Production drawings are complete sets of drawings that detail the manufacturing and assembly of products.
Machine operators, production line workers and supervisors all use production drawings.
Design engineers also use orthographic or pictorial views called "working cases" to record their ideas. These preliminary sketches are used as the basis for both the component and assembly drawings. Production drawings are 'drawn' information prepared by the design team for use by the construction or production team, the main purpose of which is to define the size, shape, location and production of the building or component'.
Orthographic projections are often supplied, giving views of machine parts and their assembly in an accessible form akin to artistic rendering in perspective, sometimes in exploded form which illustrates how the whole may be constructed from sub-assemblies and sub-assemblies into individual components. The production drawings may describe the preferred order in which to assemble components and if the engineering drawings call for a screw fastener to be tightened to a specific torque the production drawings would typically describe the tool to be used and how it should be calibrated.
