The Drape Alignment operation takes an Alignment/Super Alignment string and creates a new Alignment/Super Alignment string with identical horizontal geometry and the z-value for vertical intersection points taken from a tin. The z-values (IP Method) are taken over a user specified chainage interval and chainage increment. Vertical intersection points outside the chainage range can be kept.
The draped alignments can also have a z-offset applied so that the draped alignments are a constant distance above or below the tin.
For an example on the use of this option, please check out the short video below.
The panel can be found via: Tins => Drape => Alignment
