I recently completed the "Editing 3D Features Using ArcGIS Pro" webcourse. During the training I edited the soil/bench feature classes using the height field. By adjusting the height field the feature classes would grow taller or shorter (similar to what you would expect using extrusion).
My question is, how do I get similar functionality with my own polygon feature classes? The tutorial was great at showing me software capability, but I have no idea how to apply these concepts to my own data. I've spent several hours trying to solve this; I'm out of ideas (and new to 3D editing).
