Definition of projection in engineering drawing:
As the object that are designed or drawn have 3 sides in terms of length, breadth and height, and the object that is the sheet we drawn in has 2 sides meaning 2D.
To draw a 3D image on the 2D plane we use various contour points on the objects, plot various plane points, visual rays, straight lines, therefore, image obtained by such plot points on various points on a single 2D plane is known as Projection.
