My design is a parking loop road. I made a preliminary Corridor that runs a pavement only template along a Centerline Profile, with Parametric Constraints to control slopes and widths so this corridor can define my pavement slopes. Next, I created an Civil Geometry Alignment that follows along the gutter pan of the parking area.
To avoid any dependency issues, I exported that corridors terrain to a DTM, and deleted the terrain element before re-importing the DTM from InRoads.
I then created a Quick Profile from Surface for the gutter pan alignment and made it the active profile. I then set this profile as the profile for the gutter pan corridor.
I now try to add the features from this corridor to another Terrain element and get this dialog box:
How can this even be a circular dependency?
