I have come to use the Create Side Slope command at lot in my corridor models, especially when I have to deal with intersections and ramps thus turning them into a site model. It would be nice if Create Side Slope maintained the structure of the Master Line i.e. the created parallel lines maintained the the curve data of the original line, and populated the elevation in the vertical tab of the line string. This would aid in maintain consistency and control of the triangle density when using the lines to generate a surface.
