Chris,
We have performed numerous workshops and online seminars that cover this very topic. Have you checked our online library?

Thanks Thomas. Yes, the library helps. In hindsight, I realized my question was a little too general, since different DOT's design the ramp horiz./vert geometry slightly different. With components, it changes the ramp modeling practice a little from before.
There may already be a CR for it, but are you guys considering the possibility of having 3d component editing tools (like with features) instead of being completely reliant on the RD?
We are always progressing with a logical approach to 3D modeling. Instead of discarding completely workflows and data, Bentley is taking an evolutionary approach to our progession of the software solutions.
This maintains the integrity and forward compatibility of legacy data and provide value for your maintanence.
You might want to visit MD SHA's CADD Standards web page - within their data is a training data set for the Roadway Designer. They do some interesting things with TC points. Also, I had received a data set from a gentleman at Vermont's AOT where they modeled a roundabout in Roadway Designer. There is a number of very intricate design possibilities within these tools that make gore and intersection cleanup almost automatic.
People found ways to do very creative thing with the Roadway Modeler - given time, the same will occur with the Roadway Designer.
I'm not sure if I have the roundabout data set anymore, but on their web site is a document on intersection design that I believe actually explains many of the techniques used in the roundabout example.
