GGU-CAD: "Select layer" menu item

This menu item allows the active drawing layer (= active layer) and the required visualisation layers to be selected. Alternatively, the visualisation layers can also be selected in the popup dialog by right-clicking. If the drawing objects are distributed across a number of layers, things may be clearer if only the active layer is visible and the other visualisation layers are hidden.

The next drawing layer can also be reached using [F11] or one layer higher or lower using [F12], or use the icons in the toolbar. Hidden visualisation layers are automatically revealed again if the layer is selected and it then becomes the active drawing layer.
