2D to 3D Polyline by Profile

This command converts a 2D polyline into a 3D polyline by using a reference polyline, centerline and cross slope. For each vertex on the polyline, the program locates the station and offset from the centerline and then elevation on the profile for that station. Then the vertex elevation is set from that profile elevation plus the cross slope multiplied by the offset. For example, this command can be used to elevate a polyline for edge of pavement at a -2% cross slope from a centerline and profile for the road centerline. To elevate a polyline that is along the profile alignment without an offset, the Profile To 3D Polyline command is more direct method.

There is an option to use a surface to set the elevations at the start and end vertices of the polyline.
