Molecule Strain and 3D View

When this feature is selected, several calculations are run on the desired molecule to determine bond lengths, angles, and strain within the molecule. If molecular strain is detected, affected centers will be highlighted in red. 

The 3D model can be rotated by clicking on the structure and holding, while moving your mouse in the desired direction. You can save the 3D structure by right clicking on it, and selecting ‘Save image as’ or ‘Copy image’.
