The following message was posted to the newsgroup: SCI.CHEM

I just thought that you may be interested in this (or something
like this) for visualization of 3D crystal geometries.

>Oslo, February, 1997. Crystal Structure Design AS is proud to announce
>that CrystalDesigner 6.0b2 for Macintosh is now available for downloading
>from <http://www.crystaldesigner.no> or from
><ftp://ftp.crystaldesigner.no/>. 
>
>CrystalDesigner is a tool for building, studying and visualising all kinds
>of crystal structure on the Macintosh platform. CrystalDesigner is an
>ideal tool for both teaching and scientific studies. The software is
>intended to be used by students and teachers at colleges and universities,
>as well as in industrial research.
>
>You can enter crystal structure data inside the program or import them
>from CIF files. Entering data inside a crystallography program has never
>been easier.  All 230 space groups from the "International Tables for
>Crystallography" and more than 700 different atomic, covalent and ionic
>radii are built into the program.
>
>The crystal structure can be viewed in four different ways; as unit cells
>or multiples of it; as a plane with a user defined thickness; by
>coordination around a selected atom within a user defined ratio; or as a
>molecule defined by the atom positions. All are done in separate graph
>windows.
>
>The atoms in the drawing may alternatively be viewed as points, circles or
>spheres. Bonds between atoms can be created and viewed as lines, cones or
>cylinders. Groups of atoms can alternatively be viewed as polyhedra. 
>
>The program requires System 7 or higher, 2.5 MB available memory, 4 MB
>free hard disk space, and a Macintosh with a 68020 CPU or higher.
>Accelerated for Power Macintosh.
>
>In order to take advantage of the possibility to export crystal structure
>data and graphics, it is necessary to have a commercial software license. 
>Please note that you can import CIF files and save your own entered
>imported data with the free version.

>What's new in CrystalDesigner 6.0
>-----------------------------------
>
>CrystalDesigner 6.0 has now full support for coordination polyhedra.  In
>addition, it is now also possible to insert a single polyhedron around a
>single user selected atom. You may also draw atoms, bonds and polyhedra
>simultaneously.
>
>New main features:
>
>- Space group support for all the different cell choices in 
>  the monoclinic crystal system
>-  Space group support for both first and second choice of origin 
>   in the orthorhombic, tetragonal and cubic crystal systems.
>
>-  Full support for coordination polyhedra up to 18
>-  Possibility to insert a polyhedron around a user selected atom
>-  Possibility to display atoms, bonds and polyhedra simultaneously
>-  Bonds can be coloured by using the atoms colour or a defined colour
>-  Bonds between atoms and corner of polyhedra may be drawn either 
>   as lines or cones 
>
>-  A new crystal structure note window has been added
>-  Simpler user interface
>-  A handful bug fixes
>
