  In the class Geometry, create a new object called Hull. As we want to store static data in this object, make sure it is determined by Value from Object/Database (as described in tutorial 2). In the workbase, select the object Ships (under Dataset). In the Knowledge Browser, right click the parameter Hull and select Parameter to Dataset (or drag it tot Ship). When you are asked how to add Hull to the Ships object, select the list and continue. The new object is now placed within Ships.

First, we take a look at the arguments after Hull. Data within the object Hull will be used in the integration, but yet it only contains dimensionless frame numbers and dimensionless widths. By putting (@X, @B_Frame, Lpp, B) behind it, you ask Quaestor to calculate X and B_Frame using data from within Hull, using Lpp and B from outside Hull and add all these parameters to the object Hull. You do actually use the object Hull as a function to calculate other parameters. This is a very powerful ability of Quaestor (see also QuaestorSyntax).
