How to create corridor material layers from designer provided roadway breaklines

Question asked by Devin Rogers on Oct 11, 2019

If we have designer provided breaklines for finish grade and all subgrade layers, is there a workflow that would allow us to use the corridor commands and material layers to perform a volume takeoff on those subgrade layers? We are specifically looking for a solution to quantify the "daylight" portions of those subgrade layers, which extend out to existing ground on the sideslopes. We can't quantify these sections using the typical surface to surface reports or via subgrade adjustments due to the trapezoidal/triangular shape of the section. We are hoping to use the corridor module with designer provided breaklines in a way that doesn't require rebuilding the corridor instructions from scratch. Thanks in advance!
