Given the capability to do a One-Off Version of a WTPart, the same business need would be applicable for any Organization utilizing Associations between CAD and WTParts as well as the supporting Visualization. Except there is no capability (confirmed by Tech Support Call) to generate a One-Off CAD Version to correspond to a One-Off WTPart.
Please enable One-Off Versioning for CAD, in particular CAD that is associated to a WTPart that will have a One-Off Version generated.
P.S. - Can anyone suggest a Workaround unless/until this Idea grows legs?
