Orthographic Projections

Orthographic projection is a method of representing three-dimensional objects in two dimensions. It is a type of parallel projection where the projection lines are perpendicular to the projection plane. This technique is widely used in engineering drawings and technical illustrations to accurately convey the shape, size, and details of an object. 

Projection Planes: Orthographic projections typically involve projecting the object onto three principal planes:

• Front View (Elevation): Shows the height and width of the object.

• Top View (Plan): Displays the width and depth of the object.

• Side View (Profile): Represents the height and depth of the object.

Views: The most common views used in orthographic projections are:

• Front View

• Top View

• Right Side View

• Left Side View

• Bottom View

• Rear View

Applications:

• Engineering and Architectural Drawings:

Orthographic projections are the standard method for creating detailed and accurate technical drawings of mechanical parts, buildings, and other structures.

• Manufacturing:

Used to create detailed blueprints that guide the manufacturing process, ensuring that parts are produced to the correct dimensions and specifications.

• Computer-Aided Design (CAD):

Orthographic projections are fundamental in CAD software for creating and visualizing 3D models and producing 2D drawings from them.

• Technical Illustrations:

Used in manuals and instructional materials to clearly communicate how to assemble or operate products, machinery, or equipment.
