One of the following conditions exist:
The points do not define the feature (circle, line in the working plane, line in space, or a plane).
The features do not define an offset angle.
Either the line is perpendicular to the measurement plane, or the points are equal when projected onto the measurement plane. The offset angle is not changed.
The features are parallel.
The features are perpendicular.
The features are identical.
As a result, the command is not executed.
You should check the command's definition and correct the measurement routine.
