Mechanical Drawing
Architecture has been called "The Father of all the Arts", because it combines two and three-dimensional art, art history, design, graphics and sculpture. Architects also must consider the social aspects of design, and the effect that their buildings will have on the environment.
Technical drawing, also known as drafting or mechanical drawing, is the practice of creating accurate representations of objects for technical, architectural and engineering needs. A practitioner of the craft is known as a draftsman, draftsperson (or draughtsman, draughtsperson in the UK), and recently, "drafter". Today the mechanics of the drafting task have been greatly accelerated, through the use of CADD systems, but regardless of whether a draft is drawn by hand or with computer assistance, the drawing must be reproducible.

Types of Mechanical Drawing:
Orthographic Projection:
1
:

drawing surface in which the lines of projection are perpendicular to
the drawing surface
2
:
the representation of related views of an object as if they were all in
the same plane and projected by orthographic projection
First Known Use of ORTHOGRAPHIC PROJECTION
1668
