GGU-STABILITY: "Surface" menu item

With this menu item you can enter the system surface line via the mouse (see Worked example 1). The dialog box which appears explains the possibilities. This function can also be initialized pressing the [F3] function key.

If you activate the "Snap to current line ends" check box, crosshairs will be shown instead of the mouse cursor or, if you prefer, large crosshairs with an enveloping rectangle. If you have already made some input or Mini-CAD data (including those created with DXF import) are present, the program will snap on to the nearest point (if the point is within the rectangle) when you click the mouse. If, e.g., the system to be calculated exists as a DXF planning file, you can greatly simplify input.

This information is also valid for all the following sections which are concerned with system input with the mouse.
