Constraints bug (by Andrew Bromley)
Using SolveSpace version 3.0~ffd9c624., cannot make the centers of the two arcs coincident using constraints of points coincident or lock where dropped, but can drag them onto each other. in the attached file

Please see the error message, which is sufficient to explain the problem you are having. Namely, the sketch is overconstrained, and removing any of the extraneous constraints it suggests would be sufficient.

Just had another try and realized that the problem is that constraining the second center point to a point is effectively two constraints, and constraining the center point to the horizontal line through the center works. The error message is slightly misleading, in that it listed all constraints on the model which defined is shape and symmetries are actually needed. Any chance of detecting this and suggesting which axis the poing is free to move in.

The easiest way to see what degrees of freedom a point has is just to drag it with the mouse, and see how it can move. The error message lists all constraints whose removal would fix the problem, since it doesn't know what behavior you intended.
