Enabling Subnodes
                                                        Disabled subnodes are invisible. To make them visible again, you can enable them in the 3D Graph view.
- In the 3D Graph view, select one or several disabled subnodes. Disabled subnodes will display in dark red, and their children will display in dark grey.
 
                                                                        
                                                                    
- Do one of the following:
 -  In the 3D Graph view toolbar, click on the Enable Subnode 
button.
 - Open the 3D Graph view menu 
and select Subnodes > Enable.
 
The subnode and its children are enabled.
                                                                        
                                                                    
In the Camera or Perspective view the corresponding 3D model part is displayed.
