Try the csed component of CACTVS. See
It lets you design molecules from scratch, and with the interface
to CORINA you can get a 3D structure for a small molecule. It also
has a 3D viewer or you can use one of many other existing structure
This works on mnay unix machines. If you are on a PC; I think a
basic commercial product for this is about $100 or so.
