Subject:	Summary: looking for molecular modeling program on web or free-long!

Sometime ago I asked the following question and got many helpful
answers.  I ended up using isis/draw and weblab viewer both free to
download.  This is long

Net 4.5 will allow you to sketch molecules in 2D using ChemDraw Net and build 3D
models (with a six heavy atom) limit using Chem3D Net.  Chem3D Net will also
allow visualization (including surface visualization) of molecules stored in
various formats.

and 2D to 3D conversion and MM2 calculations.
