Form One Superclass

This option is used to create a single class containing all of the compounds in the spreadsheet. It can also be used to create a class containing only those compounds from the classes currently selected in the Classes tab. To perform the latter operation, check the box labeled Use selected classes only ON in the Generate classes dialog (see below).

If you also check the Retain selected classes option, the original selected classes will be retained; otherwise, they will be eliminated.
