Breaklines, Part 5 - Enforce Varying Elevation

Published On: August 20, 2013

 

In the last edition of LP360 News, we discussed the creation of 3D breaklines for enforcing situations where the elevation must be a constant along the breakline. The most common example of this applications is "water body flattening" such as lakes and ponds. In this final installment of the breakline series, we will consider the case of varying elevation along the breakline.

Recall that, for our purposes, a 3D breakline is a vector that has an elevation value (Z) associated with each vertex. Generally, 3D breaklines can be divided into two categories - those with the same elevation for each vertex (used for flat water bodies, for example) and those with the ability to store a different elevation value for each vertex (a down-stream flow polyline, for example).
