I have looked and looked and cannot find how to do this.With a dynamic block, I would like to stretch in the X in one visibility state, and have it stretch that same distance in the Y in another visibility state.  For example, a cabinet that has a vertical section in one visibility state with a stretch parameter in the X for the depth.  When changing that depth, the plan section in another visibility state, which has it's depth in the Y direction, will also change.  AND, the other way around as well.  That is to say if you change the plan section in the Y, the vertical section in the X will also change.I have been looking at chains and lookups, but cannot see that these will work.  Or if so, how.And help would be greatly appreciated.

Never mind.  Found the answer.  It is two stretch action on one parameter.  Change the angle offset on one of them.
