First vs Third Angle – Orthographic Views

Orthographic views allow us to represent a 3D object in 2D on a drawing. Orthographic views can show us an object viewed from each direction. How the views are laid out on a drawing depends on whether 3rd angle or 1st angle projection is being used. You can tell which angle projection is used by the symbol
