I am creating a surface in Roadway Designer and when I run the surface the Tin that is automatically created will draw down to the bottom surface of the road base at certain points and then jump back up to the top surface of the road and it zig zags like this all the way across the road surface.
For example, the tin surface will go from the top edge of the median barrier to the bottom of the base at the left shoulder, then to the top of the road at the crown point and then back to the bottom of the base at the right shoulder. This just started happening to my model after having no problems.
When I add transverse features to the surface it also follows the same points that the proposed tin is following.
Does anyone have any ideas why this is happening? Thanks!!
