Is it possible that you used undo? I had been looking for an error and finally could reproduce it, see https://forum.freecadweb.org/viewtopic.php?f=3&t=46419. Werner has already fixed it. Please retest as soon as you get the updated version.

Re: Sketcher Constraints checkbox -- What does it do?
Just saw that. I probably used undo somewhere in there. I've been trying to pay a little closer attention to what I'm doing to see if I can reproduce it. One other thing I've run into but haven't been able to reproduce is a disconnect of constraints tieing the origin of an arc to the origin of the sketch -- I delete some lines and constraints, add in new ones, and then notice arcs which haven't been touched can be moved, even though their radius is set and their endpoints are again tied to other fully-constrained parts of the sketch. On closer inspection I can see their center is floating.chrisb wrote: ↑Sat May 23, 2020 9:18 pm Is it possible that you used undo?

I'll see if I can build a new version and keep an eye out for any oddities.
Re: Sketcher Constraints checkbox -- What does it do?
If the solver reports an error, e.g. redundant constraints, then subsequently added constraints are not shown correctly until you remove the error. So if you have such an error and after that you add a circle, starting with autoconstraints and you make the centers coincident, they well can show different positions.

Re: Sketcher Constraints checkbox -- What does it do?
In this case there may have been earlier errors; if so, they were all corrected. I can't remember if there were actual errors or just insufficient constraints as a result of removing some lines and then adding new ones. No arcs were added in, just straight lines. The sketch would have been fully constrained if the centers of the arcs hadn't been disconnected from the origin. Once they were manually re-made coincident with the origin, the sketch was fully constrained.chrisb wrote: ↑Sun May 24, 2020 6:43 am If the solver reports an error, e.g. redundant constraints, then subsequently added constraints are not shown correctly until you remove the error.

Still trying to build with the new version; having some python version issues.
