Hide Selected

(default keyboard shortcut - ) 

View > View > Hide Selected will hide selected polygons that you don’t want edited. This makes it easier to work on parts of a complex object without splitting it up between layers.

The polygons are still there, but any editing operations will not directly affect the hidden polygons unless they share points that are edited.

Hide Unselected

(default keyboard shortcut =) 

View > View > Hide Unselected will hide all unselected polygons. Select all of the polygons that you don’t want to hide and then Hide Unselected to hide all the unselected polygons and keep the selected ones visible.

Although you cannot directly affect hidden polygons, you can affect them if you modify visible polygons that share points.

Hide Invert

(default keyboard shortcut |) 

View > View > Hide Invert will swap the polygons presently visible with polygons that have had Hide Selected applied to them.

Although you cannot directly affect hidden polygons, you can affect them if you modify visible polygons that share points.

Unhide

(default keyboard shortcut \)

Selecting Unhide All (View > View > Unhide) will reveal all hidden geometry.
