This paper describes an original Fortran program for drawing stereoscopic Views of any type of crystal structure with a graphic plotter or a 35 mm film visualization unit. Very few input cards – without format – are required since the program contains all symmetry elements for every Wyckoff position of the 230 space groups, and can perform bond length and compacity calculation, atom‐intersection testing, chemical and coordination bond drawing, as well as overlap correction for spherical atoms, so that the first treatment of any problem delivers illustrations which may be used, without retouching, for scientific publication purposes.
