUR...
