Creating Design Profiles

Earlier, you used a surface profile to determine the nature of the existing terrain along the path of Jordan Court. As the surface profile shows, the current state of this path is not suitable for driving, so it must be transformed into something with much more subtle geometry. In other words, a new profile must be designed for the road. In Civil 3D, this type of profile is often referred to as a design profile or layout profile.

Like alignments, design profiles consist of straight line segments (called tangents) and the curves that connect them. The curve geometry is a bit different but, essentially, you can think of ...
