The following example is to demonstrate the rearranging of a normal 2D network for three dimensional display. As example network, the letter classifier LETTERS.NET is used.
In the 2D-display, the network looks like in figure 
:
One scales the net with scale 
in the transformation
panel, then it looks like figure (left). After a
rotation with rotate 
by 
around the
x-axis the network looks like figure (right).
Figure: Scaled network (left) and network rotated by 
(right)
Now the middle layer is selected in the 2D-display
(figure , left).
Figure: Selection of one layer (left) and assigning a z-value (right)
To assign the z-coordinate to the layer, the z-value entry in
the 3D-control panel is set to three. Then one moves the mouse into
the 2D-display and enters the key sequence "` U 3 Z"'. This is
shown in figure (right).
Figure: Selection of a reference unit (left) and moving a plane (right)
Now the reference unit must be selected (figure , left).
To move the units over the zero plane, the mouse is moved in the XGUI
display to the position x=3, y=0 and the keys "` U 3 M"' are
pressed. The result is displayed in figure (right).
Figure: Wire-frame model in parallel projection (left) and solid model
in central projection (right)
The output layer, which is assigned the z-value 6, is treated
accordingly. Now the network may be rotated to any position
(figure , left).
Finally the central projection and the illumination may be turned
on (figure , right).
These are the links in the wire-frame model
(figure , left).The network with links in the
solid model looks like figure (right).

model (right)
