I have a template which builds a gore area with a V-Ditch / Variable ditch between a loop ramp and mainline highway. The template attaches itself to the edge of pavement of each backbone surface for the mainline and loop ramp and creates a ditch in between them with defined slope values. As the template can only be attributed to one alignment (either the mainline or loop) it attaches itself to the other alignment at a skewed angle (not perpendicular). When cutting cross sections values come out skewed (ie: not exactly 25%/4:1 slopes) due to diverging horizontal/vertical alignments. I am trying to get the template/corridor to turn at the V-ditch or variable ditch feature as a secondary alignment so it attaches to both backbones (loop and mainline) at perpendicular angles. The secondary alignment toggle in point controls does not work because my template is encompassed between two existing surfaces/corridors. This toggle only works when you are building outwards and have something defined to attach to (which is not the case with my V-ditch). I have also been playing with the secondary alignments drop down option from corridor in the roadway modeller. I am able to define a secondary alignment point based on station/offset inputs but it requires iterations and never quite works properly. If anyone could shed some light on this issue it would be greatly appreciated. -Thanks
