As you can see, this is a very large kettle - 7.5 litres should begood for an excellent tea break in the staff room, but wedactually like 8 litres to keep all the staff happy.

28. Click on the green tick to record the measurement and closethe dialogs.

29. We can use Pro/ENGINEER to optimise this volume to anyvalue we require: select AnalysisFeasibility/Optimisationand choose Feasibility from the Study Types, then click Addunder Design Constraints, and enter as shown then click OK

30. Lets increase the accuracy of the calculation selectOptions Preferences Run, and change the Convergence %to 0.001.

31. Now click Compute to find the feasible solution.

32. To check the actual volume, Close the optimisation form,and Edit Definition on the Volume analysis feature, by selectingit in the model tree and holding down the right hand mousebutton to Edit Definition

As you can see, the new kettle volume is exactly as required.

As a challenge, see if you can create a new datum plane whichrepresents the fill level for four litres.

Obviously, this isnt the actual kettle volume, as this should takeaccount of the wall thickness, and the element etc. inside the

kettle, but this exercise was intended only as an overview.
