∆∆
∆∆
∆Catch Offs : This value is where the pole is in
relation to where the existing ground
intersects the design slope of the
template.
∆∆
∆∆
∆Catch HgtD : This value is the vertical difference
from the ground shot to where the
existing ground catches the template.
∆∆
∆∆
∆Hinge Offs : This is the horizontal distance from
the prism to where the template begins
the slope (hinges).
∆∆
∆∆
∆Hinge HgtD : The vertical difference between the
ground shot and the hinge point.
∆∆
∆∆
∆CL Offset : The horizontal distance from the
ground shot to the centerline.
∆∆
∆∆
∆CL HgtDiff : The vertical distance from the ground
shot to the centerline.
The following illustration represents the various
components of the REFPT option.
