We work on landfills that need stormwater control terraces and letdowns. It occurred to me to ask if there is some way to modify the water drop trace function (which examines a surface and determines the 90 degree to contours path) so that you could specify an angle to the contours of your choice. This would basically automate finding the flow path of a diversion berm. Maybe someone already has a method of laying out, for instance a 2% flowline along a 3to1 slope or tougher yet, a face with variable slopes.
Thanks for your consideration,
I also think that a command that would create a 3d polyline along a surface at a specified slope would be useful for creating a diversion ditch or berm.
There is a similar command in Carlson Civil... http://files.carlsonsw.com/mirror/manuals/Carlson_
Does anyone know of a Civil3D command to accomplish this?
