This feature mirrors all compounds on the canvas or selected fragments in 3D to a selected inversion center. The chirality is changed, all R is inversed to S, and vica versa.

• The inversion center is the geometric center of the selected atoms: if there are more than one selected fragment, then all fragments are inversed separately to their geometric center.

• The inversion center is a selected atom: all fragments are mirrored to the selected atom.
