Mini-CAD: Layer operations

The following options are available in the "Layer operations" group box:

• "Statistics"
  A dialog box opens displaying the total number of objects in the individual layers. The buttons of layers containing objects are active and can be clicked. A message box opens listing the objects by object type and the respective number of each type.

• "Reduce"
  The objects on all layers can be moved to a layer selected in a dialog box. This operation cannot be undone. You should therefore save your Mini-CAD data to a file before commencing (see also “Deleting/saving/loading Mini-CAD objects/Saving Mini-CAD objects”).

• "Delete"
  All objects on one or more selected layers can be deleted.

• "Select"
  Selected object types on a selected layer or on all layers can be marked for certain operations.

• "Load"
  Objects from a Mini-CAD file of the same CAD type can be loaded into a selected layer in addition to the existing objects. If you click the "New" button, the existing objects are deleted from this layer; they are supplemented using the "Append" button. Any distribution among the layers in the appended Mini-CAD file is not taken into consideration; all objects are loaded into the selected layer.

• "Save"
  All objects of a selected layer can be saved to a Mini-CAD file using the ".mcd" or ".kpf" file extension, depending on the selected CAD type.

• "Sequence"
  Mini-CAD objects are displayed in the sequence they were created in. Using this button all objects in a selected layer can be moved either in front of ("To front" button) or behind all other objects ("To back" button). All objects in a selected layer can also be moved to a different layer (also see Sections “Displacing/moving Mini-CAD objects/Changing sequence of visualisation/Move all objects on a layer” and “Displacing/moving Mini-CAD objects/Changing layer allocations”).

• "Visualisation"
  By default, the Mini-CAD objects used in GGU programs are drawn over the graphics of the respective GGU program. This means that some regions of the result graphics or legends may be covered by the Mini-CAD objects. In this button's dialog box you can choose to display objects behind the graphics of the respective GGU program. Simply deactivate the check box for required layer (see also “Displacing/moving Mini-CAD objects/Changing sequence of visualisation/Changing the sequence of Mini-CAD objects/program graphics”).

• "Reverse selection"
  If certain object types have been marked suing the "Select" button, the selection can be quickly reversed using this button and the previously unmarked objects be selected.

• "Hide/unhide"
  To improve clarity when using a large number of Mini-CAD objects it is possible to hide selected drawing layers. To do this, remove the ticks in the boxes for the respective layer. Using the buttons in the dialog box's lower group box all layers can be hidden or unhidden simultaneously, or a selection reversed.
