Having used the Sketch Project Curve command to project the arc center of a hole in another part to a sketch, it is not possible to move the projected point. NX raises the message: "One or more constraints are violated with the selected motion type. Remove some constraints, change the motion type or change the object selection". How do you find and delete the constraints that are preventing the point from being moved?
Double-click the projected point and uncheck "Associative" from the Settings block of the dialog and OK the change. The point can then be moved.
