Re: [Techdraw] Segmentation fault

Hi, Updated FreeCAD today to the Git 34789 version, and there is no crash when updating the cylinder position. I still get error messages: DVP::getProjVertexByIndex(11) - invalid index DVP::getProjVertexByIndex(13) - invalid index CL::scaledGeometry - failed to calculate endpoints! CE::addCenterLine...

[Techdraw] Segmentation fault

Hi all, Possibly found a bug in the TechDraw workbench : 1) open the joined model (BagueMoteur2023.FCStd), 2) select the "Cylinder" Part object, 3) change it's Z position to 15.000 mm, => FreeCAD crash with segfault. should I open an new issue in the tracker ? DVP::getProjVertexByIndex(11)...

It's a good workaround, but not the regression bug correction...

Re: [Sketcher] Wrong external geometry of elliptical arc

The patch also work fine with another sketch orientation (45° around Y):

Re: [Sketcher] Wrong external geometry of elliptical arc

Hi Syres Thanks for the prompt reply and patch. The patch work fine when both sketches are in the same plane (this was the exposed case in my first message) but the problem persist when the sketches aren't in the same plane.

[Sketcher] Wrong external geometry of elliptical arc

Hi all, I recently came across a problem in the Sketcher To reproduce: - Create a sketch, - create an arc of ellipse in the sketch, - close the first sketch, - create another sketch in the same plane, - create an external copy of the arc of ellipse from the first sketch => The copy created is the fu...

Yes, at the beginning of my investigations, I got the same messages and the solver did not indicate the overconstraints

Re: Solver fails, FreeCAD hangs and closes abruptly

Hi Mark81 Due to the mathematical of Bézier curves (https://en.wikipedia.org/wiki/B%C3%A9zier_curve), you cant have an absolute position on both curve points and control points. What you try to do when you fix both curve points symmetry and control points symmetry generate overconstraints. I made a ...
