Orthographic projection is a method used in technical drawing to represent three-dimensional objects in two dimensions. It involves projecting the object's features onto a flat surface from different angles, typically the front, top, and side views. This technique helps convey accurate dimensions and shapes without distortion. In orthographic projection, each view is drawn to scale and aligned with the others, allowing for easy interpretation. This approach is commonly used in fields like engineering, architecture, and design, where precise measurements are crucial. It provides a clear and comprehensive understanding of the object's structure and layout.
