no matter where I place the 0.67' cross dZ rule, it raises the back of curb 0.95 at inside corners (only). It appears the rest of the curb is correct at 0.67' beyond the closest vertices to the inside corners. I've noticed this at several areas in the project. The magenta line is locked and elevated. The green line is undefined. Both are part of the Vertical Design and a alternate surface. Also note that many of the inside corners do model correctly. Please advise.
