Drawing Types and Scales

Engineering drawings are typically generated using computer-aided design (CAD) systems.
Scale on drawings indicates the ratio between the drawing size and the actual size of the object.
A scale of 1:10 means that an object 100mm long in real life would measure 10mm on the drawing.
General Arrangement (GA) drawings provide an overview of entire devices or structures at a small scale (e.g., 1:100 for a building).
Detail drawings focus on specific components with larger scales, often at actual size (1:1) or even larger (e.g., 2:1), for detailed representation.
Schematic drawings are used for electrical circuits and pipe/ductwork, providing simplified representations of these systems.

Types of Views Used on Drawings

Plan view shows an object from above, displaying its arrangement.
Section view provides a cut-through perspective revealing the internal structure of a component.
Elevations present multiple views of an object from different sides, showcasing its overall form.
Exploded view displays an assembly with components spaced out, demonstrating the relationships between parts for assembly and maintenance.

2D vs. 3D Views

Two-dimensional (2D) views, including plans, sections, and elevations, can make it difficult to understand complex assemblies.
Three-dimensional (3D) views, employing oblique or isometric projections, offer a more comprehensive understanding of complex assemblies.

Test your knowledge on different types of engineering drawings and scales used in design. This quiz covers concepts such as General Arrangement, Detail, and Schematic drawings, as well as various views like Plan and Section. Enhance your understanding of how these elements play a crucial role in engineering design.
