Hi Everyone,
I have been trying to set up a generic assembly for applying to future river design projects, but am having issues with some of the finer details involved with surface generation.
To describe my problem briefly, I am trying to make an assembly follow the centerline of the valley corridor, and meet targets for the channel bottom of banks and top of banks, the toe of valley slope, and finally grading the valley side slopes up to an existing surface. This is shown in LAYOUT.jpg. Once I have input all of the appropriate profiles for each of the features, I model the corridor using the Valley Centerline Alignment, with a profile representing the center of the valley, which ignores the channel itself as it crosses accross this centerline.
The issue is that the channel 'breaks' as it crosses the valley centerline, as shown in SURFACE.JPG.
Is there a solution to fix this problem, or a more effective way to model this corridor?
Additionally, I am having another issue with making the channel and valley line up appropriately. With the method of corridor building that I am currently using, the valley is fluctuating as the channel meanders accross the valley centerline (This can be seen in SURFACE.JPG). This is due to the 2% slope from the top of bank to the toe of valley slope (required for water drainage). The question I have for some more experienced channel and valley designers in Civil 3D is, is there a more effective way to model a valley and channel corridor without sacrificing the consistency of the valley floor/bottom, and the depth/shape of the channel itself?
Thank you all very much for any help, as it feels like I have been spinning my tires for quite some time now.

This is a Confirmed Defect. Dave Simeone told us he is working on it.
