Limits of three-dimensional parameters
The following table shows the limits of three-dimensional transformation 
parameters.
The three-dimensional parameters of an image change when you use the 
trackball or Z-ring to execute a transformation. You can also execute a 
transformation by entering parameter values from the numeric keypad control 
block.
