GGU-3D-TRANSIENT: "Draw Mini-CAD elements first" menu item
Originally, the display sequence could be modified using this menu item. In the program's default settings Mini-CAD objects are above system graphics; they may therefore cover it.
In Version 7 of the integrated Mini-CAD module you can now work on a total 20 different layers. To move Mini-CAD objects behind the main program system graphics click the "Layers" icon
