Geopak PowerCivil Roadway Tool

Again, I'm fairly new to the Powercivil world but have been using Microstation for 7 years and used Civil3D sparingly prior to returning the Bentley products. We're running a test roadway tool exercise to determine how to design a single road "corridor" and have PC grade the existing site. We've built the tin, created the chain, cut the profile, edited the design profile using vertical design tools but I can't seem to apply the roadway configuration to the base surface in order to modify the grading. Has anyone else come across this seemingly rudimentary lack of results? Matt PowerCivil 08.11.07.614
