void sclfix (isfixed) D3PLT.C Level 1
 
int isfixed = 1 The 3-D axes scaling will not be changed from plot to plot, allowing pictures to get smaller as the viewing distance is increased. 
= 0 Each plot will be scaled individually to make the workbox fill the available space (default).
 
sclfix() allows the user to draw several 3-D surfaces using the same scaling.
