SHAPE is a program for drawing the external morphology (faces) of crystals and quasi-crystals, and also for drawing sections of crystals. It will draw any single crystal and most twins and epitaxial intergrowths. You enter the crystal axis lengths and angles, the symbol for the crystal class, and one face of each form (symmetry equivalent set).
