Inverse Point to Line
Inverse Point to Line.
The Inverse Point to Line screen computes the perpendicular offset
distance and direction from a known point to a continuous line
defined by two points or one point and a direction.
Inverse Point: is the known point that the
offset information to a specified line is
computed.
Begin Station: is the beginning station value
that corresponds with the Start of Line, which is
used to compute the inverse station in the
results.
Start of Line: is the first point that defines the
line from which the offset is computed.
Point / Direction : is the second point or
known direction that defines the line from
which the offset is computed.
; Store Point: When checked, will store the coordinates for the point
located on the specified line, tangent to the offset.
Solve : will compute the distance and direction of the offset from the
known point perpendicular to the specified line.
Results
Inv. Station: is the station on the specified line where the
perpendicular offset occurs, starting from the Begin Station.
Offset: is the horizontal distance of the perpendicular offset between
the Inverse point and specified line.
Offset is: indicates if the Inverse point is located to the Right, Left, or
on the specified line as you occupy Point 1 and face the second point or
direction of the line.
Azimuth (pt to line): is the azimuth of the offset from the Inverse
point toward the specified line.
