Orthographic Projection ■( Orthographic projection is the method of projecting views of an object on three planes that are perpendicular to each other. Imagine the object whose orthographic projections are needed to be enclosed by a box. To obtain the orthographic projections on paper,visualize unfolding the top and the right sides of the box along the lines H/F and F/P respectively. Shanghai Jiao Tong University 12

Orthographic Projection If the line of sight A is in the vertical direction and is perpendicular to the top side of the box,the projection of the object on the top side of the box,which is obtained by viewing the object along line of sight A is called the top view. If the line of sight B is in the horizontal direction and is perpendicular to the front side of the box,the corresponding projection of the object onto the front side of the object is called the front view. The projection of the object obtained on the right side of the box when the object is viewed from the right side looking along the line of sight B is called the side view(also known as the profile view).

Orthographic Projection As these sides of the box are unfolded,the top view of the object appears directly above the front view while the side or profile view appears to the right side of the front view. Shanghai Jiao Tong University 15
