Option Switch 20 works in conjunction with Option Switch 19 to set the cut-off value that determines the steepness of slope that should be shown as a fall. In the following example, the cut-off value for the pipeline is set to 5-degrees.
In the next illustration, the cut-off value for the same pipeline is set to 4-degrees. Because the actual slope is now steeper than the cut-off value, the slope is shown as follows:
