Top-Tip: How to edit a Parameter AND Cycle the Model.

If you want to edit a design parameter in a dialog-box and also cycle the model:

1.Click the element you want to edit so it shows in the Selection-Window - e.g. a Gearing FB
2.Click Cycle

The element should still be in the Selection-Window

Now you can edit the elements as the model cycles.

3.Right-click the element in the Selection-Window
4.Select Edit element from the contextual-menu

Edit any parameter in the dialog as the model cycles.
