Lock Cartesian Properties of an Atom

How we can lock cartesians properties of an atom then doing geometry optimizations with Avogadro?
It’s likely I have much molecule that simulated, then I just want to lock one of x-axis of an atom.

It’s likely I have much molecule that simulated, then I just want to lock one of x-axis of an atom.

Use the “Select” tool to select an atom or atoms. Go to Extensions -> Molecular Mechanics -> Fix Selected atoms.

If you just want to lock the x-axis, then choose “Constraints…” instead of “Fix Selected” and freeze the x-coordinate. (It’s possible.)

Hope that helps,

ah, thanks. that’s help me a lot… :slight_smile:
