Constraint Conflicts

If you enter a constraint for some geometry which is already constrained by another constrained object you will see a message like the one below.

In this case, the Coordinate constraint was already determined by the other two sides and an angle constraint on the triangle. There are two ways of dealing with this problem:

1. Hit the Cancel button (or select the first option, "Discard the coordinate", and then click OK) to leave the drawing as it was without the new constraint.
2. Select the second option, "Create an annotation from the coordinate", and then click OK, the coordinate constraint become annotation coordinates. It just show on the diagram and has no effect on the geometry engine.
