Understanding Orthographic Projection in Technical Drawings and Blueprints

Orthographic projection is a type of graphical projection that displays an object or scene from the point of view of a camera that is perpendicular to the object or scene. This means that the camera is positioned so that its optical axis is parallel to the plane of the object or scene, and the image produced by the camera shows the object or scene as it would appear if you were looking directly at it from the side.

In other words, orthographic projection is a way of drawing or displaying an object or scene in two dimensions, as if you were looking at it straight on, rather than from an angle. This type of projection is often used in technical drawings and blueprints, where it is important to show the object or scene in a clear and accurate manner, without any distortion or perspective.

Orthographic projection can be further divided into three types:

1. Front orthographic projection: This type of projection shows the object or scene as it would appear if you were facing it directly, with the camera positioned directly in front of the object or scene.
2. Side orthographic projection: This type of projection shows the object or scene as it would appear if you were standing to one side of it, with the camera positioned at a 90-degree angle to the object or scene.
3. Top orthographic projection: This type of projection shows the object or scene as it would appear if you were looking down on it from directly above, with the camera positioned directly overhead.
