You can create baselines, which are reference lines from a baseline start point and a baseline end point.
You can create or list points in respect to the defined baseline. The Inverse Point command determines the station and offset distance of an existing point, or group of points, from an existing baseline. The Station/Offset command creates a new point using a station and an offset distance in reference to an existing baseline. Before you can use the Inverse Point, or the Station/Offset commands, you must define the current baseline. If you haven't defined the baseline and you select one of these commands, you are prompted to define the baseline.
