Stepped Offset

Is there a command similar to stepped offset in Civils 3D. Whereby you can offset a open or close curve along a vector or grade / percentage slope offsetting in both horizontal and vertical directions at the same time. I know this can be done by extruding curve in a modified cplan direction and trimming to a target surface to create the daylighting. I think this would be an easy feature for McNeel to have if it hasn’t already been developed in GH.

Hi Daniel- I am pretty sure GH could be coaxed into doing this -have you tried that? how would you want to specify slope? %? Degrees?


Would Shear be useful for this?
