Blueprints Have Three Main Parts: Drawing - Graphical representation that shows the exactshape of a component. Dimensions - Numbers that provide the measurementsof a piece of a drawing. Notes - Include information that cannot be easilyidentified on the drawing or other information needed tofabricate the component. Some information may beimportant and some may be irrelevant.Sealed Source & Device WorkshopBlueprint Reading: 3
Drawings:Exploded View: good for viewing how pieces fit together usually no dimensions or piece informationSealed Source & Device WorkshopBlueprint Reading: 4
Drawings:Isometric:Sealed Source & Device WorkshopOrthographic:Blueprint Reading: 5
Orthographic:Each component has 6 sides and each can be shown as a viewon a drawing. Typically, only 3 views (front, top, and right side)are provided unless other views are needed for clarification.Sealed Source & Device WorkshopBlueprint Reading: 6
