If a graphObject is selected in the explorer the attribute editor shows two Buttons that allow to access the 3d and 2d view of the Graph Object. While it is possible to manipulate the imported structure using these views the changes can not be stored and will be removed when the project is reloaded.

It is also possible to call the view2d and view3d function from RGG:

    public void run ()
    {
    graphobject("toto3.qsm").view2d();
    }
