point names.

[Solve]: will compute the distance and direction of the offset from the known point perpendicular to the polyline.

Note: There is no solution if a perpendicular offset does not occur within the extents of any selected polyline
segments.

Results

Station: is the station along the polyline where the offset occurs, starting from the Begin station.

Offset: is the horizontal distance of the offset.

Offset is: indicates if the Inverse Point is located to the right, left, or on the specified line as you occupy the beginning
of the polyline and face the end.

Segment Type: shows if the segment is a line, arc, or spiral.

Beg. Pt: if applicable, this is the first point selected that defines a line.

End Pt: if applicable, this is the second point selected that defines a line.

Inverse Point to Multiple Points

[Inverse] [Multiple Points]

The Inverse Point to Multiple Points screen will calculate the distance and direction from an existing point to one or
more other points.

Inverse point: is the reference point used to compute the distance and direction to the other points.

[Tap Points]: provides a map view where you can tap multiple points.

[To/From]: provides selection of points by point name.

[Solve]: will compute the distance and direction from the Inverse point to all selected points.

Results

Azimuth: is the azimuth from the Inverse Point to the selected point.

Horz Dist: is the horizontal distance from the Inverse Point to the selected point.

Vert Dist: is the vertical distance from the Inverse Point to the selected point.

Slope Dist: is the slope distance from the Inverse Point to the selected point.

North: is the change in the Y-coordinate from the Inverse Point to the selected point.

East: is the change in the X-coordinate from the Inverse Point to the selected point.
