Encyclopedia Article for isometric drawing

method of graphic representation of three-dimensional objects, used by engineers, technical illustrators, and, occasionally, architects. The technique is intended to combine the illusion of depth, as in a perspective rendering, with the undistorted presentation of the object's principal dimensions, that is, those parallel to a chosen set of three mutually perpendicular coordinate axes.
