Two projection methods are commonly used to draw Multiview drawings. These methods are known as orthographic projection and isometric projection. Orthographic projection involves drawing the object from different views, such as top, front, and side, to show all the dimensions accurately. Isometric projection, on the other hand, represents the object in a three-dimensional view, where all three axes are equally foreshortened. These two methods are widely used in engineering, architecture, and design to accurately represent objects and communicate their dimensions and features.
