The solution is the object Waterline, which is filled with values for Rel_B  for every case of Frame. Please note that the parameters are requested in alphabetical order. By using the @ORDER attribute in the data slot of the parameters you can manipulate this order (provide @ORDER:1 to StartFrame, @ORDER:2 to FrameStep and @ORDER:3 to EndFrame). Furthermore, please note that you cannot select Waterline as top goal when you are into the Waterline object in one of the solutions. The reason is that Quaestor assumes you want to add a parameter to this level and does not allow you to do so.

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 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.
