GGU-CAD: "General" menu item

Global default program settings can be made in this menu item. The following dialog box opens:

"Show info before calling certain menu items"
information on the functioning of the corresponding menu item is displayed by default for a number of important menu items. This is particularly useful during the familiarisation phase. The information can be deactivated or reactivated using this check box.

"Window size in pixels"
The size of the window can be defined for window operations (see Section "First steps/Windows" and the "Window" menu). This can also be more simply done by opening the popup dialog (right mouse click), clicking the "Define window size" button and then defining the size of the window by clicking the two corner points.

"Window acts on"
The window action for window operations can be specified. For example, if only the "Text" box is activated, all window operations (such as "Delete window", for example) act on texts only. Lines are not deleted in this case. This setting is also accessible via the popup dialog (right-click).

"Cross-hair length [pixels]"
The size of the screen cross-hairs can be altered. The default setting uses cross-hairs that extend to the screen boundaries.

"Snap radius [pixels]"
Here, the size of the so-called snap radius can be defined (dotted box around cross-hairs). A further description can be found in Section "First steps/Snap radius".

"Snap radius acts on"
The action of the snap radius can be defined. It s possible to restrict the action to the active layer (box has a dashed outline) are to extend it to all layers (box has a continuous line) or to turn it off completely. Activate the corresponding box. It is simpler to perform these settings in the popup dialog, which opens by right-clicking on the screen. In addition, the three different options are available by pressing "F" without opening this dialog box.

"Use array"
The cross-hairs will snap to the nearest array point when the mouse is clicked if a array in x- and y-direction is defined and the appropriate check box is activated. In addition, the two different options are available by pressing "R" without opening this dialog box.

"Always refresh"
If this check box is activated the drawing is always redrawn after changes are made. This may take some time for many types of objects. Deactivate this check box to increase processing speed. The disadvantage of this is that the screen contents do not always reflect the actual conditions. If necessary, go to the menu item "Graphics preferences/Refresh" or press [F2].

"Screen visualisation in cross-hair colours"
The option of screen visualisation in cross-hair colours simplifies visualisation when working in several layers, because then all objects are shown in the colour of the cross-hairs for the respective layer. The colours of the cross-hairs in the various layers are specified in the menu item "Preferences/Pen colour and width".

"Autosave after [minutes]"
The program saves the file at the specified intervals. The name and path of the recovery file can be read in "Info".

"Create BAK files"
If the generation of BAK files is also required, activate this check box.
