After having understood the concept of missing lines, the next step in the visualization process is to
understand isometric views. For that we need to understand Pictorial drawings
Pictorial drawings are those that display a 3-D image with a 2-D view from
Projection:-A projection is the representation of an object on a plane
The projections convey all the three dimensions ( length, width & height) of the
object besides other details
Multiview drawings are used to provide accurate t
Missing Lines & Missing Views
The true and correct shape and size of an object can be rightly
understood by drawing multi-view orthographic projections.
In general practice, three views are sufficient to clear the shape of an
