The master sketches work, but are rough. That's where I expose a bug in FreeCAD. When I animate the master sketches through the XY plane, the sketch will "flip over" or map reverse. That's the primary bug I've been talking about.
I was thinking that you had run into the FreeCAD topological naming issue, which is indeed one of FreeCAD's main weaknesses, but in your case that's not ... the case. You attach Sketch_cv_shat_path
with a "Plane by 3 points" , therefore when the 3rd point passes over the 2 others, then it is logical that it flips over. That's not a FreeCAD bug, that's the result of your construction.
I have always found that construction with "Align O X Y" types are much better because you can better choose the directions. In your case, I'd try to attach the Sketch (or LCS) to a vertex, then X to the line in Sketch_inner_joint_track
, and choose/construct the 3rd point such that it is always on the same side. You can even construct a virtual, non-real-world, point for that. Plane by 3 points
is easier but less deterministic.
