Does anyone offset their VAL? I just had a thought as I am creating my VAL. "It would possibly make creating subgrade faster already having the roadway top node for the corridor or sideslope. SO, what would be a quick way to offset the VAL?
All I would do is offset the ALG 0.005 LT or RT. This will create a Line string. Change the elevation of the line to the VT offset for Subgrade then create a new alignment from that. This will give you a Subgrade Alignment.
