Re: mesh to surface, how to do?

The one from my signature. Here is how: http://quaoar.su/files/cases/resurf.mp4 Cool! does that process use GeomPlate_BuildPlateSurface.hxx? 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...

Re: Parametric CAD modeler – CAD Builder

Just to avoid some misunderstanding in this regard (though, I am not a developer of CAD Builder). The very essence of this tool is to substitute the old Geom module in Salome. It's not going to compete with FreeCAD, and OCC devs are very grateful for this opportunity to grab a piece of FreeCAD's cod...

Re: Auto feature recognition algorithm implementation

We use AAG as a medium structure to iterate faces and query some precomputed props such as dihedral angles, neighbors, etc. Can you share a representative model (ideally in STEP) with a pocket?

Re: Auto feature recognition algorithm implementation

Well, I have to admit that my experiments with the volume decomposition approaches were quite limited (https://www.graphicon.ru/html/2016/papers/Pages_58-63.pdf -- RUSSIAN ONLY). Probably you have some fresh ideas on how you'd perform your decomposition. Are you going to use convex hulls of shapes, ...

Re: Auto feature recognition algorithm implementation

I have been searching for a while, however I guess there is no source code available for auto feature recognition for FreeCAD or native open cascade . I wonder if someone is working on it or are there plans to work on something like volumetric decomposition for feature detection. I have been workin...

It would be good to document the Mesh Design functionality in FC (unless it's already documented somewhere on the wiki). It would also be good to reference where in the OCC code we can find the unfolding-library files
That's a commercial package in fact. It is not available in sources.
