Hi.
I'm unable to find a topic on following issue, which seems to be quite easy, but...I'm designing in OpenRoads and in template there is a simple gravel layer - 20 cm high with rooftop type crosslopes - 4% each. As I create the superelevation, for example, for surface left edge, to elevate and in full superelevation I have onesided crosslope (4%), the left side's subrgade line still is rooftop type - 4% each. How do I make the subgrade line to follow surfaces left edge? I would like it to follow as red line in the sketch.
Thanks.
Constraining your subgrade points to the surface points (which are controlled by the superelevation point control) should make it work. For example, a subgrade point would be constrained horizontal = 0 and vertical = subgrade depth.
