Projecting Lines off a plane

[[An...]]

I have two measured planes. I need to create projection lines in the X and Y directions on each plane so I can compare their angles. How do I do this?

If you need just angles of each plane, then you can report just angle ( using A1 and A2 )

If you need angle between two planes, then you can use angle between features.

If any of previous doesn't fit your needs, then make theoretical plane in needed vector and intersect this theoretical plane with your feature to obtain a line.

Similar is projection of feature onto theoretical plane.
