GGU-STABILITY: Step 3: Define array (Ex. 1)
Select the "Array" menu item from the "Editor 2" menu.

Activate the "Use array" check box. This ensures that the cross hairs snap onto these points during the following input with the mouse. This makes input of slope geometry easier. If you have a geometry which does not lend itself to being forced into such an array, do without activating the check box. Leave the dialog box with "OK". The array will be displayed after selecting one of the following menu items!
If you own a scanner, you can produce a bitmap file of the system to be processed. This bitmap file can be imported using "Graphics preferences/Mini-CAD toolbar" menu item (see the "Mini-CAD" manual). You can thus further simplify system input.
