If a point exists and you try to save another point with the same name, a dialog displays a prompt that the point already exists.
The Don't ask in this session check box is enabled when you selected the Store as check point check box. If the Don't ask in this session box is checked, MAGNET Field will not display the Point Check dialog during current session; on attempt to store a point with the name that already exists, the point will be stored as the check point for existing point.
The Correct Base check box is displayed and enabled, when:
The Correct Base option allows you to correct the existing Base coordinates or obtain a new Base coordinates, when the Base is installed at an imprecise position. The known coordinates of the existing point are not replaced by the measured coordinates, and they are used to correct or calculate the current coordinates of the Base station. The Raw Data dialog displays such Base station as "*Ph. Center Coords (Corrected)".
When the user closes the Topo dialog, the application recomputes the coordinates of all points using the new Base coordinates.
