When change often really fast scale, direction, generally views or anything else with many views like in the projection group task, then FreeCAD can (must not) crash. Normally that is not a problem, if that happens, then someone demand this.
I see where this fails, but I can't make it happen. Can you reproduce this on command, or is it random?

More or less random. For example when i change very fast the direction. Sometimes i need 10 clicks, sometimes in need much more. But as said, very fast. In the video i clicks around 7-8 times per second.

This post is, maybe, offtopic. I want to share 2 pages of my assembly instructions generated totally with mutithreading branch of TD. All pictures and details were generated in FC, with some touches in Inkscape.

I didn't have any hickups and everything was painless and very fast compared to working with version in master. According to some rough measurement generation of pictures is 7-8 times faster.

Thank you for your work.

This is sounding like quality work, I'm hoping to get some time this weekend to give it a spin with some new and older files. Thanks to all involved.

The closest to a crash I can get is to invalidate Dimension references by pressing buttons in TaskProjectGroup as fast as I can. Maybe my finger are just not fast enough.

In any case, I have added some protections to prevent the crash in extractFaces. Let me know if you manage to crash the new version.

Many thanks! This feature is a must have in the master.

There are plans to multithread other parts of FreeCAD, constraints in sketcher for example.?
