The Diameters tab in the Drill Group dialog box enables you to include all holes of a specified diameter.

When you click Add, the Select hole diameter dialog box opens. It lists all the hole diameters present in the model. Select a diameter from the list, or click Select and select a cylindrical surface on the model to specify the diameter. The system adds all holes of the specified diameter to the Hole Group.

The diameter values selected so far are listed in the central list box on the Diameters tab. To remove all holes of a specified diameter, select its value in the list box and click Delete. To remove some of the holes of a specified diameter, use the Axes tab.
