And I know of homes in the 1983 Ash Wednesday fires that were prepared with water pumps and sprays, but they were run by electricity, and the fires cut off the power in the area... To be honest, that even sounds silly. When watching the video that Jim linked, I was kinda wondering, what are they us...

I am not quite sure if you are talking about that, but there was work to allow toggling external geometry "out of construction mode" to become part of the contour. It was mostly finished, but I don't know the current state of things. Abdullah, who worked on it, seems to be away from FreeCAD now for ...

Woow, that's tr00!

How did you make the rays?

In a past life, and another modeling engine you could fix it by increasing the number of chords used to approximate the circles. That modeling engine had a tolerance for overlap. But, that was a long time ago...in galaxy far, far away. :lol: FreeCAD/OCC also has tolerances, although it's not relate...

I get that this is probably tolerance between the overlap cause the model engine to get it's knickers in a twist. Yes. Just give it some overlap for well-defined intersection. Coincident faces are usually not a problem for OCC, but in case of threads, the inner face of the thread sweep is a bspline...

Can you tell me what I'm doing wrong?

Seems good to me, nothing obvious to cause a memory leak.

What is your FreeCAD version, btw? (see IMPORTANT: Please read first before asking for help for how to post it)

After changing it the behaviour is a bit funny now because when pressing the H key then it performs both operations. For the press event the horizontal constraint is set and for its release event the rotation center is set.

For me, it has always been this way.

That's why I prefer to change the implementation of the Gesture style not to handle the key press but the key release events. Shouldn't be a problem. Do you want me to create a PR? A better solution is to avoid the conflict altogether. It is also in conflict with shortcut for H-constraint in Sketch...

Looks like you need to use C++14

... But generally speaking maybe supporting C++11 still makes some sense?

I didn't know I am using c++14 features. I aimed for c++11. I guess my toolchain supports c++14, which made me use some c++14 features by accident.

In addition would it be possible to provide an example code snippet to test:

see src/Mod/ConstraintSolver/examples for a starting point. Though they might not work right now...
