I am working on a large corridor (about 2 miles) with several intersections and different sections. I would call it a complex corridor. For the most part everything is performing well and I am using the latest build of Civil 3D 2022. All the intersections are created manually using targets and several assemblies.
The problem I am having is occurring on the main line through the intersection. Several (but not all) of the intersections have strange anomalies with contours in the middle of the intersection. The assembly through the middle of the intersection is very basic and often is just two subassemblies (LaneSuperelevationAOR left and right). The subassembly has a 2% cross slope and no supers through the intersections. The edge of travelway is being extracted and used for a target for the curb returns outside of the main corridor. Here is what I would expect for the mainline through the intersection:
The above intersection gives a very nice "v" contour and has no change until after the edge of travelway.
Here is a small anomoly:
And then here are a few intersections that get worst:
Everything circled in yellow is confusing me and I have no idea how a constant 2% cross slope on a corridor can be influenced by things beyond the edge of the corridor. These are small anomalies and when I turn on points and tin lines for the top surface I can only see a few tenths of a foot in the worst locations.
If anyone has any insight as to why this would be happening I would really appreciate it. I cannot rebuild the corridor as it has been in design for almost 2 years and we are just finishing up the project on a tight timeline. Unfortunately, we need to provide a finish surface to contractors to bid the project and I want to get it as "right" as possible. Thanks in advance and let me know if there is any other info I can provide.
