• I have searched the existing issues

Problem description

Scenario:

1. Create one half of the arc and constrain it.
2. Add second arc using same point as center and join the "arms".

Expected results: Arcs are joined together, sketch is constrained.

Actual result: Cannot join the arcs.

Subproject(s) affected?

Sketcher

Anything else?

I believe this is a regression. Two arcs cannot be joined in FreeCad 21.0+. I verified this on 20.2 and it would be over-constrained but work.
