I've got a corridor where I want to have an assembly following a gutter line alignment but referencing the road centerline elevation as an offset and elevation target. The problem is, I don't want the gutter line at my centerline elevation, but rather I wish to target the road centerline profile, and let the subassembly definitions set the other elevations (i.e. lane slopes at 2% to gutter, gutter slopes to curb, etc.). I can set my lane offset and elevation targets to look at the centerline alignment and profile of the road, but then the vertical baseline at my gutter line (dummy profile to build a corridor) pulls my assembly at the gutterl ine. I'm just really unsure of how to do this and I'm hoping there's some trick with marked points or offset assemblies that would allow this. I tried shooting my assmebly from the road centerline to the gutter line, but my curb/gutter/sidewalk get funky as they're not perpendicular to my desired gutter line.
I've attached some photos to help visualize the problem.
- 'road plan.png' is a sketch of how my curb lines vary from the road centerline.
- 'assembly.png' is what I'm using and shows the gutter line reference point.
- 'example of bad x-sec.png' is what happens currently. My lane looks for the centerline elevation, but if I change the gutter line profile, it pulls the assmebly up to that point.
