Engineering drawings are a graphical language used to communicate technical design information between engineers. There are different projection methods for engineering drawings, including orthographic projection and axonometric projection. Orthographic projection uses parallel lines of sight to produce accurate multi-view drawings that show the true shape and size of an object through multiple two-dimensional views. Axonometric projection shows an object's three dimensions in a single view, making it easier to understand but introducing distortions from the true shape and size. Understanding engineering graphics and different projection methods is essential for effective technical communication.
