2D to 3D Polyline by Slope From Reference

This command converts a 2D polyline into a 3D polyline using a slope from a reference 3D polyline or point. For example, this command can be used to elevate a bottom-of-bank polyline given an elevated top-of-bank polyline and bank slope. After selecting the polyline to elevate and the 3D reference, there is a prompt for the slope percent. Use negative for downhill. For each vertex on the 2D polyline, the program finds the nearest position on the 3D reference and assigns the vertex elevation using this reference position elevation plus the slope multiplied by the distance from the vertex to the reference.
