Additional groups can be added above the currently selected group in the table by clicking the Add button or pressing Alt+A. To add several groups, select the required number of rows. Groups are deleted by selecting the groups and clicking the Delete button or pressing Alt+D.

These enable saving and retrieving of the group settings from a file.

Shipflow offsets are exported in the currently selected units, unless non-dimensionalised. Use this checkbox to specify whether the output should be non-dimensionalised with respect to LPP.

Skin thickness can included by ticking the “Apply skin thickness” checkbox in the Group Definition dialog if it is projected outside (or on either side of) the NURB surface. Skin thickness will be included for all the groups when this option is selected.

Groups may be sorted by double clicking on the column you wish to sort by. Successive double click cycle through sort ascending, sort descending and unsorted.

The table supports full copy and paste capability. So you can store your group definitions in Microsoft Excel (for example, however ensure that the cells are formatted as text and not general otherwise the colour and surface selection data will become corrupted).

In addition the group definition is appended as comments to the end of the output Shipflow file (along with other relevant information). This facilitates regenerating the data if the model is updated or adjusting the groups.
