Hello, I am using AutoCAD C3D 2010. I am looking for a way to have my roadway lane sub-assembly target a vertical profile along a curb but stop at planter curb while still getting the slope as if it reached the farther curb. My situation is that another firm is designing a light rail alignment down an existing road with ballast curb. I have created an alignment and profile along their ballast curb which gives me a target with required curb exposure. I also have a curb and gutter along the outer edge of my roadway with an alignment and profile that I control relative to the existing conditions.
The light rail alignment is the base line for my corridor. My curb and gutter is at a variable distance from the rail ballast curb. My challenge really comes from the fact that I need to sometimes model a planter curb at a variable distance from the ballast curb. I want my roadway slope to be from my curb and gutter to the ballast curb as if the planter curb is not there. If I create a width target along the planter curb to stop my roadway, the elevation target of the profile along the ballast curb is projected to the planter curb making my roadway slope steeper. (See pdf) Is there a way with C3D 2010 to have the roadway slope shoot through the planter curb to the ballast curb?
