Hello. I am starting to model a fairly complex corridor I am trying to see if I can get away with using the stock subassemblies. I need the ability to control lane and material width(asphalt and sub bases step out further then the FP) as well the ability to control inner ands outer sub grade material height (at times sub grade follows FP with a crown, others I need to be able to run a constant 2% towards an under-drain or daylight). The stock "Lane Super Multi Layer" seems to satisfy my second problem, and "Lane Super Layer Varying Width" solves my first problem. Does anyone see a way this is possible with the stock catalog, or will I need a custom subassembly built? Thanks for any input.
