Standard views in European drawings
Front, side and top
These standard views help to provide a comprehensive representation of an object in engineering drawings.
Standard views in American drawings
Top, left side and rear
American drawings may have a different standard view arrangement compared to European drawings.
Shows the object as if part of it is removed so that the interior shape is seen clearly
Sectional view
Sectional views are used in technical drawings to reveal the internal structure of an object.
Drawings used in the design, construction & maintenance of engineering projects
Production drawing
Production drawings are essential for communicating design specifications in engineering projects.
Drawings used in the design, construction and maintenance of jigs, tools & checking fixtures
Tool drawings
Tool drawings are specific technical drawings that focus on the design and specifications of tools and fixtures.
Used in the detailing or fabrication of single parts
Detail drawing
Detail drawings provide detailed information about individual parts for manufacturing or assembly purposes.
Function is to show the relationship of 2 or more parts and subordinate assemblies
Assembly drawing
Assembly drawings illustrate how multiple parts come together to form a complete product or structure.
Designed to describe exactly where on the airplane/vehicle, certain parts or assemblies are to be permanently affixed
Installation drawings
Installation drawings provide precise instructions for the placement and attachment of components in a specific location.
Parts are expanded outward so that each part can be identified by its physical appearance or name
Exploded view drawing
Exploded view drawings visually separate components to show how they fit together in an assembly.
Used to show every part in the assembly
Exploded view drawing
Exploded view drawings are often used to provide a comprehensive breakdown of all components in an assembly.
