    Default 3D Polyline Along a Surface

    Summary: Create a 3d polyline along a surface at any direction at a given slope

    Description: Create a 3d polyline along a surface at any direction at a given slope

    How Used: I would use like this..I have a surface of 3h:1v at extends 100' vertical. i would like to start at a given point at the base of said slope and project a 3% line up along said slope until it reaches the top of the surface. this line could be used as a feature line to do some additional grading or a boundary line (kinda much for a boundary but hey!!)

    Feature Affinity: Feature Lines

    i'm using 2013 C3D and you can already sample the elevations of a surface with a feature line which whould assign the slope of the surface to the feature line. it could then be extended and exploded to a 3d poly.
