Re: Crash on using Mephisto and Netgen mesher

Do you run the binaries on your own? At almost the end of Mesher::createMesh() (src/Mod/MeshPart/App/Mesher.cpp) the smesh is deleted and for macOS this causes problems. You can disable this line (delete mesh;) and retry the meshing several times. However, you likely get a memory leak then.

Re: x32 Win build failure

Apparently you have found a solution. So, just for the record the tracker issue opened by vejmarie was issue #2612 and the corresponding PR was: https://github.com/FreeCAD/FreeCAD/pull/208/files

Re: Convert STEP to Wavefront OBJ with colors of faces

import Mesh
ModuleNotFoundError: No module named 'Mesh'
Depending on your OS your FreeCAD installation should have a file Mesh.pyd (Windows) or Mesh.so (Linux or macOS). Can you find the file?

Re: Crash on using Mephisto and Netgen mesher

Can you run FreeCAD within the context of a debugger (on OSX the tool is lldb IIRC)?

So, it should be something like

Code: Select all

lldb ./FreeCAD
run
# crash

Re: Part API Euler Spirals?

What are you thinking about that? Like we can create lines circles or arcs by using api and it return a shape and we can use that shape. I want something similar for spiral While lines, circles or arcs are directly supported by OCCT this is not the case for Euler spirals. So, the only feasible way ...

Re: Mesh decimate algorithm

So the FreeCAD Mesh code that performs decimation is the same as sp4cerat?
FreeCAD uses the modified sp4cerat code: https://github.com/sp4cerat/Fast-Quadri ... Simplify.h

Re: [Solved] Skip excution for some properties

Re: AppImage Startet nicht Rechnern mit AMDGPU Driver unter Linux/KDE

Da hilft wahrscheinlich nur freecad von den system bibliotheken zu verwenden bis libstc++ in conda aktualisiert ist (Aber ich glaub das geht nicht so schnell) Mit ./FreeCAD_xyz.AppImage --appimage-extract kann man ein AppImage entpacken und man kann manuell die libstdc++ ersetzen. Lässt sich dann h...
