Adding Lines, Curves, and Transitions to an Alignment

Topics in this section

About Adding Lines, Curves, and Transitions to Alignments
Use the constraint-based commands on the Alignment Layout Tools toolbar, to add a fixed element, a free element, or a floating element (lines, curves, transition-curve-transition groups and transitions) to the alignment.
About Tangency Constraints for Alignment Entities
This section contains tangency constraint descriptions of fixed, free, and floating alignment elements.

About Spiral Definitions
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.
