GUMBALL (OBJECT MANIPULATOR)
When selecting an object with your mouse an object manipulator will show. With this manipulator you can drag the object in X,Y or Z axis. Alternatively you can drag the selected object in one of the three planes or rotate around one of the world axis. For some supports nodes a purple arrow will show when selected; with this you can scale the support node at that point. Upon releasing the mouse the connected items will scale automatically.
