    Default Constraints 2

    I am trying to check the rotational clearance of a brace and leg, so I have drawn a simple centreline of both components, fixed the main pivot point, place a coincident restraint at the next pivot point, and a sliding coincident restraint at the final point.
    It all worked first time but the geometry needed some adjustment. The leg refused to rotate back into the start position and when I removed the constraints Autocad will not re-apply them. I get a message saying
    Command: _GcCoincident
    Select first point or [Object/Autoconstrain] <Object>:
    Select second point or [Object] <Object>:
    The constraint cannot be applied. The two objects must reside in the same plane.
    All lines start and finish on Z axis 0 and the UCS has been placed on one of the lines so how are they not in the same plane and how were the constraints applied the first time?
    Is this an Autocad issue or am I doing something wrong?
    Can anyone help here?
