GGU-CAD: "Compress" menu item

In contrast to the menu item "Window/Zoom" objects can be enlarged or reduced using different zoom factors for the x- and y-directions. After selecting a window area and left-clicking, the objects within the window are first displayed in negative to indicate the objects to which the action applies. The "Compression factors" for the x- and y-directions are selected in the following dialog box. The compression axes run through the respective centres. The action can be undone using [Backspace].
