I have been asked to model a kerb and channel renewal, road remake 1m from kerb and channel, and grass berm 0.8m from there towards boundary. I have a cul-de-sac at one end of the road which complicates things. Given that the road is 8m wide I am envisioning running the (half) road centrelne 3m from the true centreline and run this (half) road around the cul-de-sac symilarly. Is this possible? I am not sure how to edit the available road profiles.
