Host the MR to a Ref. Line Work Plane. Align and Lock one end of the RL to the x/y intersection of the 2 Ref. Planes. Pull an Angled Dimension between the RL and the x RP and label it with a Parameter. Enter the Angle value in the Parameter Field.


...order of operation is to place and lock the Ref. Line into place first, pull the labeled dimension, and then draw the Masking Region on top of the Ref. Line Work Plane. Align and lock the MR to the RL.
