Add Spirals to Civil 3D Alignment Part 1 of 4

In this video we are going to see how to add spiral curves to Civil 3D Alignment.

"Various transition curves are used in civil engineering to gradually introduce curvature and superelevation between both tangents and circular curves as well as between two circular curves with different curvature.

Add floating curves with spirals in situations where you need a transition spiral and the curve geometry must pass through a specified point.
Add floating lines with spirals in situations where you need a spiral transition to a line that is defined by either a pass-through point or length."
