GGU-CAD: "Save individual layers" menu item
As an alternative to the "File/Save" menu item described above, the drawing elements of individual layers can be saved to separate files using this menu item in order to make certain layers (e.g. points on a site map) available for other files.
Click one of the buttons to save the elements in this layer to a file. The file extension is ".CAD". If no extension is specified, the program uses this extension automatically.
