mesh to surface, how to do?
Hello again,
working with bones and implants the question appears: how to get a surface (FreeCAD understands) from a stl-file.
The file comes from meshmixer.
thanks a lot

This has very often been discussed: Part->ShapeFromMesh.

It doesn't produce any thing...it does create a feature in the tree, but nothing displays and error:

Re: mesh to surface, how to do?
I am using the german version the function is: part_WB -> Formteil -> Form aus Dreiecksnetz erstellen. For me this is "shape from mesh".
But no effect, even a new part in the tree without any geometrie.
It works if a solid, from meshmixer for example, is used, not in case of a shape.

Re: mesh to surface, how to do?
It seems your intent is to convert faceted mesh into curved surface (NURBS). Right?
But this is not design intent of "Mesh to surface".
"Mesh to surface" is design to handle very simple mesh model.
What you need is "Reverse Engineering"(RE) tool.
FreeCAD has 2 RE workbench, but both limited abilities.
1. stock installed, Reverse Engineer workbench.
2. from Addon Manager, Mesh Remodel. (or something like that).

Works flawless here (tolerance 0.1), file is too big to attach, even without the FEM result: OS: macOS High Sierra (10.13)

Re: mesh to surface, how to do?
Nope:
No display, but the file is 13Mb after executing Create shape from mesh...
Update: and if I load the file where it has worked from this thread: https://forum.freecadweb.org/viewtopic.php?f=3&t=48186
It gets the same error when the file is loaded and nothing displayed...
Update: If I load the original file and set the tolerance to 0.01, instead of 0.1 it works. So why does it work at 0.1 on yours?
