The Data menu contains commands for calculating and changing the numerical data, which defines the design.

The Units command allows you to set the dimension and weight units.

This menu function allows you to precisely specify positions for all Sections, Waterlines, Buttocks, and Diagonals..

Choosing this function allows you to set the positions of the Fore and After Perpendiculars,  the DWL and the Baseline of the design; the Midships position is altered indirectly since it is assumed to be mid way between the Fore and After Perpendiculars. All values are entered relative to the Zero Point.  However, it may be that the Zero Point is set to the position of one of the elements in the Frame of Reference.  In this case the Zero Point is not updated until you have clicked OK in the Frame of Reference dialog.

This function sets the longitudinal and vertical reference point for all measurements.

Allows the user to select the precision (point density) that should be used for the Shipflow export and other export formats where the precision is not automatically set.
