With the two points method, you simply enter two point numbers, or choose them from the point list or MAP. The
azimuth and slope between the two points is calculated, along with the ending station, based on the entered start station.
With the Azimuth method, you define the line by entering a first point and then entering an azimuth and slope. You can
confirm the coordinate values of the points by choosing Confirm NEZ. When the line is defined, choose Continue.
You must now define, or designate, the point that is offset from the line in the Point Definition dialog.
You can enter a point ID, select one from the list, or select one from the map. You can also enter coordinates to define a
new point, or read values from the instrument. As soon as enough information is entered, the station, offset and vertical
difference is displayed or the message "OFF CENTERLINE" is displayed. This message lets you know that a
station/offset cannot be computed for the coordinates entered.
 Read
: This command reads the instrument to gather coordinates for point projection.
 Intersect
: This command will project the coordinates entered perpendicular, back to the centerline and enter these
new coordinates into the Point Projection dialog. From there you can store or stakeout the intersect points.
 Stake
: This command will allow you to stakeout the displayed coordinates (typically used to stakeout the intersect
points).
 Store
: Pressing Store after Read stores the offset coordinate. Store after Intersect is selected stores the
coordinates for the intersect point on the centerline (perpendicular from the offset point). Store after entering
coordinates or a point number for the offset point, without selecting Intersect, will simply store the offset point
coordinates again as a new point number. Store is most often used to save the calculated intersect points to the
coordinate file. Pressing Store will save an SP (store point) record in the raw file, and a note record will indicate
that the point was calculated within Point Projection.
Station Store
Station Store
is a pure calculation routine that will create points based on a station and offset from an alignment. The
