I've Been Experimenting Using Multiple Coordinate Systems At Different Elevations. While Using A Line, Curve, Or Whatever Command. Every Time I Try To Aline To The Different Coordinate System... I'm Coming Up With The Same Coordinate Plane.
Any Thought. On How To Use Multiple Plane At Different Elevations
Not sure what your use case is, as to why you need multiple coordinate systems.....but using reference planes is easy.
In Synchronous [which is what I think you're using mostly], it's as simple as placing a coincident plane based on one of the base [or existing user defined] planes....then once the steering wheel appears, reloacting [along or about the axis] it as desired.
