Polyline by Slope Ratio

This command allows you to draw or revise a polyline by specifying distance and slope ratio, percent of grade or pick points on the screen. The polyline could represent a section or profile which can be processed with the Polylines End Area or Sections from Polyline.

End/Percent slope/<Slope Ratio (?:1) <2.0>>: 5 This enters a slope ratio of 5 to 1 for 130 feet to the right of the starting point.
Undo/End/switch to Left/Pick point/<Enter Right Distance>: L
Undo/End/Pick Point/<Enter Left Distance>: 110
End/Percent slope/<Slope Ratio (?:1) <2.0>>: P
Percent of grade slope: 2 This enters a slope of 2 in 100 for a distance of 110 feet to the left of the starting point.
