The updated version of ChemDoodle 3D v7.2 includes advanced symmetry analysis features for finite sets of atoms and small molecules. A new widget is provided to easily view the symmetry features of your scene and selections. Through the widget, analysis is provided, such as point group class, order and orbit groups. You may also use this widget to easily visualize the symmetry components as well as view animations for those components. Additionally, you may now color atoms by symmetry for another way to portray symmetry in graphics.
ChemDoodle 3D is a great tool for working with molecules in 3D
