Re: mesh to surface, how to do?
I tried on Ubuntu and can confirm your behaviour. But here comes the strange thing: I saved the file and opened it on the Mac: And I can see the Shape!
So It's a display issue, not a mesh issue.

Re: mesh to surface, how to do?
Yeah, and i confirmed it on same Ubuntu, different PC's, one radeon, one nvidia.

Re: mesh to surface, how to do?
I think I see what might be causing the issue...but, I guess I don't understand what the graphics driver would have to do with it.
If I use 0.01 to get it to mesh I can see voids in the resulting shape.
If I then look at those areas on the original mesh (circled in red here:
And zoomed up here:
Similar voids on the left socket as well...

Cool! does that process use GeomPlate_BuildPlateSurface.hxx?Quaoar wrote: ↑Mon Jun 29, 2020 9:29 pm The one from my signature. Here is how: http://quaoar.su/files/cases/resurf.mp4
Re: mesh to surface, how to do?
Could be a very nice feature for freecad.
Re: mesh to surface, how to do?
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 NURBS Book, a part of my indie research). For integration with FreeCAD, I guess, it might make sense to rewrite on BSplCLib/BSplSLib, though conversion between Piegl's B-surface and OCCT B-surface is quite trivial.tanderson69 wrote: ↑Tue Jun 30, 2020 6:00 pmCool! does that process use GeomPlate_BuildPlateSurface.hxx?Quaoar wrote: ↑Mon Jun 29, 2020 9:29 pm The one from my signature.

The code of interest is geom_ApproxBSurf.h/.cpp
