I'm trying to create a graded area around a pad. I create the horizontal geometry (square) and then use Complex Geometry to unify the lines into a single element. I create the concrete pad first, without issues, and the vertical profile is generated again, without any problems. However, I want to create the vertical profile of the surrounding grade by reference to the pad at a -1.00% slope. I used "Profile By Slope from Element." After completing the prompts, the profile of the grade is generated but there is always a "piece" of the geometry left out of the vertical profile, while no apparent break in the horizontal profile exists.
