Procedure
Open the model for which you want to perform the layout generation.
Activate the Format tab bar.
Click Layout. The dialog opens. The layout procedure on which the current model is based is selected
by default.
Specify your settings. After each setting change, the model is re-arranged in the preview area. During the calculation process, (regenerating...) is displayed after Preview for your information.
Once you have specified the necessary settings, you can base future layout generations on the current layout procedure. To do this, enable the Use as default check box.
Click OK.
