Drafting, also called mechanical drawing, is a drawing done with the aid of such instruments as T-squares, triangles, compasses, and scales, specifically for the systematic representation and dimensional specification of architectural and engineering structures.
Freehand drawing is the art, process, or technique of drawing by hand without the aid of drafting tools or mechanical devices, in order to represent or visualize an idea.
