MOLDRAW shows a toolbar with the most common options available as a single mouse click. The toolbar is shown below:

 

 

 

  • Read: reads a prexistent .MOL file
  • Write: writes a .MOL file of the present structure. Connectivity and other information are also stored in the .MOL file. Unit cell infos are lost
  • Import: opens the dialog to import a variety of molecular format 
  • Export: opens a form to export the coordinates in different formats
  • Imp GAU98: imports a structure from the .LOG/.OUT Gaussian98/G03 (http://www.gaussian.com ) output file.
  • Imp CRY03: imports a structure from the .OUT CRYSTAL03/06 (http://www.crystal.unito.it) output file.
  • Cell: generates the crystal unit cell content of the actual structure.
  • Pack: generates a cell packing in a user contrallable fashion.
  • Dist: calculates the distance (Angstrom) between any two atoms.
  • Angle: calculates the bond angle (degrees) between any three different atoms.
  • Tors: calculates the torsion angle (degrees) defined by four non-collinear atoms.
  • HB-/+: shows/hides the H-bonds in the actual structure.
  • Label atom: labels the atom selected by the left-button mouse click.
  • Unlabel all: unalbels all previously labelled atoms.
  • Stick: renders the structure in sticks.
  • Stick+B: renders the structure in stick+balls.
  • Wire: renders the structure in sticks whose thickness dependent on the position.
  • Tube: renders the structure in sticks of bigger thickness.
  • Spokes: renders the structure in ball & spokes (uncolored).
  • Solid: renders the structure in ball & spokes (colored).
  • CPK-: renders the structure in quick CPK scaled van der Waals spheres.
  • CPK+: renders the structure in slow CPK scaled van der Waals spheres.
  • Sel all atom: selects all atoms belonging to the actual structure.
  • Sel atom: selects atoms clicked with the left-button mouse.
  • Recenter: re-centers the actual structure on the screen.
  • Sel fragment: selects one or more unconnected fragments within the structure.
  • Ren atom: renames an atom clicked by left-button mouse with one selected from a list.
  • Del atom: removes atoms clicked by the left-button mouse.
  • Link: connects clicked atoms with a bond.
  • Unlink: disconnects clicked atoms.
