Geometry
, create a new relation:B_Frame = 2 * B * Rel_B
The The dimension of B_Frame
is meters (m).
This function states that the width of the ship at a certain frame number equals the relative width at that frame number multiplied with the total width of the ship. Notice that the frame number is no direct input in this relation, but Quaestor will still ask for it in a solution as Rel_B depends on that parameter.
We'll use an alternative way of creating solutions. First we will add some attributes to the Ships Ships
object. Attributes are used to direct the behaviour of Quaestor in solutions. All available attributes are described here. We will apply two attributes: @DBENTRY and @DBOBJECT.

Attributes are either separated
See figure 8.
Attributes are either separated by a space or by a hard return, not by a comma. The meaning of the entered attributes will be explained at the end of this tutorial.

The main procedure to create solutions with an existing dataset is through the use of the Process Manager. In the Process Manager, datasets and top goals can be selected to create new solutions. Furthermore, existing solutions, macros or scenarios (these terms will be explained in another tutorial) can be restarted. First, we'll make sure our top goal B_Frame
can be selected in the Process Manager.
In the Knowledge Browser, drag the parameter B_Frame
to the class Top Goals/Undefined.

Parameters can always be exchanged between classes, there is no influence on the behaviour of Quaestor except that parameters in the Top Goals/Undefined class are visible in the process manager. |

The Process Manager starts (figure 10). The left hand side shows all available datasets, in this case only our Ships Ships
object. The right hand side shows the available tasks. The parameters in the Top Goals class are shown here, as well as existing solutions. A combination of a dataset and a task results in a solution.
