Bond Centric Manipulate Tool
From Avogadro
The bond-centric manipulation tool provides a "chemically-oriented" way to change bond lengths, angles, and dihedral angles.
- Click on a bond.
- Right click and drag to change the bond length. The current bond length is listed in the bottom left corner.
- Left click and drag to change the bond angle as indicated. The appropriate angles will update interactively.
- Click on an atom neighboring the bond and drag to change the dihedral angle. The dihedral measurements update interactively.
The plane used for angle manipulation can be changed. Click on the plane and drag to change the orientation.
- The "Snap-to Bonds" (and Snap-to Threshold) will set whether the angle plane will "snap" when close to a neighboring bond.
