Albert,

It sounds like you need to work through our membrane tutorial for VMD/NAMD:

http://www.ks.uiuc.edu/Training/Tutorials/science/membrane/mem-tutorial.pdf

Associated files needed to perform tutorial exercises:
https://netfiles.uiuc.edu/TCBG_Files/shared/membrane-tutorial-files.tar.gz

Also, you manually move independent molecules, representations, etc by
selecting from the menu: Mouse>Move> .... and then Atom, Residue, Fragment,
Molecule, or Rep. Then click on the molecule and drag to move, or
shift+click and drag to rotate. In your case, Molecule and/or Rep are
likely the best choices. How to further move molecules is covered more in
the main VMD tutorial and manual.

Main VMD tutorial:

Best,
Chris
