R-357
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.
