Moving/rotating 2 or more molecules independently

General Discussion

Hello!
I am trying to use Avogadro for teaching purposes. I would like to know if it were possible to build 2 molecules and “freeze” the first move at will the second.
Thanks for the help and Merry Christmas to all
Francesco

Yes, in Avogadro 1.x, you can select a set of atoms and “freeze” them:

  1. Select the atoms or molecule you wish to fix in place.
  2. Go to Extensions -> Molecular Mechanics -> Fix Selected Atoms

I’ll mention that yes, this feature will make Avogadro 2. Hopefully I’ll get some free time in the next few weeks to finish the new optimization framework.

Hi Ghutchis,
the fixed atom mode does not work. It moves the whole system even in the fixed mode, Any other way to fix a part of a system and move the other parts toward the fixed atoms?

This is probably better suited for a new thread. Can you be a bit more specific about what you’re seeing / asking and what version you’re using, OS, etc.?
