Excerpt from Descriptive Geometry for Students in Engineering Science and Architecture: A Carefully Graded Course of Instruction

Section 1. In Descriptive Geometry the object is chiefly to prepare drawings as follows: -

() Those which will display or describe by different views any object or arrangement oi lines or figures discussed;

(b) Those which will, by various analytical and constructive methods and
operations, discover or disclose facts as to shapes, inclinations, appearances, sizes, etc.; and

(c) Those which will represent planes and how they may be disposed to one another.

The views mentioned above in (a) are projections, and are made on what arc called planes of projection. The same projection planes, two in number, are also made use of in the discussion of planes referred to in (c), lines being drawn over the planes of projection and made to represent other planes in various attitudes with respect to the projection planes.

The planes of projection are the Horizontal Plane and the Vertical Plane. These arc considered as being fixed, and the lines, planes, figures or objects are considered as having a relation to them - near or otherwise as to distance, inclined or otherwise as to altitude.

The drawings made either represent points, lines, figures or objects by views thrown perpendicularly on to these planes of projection (the H.P. and the V.P. as they are commonly called), or they indicate the intersection of the planes of projection by lines and planes.
