Multi-view drawing

Definition 

• Multi‐view projection is a method by means of hi h th t h f bj t bwhich the exact shape of an object can be 

represented by two or more separate views produced on projection planes that are usually at right angles to each other 

• Is the method of depicting (to represent by a p g ( p ypicture) three dimension objects or concepts with sets of two dimensional drawings

Method of obtaining the view

• Either of the two methods 1 Th t l th d1. The natural method2. The “glass box” method

Natural method 

• The necessary  views are obtained by looking di tl t th ti l id f th bj tdirectly at the particular side of the object 

• i.e at the top, front and right side

“Glass Box” method

• An imaginary glass box is used to obtain the th ithree view

• The views are obtained by running projectors from points on the object to the plane

• The object is placed in a glass box.

• The side of the box represent the 6 principle planes.

• The image of the object is projected on the sides of the box.

• The box is unfolded creating the 6 principle views.
