When you are working on complex parts that are made up of densely packed entities, this filter allows you to focus on the specific entities you want to select. You can think of filtering as a transparent overlay that filters out the entities you do not want. This makes the entities you do want easier to access. This transparent filter does not, in any way, alter your drawing. It simply acts temporarily to give you more control over your selection of geometry.

 

The Set Filter function can be accessed from the Home>Editing ribbon area . See Set Filter for more information.
