Overview

INTEL
Function Use to calculate the Intermediate (INT) Elevation of a point on a line/grade (e.g. sewer).
Also provides the slope for the line/grade.
Where:
EL1 = Elevation of Point 1
STA1 = Station of Point 1
EL2 = Elevation of Point 2
STA2 = Station of Point 2
STAINT = Station of Intermediate Point
ELINT = Elevation of Intermediate Point
SLOPE Slope between Points 1 & 2
