I would like to see a routine that makes it easier to define a Cul-de-sac and Knuckles. I our case, a knuckle has a 12' offset crown that has a varying slope to the crown. Side slopes are either 1.8% or 2.0% and through the knuckle they change from the centerline to the crown. At 1/4 delta points along the centerline, the slopes from CL to crown are 1.0%, 1.5%, 2.0%, 1.5% and 1.0% respectively. I know I can define the transitions and force the crown to move over. But it would be nice to define a "Style" for each and simply apply that to the Object. Now you have to define a separate alignment in order to get the DTM to work, make sure you have your breaklines defined, and in the case of a CDS, "sweep" the section around the cul de sac in order for the surface to be correct.
