A drawing with a partial view may be necessary to a patent application. A drawing of a large machine or device in its entirety may be divided into partial views on a single sheet, or extended over several sheets if there is no loss in facility of understanding the view. Partial views drawn on separate sheets must be capable of being linked edge to edge so that no partial view contains parts of another partial view. A smaller scale view of the whole machine should be included to show the whole formed by the partial views, and to indicate the positions of the parts shown. When a portion of a view is enlarged for magnification purposes, the view and the enlarged view must each be labeled as separate views.
