I'm working on my first AIM project. I'm trying to adjust elevations on a coverage area where we are proposing work, but when I do that, the existing terrain is adjusting in areas that I need to hold the existing conditions. Is there any way to create a coverage area over the existing conditions that I need to hold, and lock them, so that AIM only adjusts the terrain outside of that area? If not, is there anything else I can do to control how AIM is modifying my terrain in this situation?
