This command checks 3D polylines to make sure slopes are within the specified range. For any segment that is outside the range, the program will set the elevation of the polyline vertex to put the segment with range. This routine could be used on a 3D polyline for a ditch to make sure the slope has a minimum grade. Also this routine applies to a 3D polyline for a road that has a maximum grade.
All slopes up, down or either
[Up/Down/<Either>]? U for up
Min slope percent: 1
Max slope percent: 9
