# Database of 3D crystal models [closed]

I'm looking for a database of very basic crystal models for all the various types - triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal, and cubic.

A basic example would be a CAD file for a cube, to represent the cubic structure. I don't want like a packing model which shows the individual atoms because I'm trying to represent macroscopic crystals.

Any ideas where I could find what I'm looking for? Not a 3D graphic designer.

• Crystallographic database. CAD file formats are not used in crystallography (maybe unless you are an architect building another Atomium), look for CIF instead. – andselisk Jul 29 '20 at 6:27
• There are exactly seven of them, all of which you already listed in your question. Why a database? And what do you want to do with them, with what software? – Karl Jul 29 '20 at 6:49
• sounds like you need a database of polyhedra, not chemicals – gilleain Jul 29 '20 at 8:19
• for example, something like : georgehart.com/virtual-polyhedra/vp.html – gilleain Jul 29 '20 at 8:38

Joining @Karl's comment on «what do you want to do with them?» the work to present point groups is work already solved. For off-line teaching, the freely accessible collection of the 32 point groups by Casas and Estop by (UB Barcelona) may suit your needs:
The model data are provided as interactive 3D .pdf files which a reader like Adobe Acrobat 9.0 may let you toggle on/off the axes / planes, etc.
