Hello guys, i was wondring if anyone knows a 3d moelcular modeling software(molecular set subsitute) that i can download?

jmol is good. What do you want to use it for?

hello mike, i want to use it to practice rotation molecules just to get an idea of how it will look and to be able to imagine it in my head for my exam. for example:achiral/chiral molecules, enantomers.

What about Chem3D ultra?

ChemSketch
http://www.acdlabs.com/download/
Has a free version and you can download a free 3D viewer add on to view models in 3D.

I would just download jmol and then search the internet for the molecules you want to look at (you may not even want to download jmol and just look at the molecules on peoples websites). You can search for .pdb files of molecules.

Although ChemSketch is good for naming molecules, I prefer ISIS Draw because there are many templates and drawing geometrically sound structures is far easier.

I like Pymol (http://pymol.sourceforge.net/ for 3D visualisation) but I can't compare it to anything else because I haven't tried anything else. I drew a solid phase peptide picture in pymol which I think is kind of cool: http://en.wikipedia.org/wiki/Image:SPPS.jpg

If you like solid crystals then you can take PowderCell (http://users.omskreg.ru/~kolosov/bam/a_v/v_1/powder/e_cell.htm) I think it's not a common program but it is pretty cool.

if you like orbitals go to www.orbitals.com (http://www.orbitals.com)

A good forcefield program: Try Tinker

Arguslab is also a relatively good program (freeware). But that especially accurate.
