Drawing Sketching on isometric paper: Two views (plan and elevation) of a object are shown in Fig 16A.
By using a isometric paper which gives perfect visual effect of the object. Isometric grid paper placed in work book.
By counting off the isometric grid spaces equal to the squares on the corresponding given views sketch in the
enclosing box and also the surface A. (Fig 16B)
Sketch the other surfaces B,C,E etc to complete the isometric views. (Fig 16C & 16D)
