TML - Compute Elev Diff To Corridor

Blog Post created by Gary Lantaff on Jan 14, 2020

This macro will compute the elevation difference between each point in a linestring and the computed elevation of a specified corridor. The elevation differences are used to create a polyline in the profile view of the corridors alignment. A vertical offset can be applied.

 

This macro is handy when doing pavement resurfacing. The computed lines would then show the difference between the surveyed location and the design elevation at each station. From there you can then easily see in the profile view where you have to make vertical adjustments. After adjusting the template or the vertical alignment, then delete the old computed lines and run the TML again.
