This is also called a Three-dimensional drawing because in an Isometric Drawing there are three mutually perpendicular axes ( plural form of 'axis' ) that meet at a common point and also make an angle of 120° with each other. In the following picture provided, assume three axes named X, Y, and Z make a 120° angle with each other and meet at a point 'O'. Isometric Drawing Actually, Isometric Drawing is a type of Pictorial Drawing. A pictorial drawing can be classified into three groups..... 1) Isometric Drawing 2) Oblique Drawing 3) Perspective Drawing.
