I want to extract them back out to an alignment with profile to create special ditches. What is the best way to get that information?
Try the offset tools under horizontal geometry I have used the offset tools to create point control alignments for corridors etc.. Should be able report on the geometry. May need to create direct offset from control line instead of corridor feature. Then set your corridor as active profile for the feature.
It says it's not a valid object to offset. I've tried copying it as well.
