To create a 3D node in absolute coordinates, use of the option:
<A> Construct 3D node in absolute coordinates
Upon selecting this mode, the property window displays a dialog box for defining absolute coordinates of the node. Simultaneously, a coordinate system-shaped dragger appears in the 3D scene. The dragger coordinate system origin is placed at the point (0,0,0) in the world coordinates. The dragger axis directions coincide with the directions of axes of the world coordinate system. The position of the node being created is defined either directly in the 3D scene by the dragger, or by entering the exact coordinate values in the section "Coordinates" of the property window. To quickly reject the specified position of the node, use the following additional automenu option:
<Z> Move Node to coordinate system origin
