To Exclude Surfaces and Outer Loops
The Exclude option is available only if you gather using an option other than Surf & Bnd (for example, Surfaces). It allows you to:
Surfaces—Exclude some of the chosen surfaces by selecting each of them individually. This is especially convenient when gathering using Features or Mill Surf.
Loops—Exclude outer loops. Use this option to delete unwanted portions of surfaces selected for gathering.
