In this tutorial, we'll create the shape of a ship's waterline in a table of frame numbers and dimensionless widths. The dataset containing variations of the main dimensions of a ship from tutorial 1 is stored in a data object Ships in the dataset of the knowledge base, so it can be easily used in further calculations. This dataset combined with the dimensionless width table is used to calculate the width at the waterline at frame number 2 for every variation.

...

In this paragraph, an object is created that will be given contents later on. We will create the object Ships.

 In the knowledge browser, select the class Top Goals/Undefined. In the right hand side,  New Parameter/Function (or Ctrl+I). Name the Object Ships and select the type: Object.

 Unlike the Waterline object, which was defined by a function, the object Ships does not yet meet the validity conditions.

...

 In the Workbase, select the Dataset node. In the Knowledge Browser the object Ships and select Parameter to DataSet (or Ctrl+O), or drag the Ship object to the Dataset, see figure 7.

...

Our data object should contain all the ship variations produced in tutorial 1. Therefore, we will copy the results of the second DISPsolution (with the variations) to the object Ships using the clipboard.

  In the Workbase the second DISP solution and select All to clipboard (or press F4). The Clipboard window now pops up (figure 8). In the workbase, select the object Ships in the Dataset and press Paste in the Clipboard window. Quaestor will ask you if you want to copy the parameters, select Yes to all and continue.
