    Default Targeting Vertical before Horizontal

    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?

    Earlier in your assembly add a Link With and Slope assembly,

    Then in your assembly parameters you will see those boxes that say USE
    tell that curb or pavement assembly to GO Get the Elevation of the LWS ssembly that is targeting that Farther curb alignment or profile.

    I thank you for your suggestion but I found that your method still gives me the same result (at least in 2010).

    With some help I found that I could use a GenericPavementStructure and get my default slope from its cross slope output parameter.

    Thanks for your help.

    Happy to help, the concept was the important part, not the actual assembly being used.
    You will find that some assemblies offer more of themselves than others for these purposes.
