Specifies the minimal slope value for the pipe run. You can specify the slope as a ratio, a percentage, or in degrees.
ratio
If a run drops 1/4" for every foot of horizontal distance, specify the slope as 1/4"/1'-0".
percentage
If a run drops 1" for every 10" of horizontal distance, specify the slope as 10%.
degrees
A five-degree slope can be specified as 5deg.
When routing a sloped pipe, use a slope value that is larger than the Minimum Slope for the pipe run to avoid Invalid Slope Angle To-Do-Record (TDR). The software compares design slope and minimum slope of the pipe
run. If there is a difference between the values caused by any modification, the software
generates a TDR.
