Mechnical Drafting

A brief summary

Engineering language is expressed in drawing & drafting .Its a means of communicating with dimensions ,proportions , scale of machine or a building describing its details like the shape , size and section by a verbal or written language is very difficult henceforth Graphic language is used to express drawings .People who do these measured drawings are called as Draftsmen. Mechanical draftsman play a key role in the civil design industry .They do the 2d & 3d modeling of the buildings. They get well paid as a fresher and with experience. .
