[SS4] Color coded slopes in SS4


Any pointers on how to create colour-coded slopes in PowerCivil SS4?

Currently I am trying to optimize the slopes on a railway platform, however, it is very time-consuming exporting my surface as a DTM, importing the DTM in InRoads and showing colour-coded elevations with the good old InRoads command. Surely there must be a smarter way as it is an iterative design process. 

Thank you for your feedback
