Is it possible to have a closed alignment? i.e. i want to create a corridor for a small parking lot with a center island.
i plan to use a curb & gutter assembly around the island and the outer perimeter of the the parking area and create a corridor and top surface.
i will have an alignment around the perimeter and a separate alignment around the island.
I know in the newer versions, you can use a feature line as the baseline for a corridor.
