Re: Constraint sketch based on Part 3D information
i don't understand what you are talking about. le problem: I have two datum planes, both parallel to the Z axis. parallel ?? Planes aren't parallel to axes - they are orthogonal to them. Planes are defined by their normal vector and any point that lies on the plane. One plane, A, is coincident with ...

Re: Constraint sketch based on Part 3D information
You probably want to look at https://wiki.freecad.org/Basic_Attachment_Tutorial This is one important way sketches get placed relative to existing geometry.

Re: Help with the 'union' command in WorkBench Part
Better to widen the distance between the holes slightly so the two struts don't touch. I just made them slightly non-concentric as a proof of principle. Likewise, you can lift the struts off the surface slightly if you don't want them to fuse into a single object, or move them inward if you do. Free...

Re: Help with the 'union' command in WorkBench Part
FreeCAD doesn't like surface to surface contact. Moving the objects a few microns can fix it - exaggerated here. Presumably the desired object would have some clearance here.

Re: Problem with "App::PropertyIntegerConstraint"
Yes. If I save and restore, it no longer heeds the constraints.

Re: Help with the 'union' command in WorkBench Part
This can happen when you try to union objects which are only touching, not overlapped. Numerics can make this fail. Try adjusting to have a tiny (say 1 micron) overlap.

Seems to be a problem with 21.2 - up or downgrade should fix. viewtopic.php?p=735662#p735662 viewtopic.php?t=61707&start=130

Re: Two Face Sweep - One End Is Hollow
It doesn't like this with a dangling spine at one end.

Re: Swash Cylinder
I see - the cam opens a scissor like clamp. It occurs to me you might want the cam assymetric so it opens more slowly from the closed position where it is fighting the magnets. Here's a construction where you can specify the cam lift as a function of angle (actually circumference) in the sketch Mapp...
