Estimating Weight and CoG
3.8 Automatic Calculation of Weight Groups as
Percentage of other Weight Groups
In some cases it may be desirable to have a weight group calculate itself
automatically based on another weight group or based on several weight
groups. An example of this would be to have a margin group calculate its own
weight as 5 % of the lightship weight. This is possible to achieve by using the
Weight Group Percentage Setting dialog. This dialog is opened from
ShipWeight main window menu
Wgt.Grp->Percentage setting…
• Add a relationship between groups
Select the weight group to be automatically updated from the left drop
list in the dialog. Next to the drop list, type the percentage to be used
when calculating the weight automatically. Select the weight group
which value the calculation should be based upon from the drop list to
the right. Click the “Add” button to register the relationship. The
relationship will be listed in the list below.
• Delete a relationship between groups
Select the relationship to be deleted from the list. Click the “Delete”
button to remove the automatic calculation relationship. You may also
delete all defined relationships at once by clicking “Delete all” button.
• Edit a relationship between groups
Select the relationship to be edited from the list. Make the appropriate
changes in the drop lists and percentage field and click “Edit” button to
update
