CRYSTAL AND MOLEC DRAWING PROG NEEDED.

[SKENNEDY $#at#$ ccit.arizona.edu]

 	I am desperate in need of a program which is capable of
 drawing  crystals in a three dimensional format, either line
 or  solid (color solid preferred), on an Ms-Dos platform.  I
 have  seen a Mac  program, called Shape,  which will do this
 given  the crystal class, the  unit cell parameters, and the
 indices and central distance for one face of each form; but,
 have  been  unsuccessful in  finding a  Dos version in time.
 Other desirable  features would be options  that allow the
 crystal to be twinned or in grown with another crystal.
 	On the atomic side of things,  a program which can draw
 the atomic structure given a formula and/or other properties
 would be spectacular.
