Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be rep-
resented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 5456-3 was prepared by Technical Committee
ISOnC 10, Technical drawings, product definition and related documen-
tation, Subcommittee SC 1, Basic conventions.
IS0 5456 consists of the following parts, under the general title Technical
drawings - Projection methods:
- Part 1: Synopsis
Part 2: Orthographic representations
Part 3: Axonome tric representations
Part 4: Central projection

Introduction
Axonometric representations are simple pictorial representations obtained
by projecting the object to be represented from an infinitely distant point
(projection centre) on a single projection plane (normally the drawing sur-
face). This kind of parallel projection gives an adequate approximation for
distant views.
The resulting representation depends on the shape of the object and on
the relative positions of the projection centre, the projection plane and the
object itself.
Among the infinite possibilities of axonometric representation, only a few
types are recommended for technical drawings in all fields of technical
activities (mechanical, electrical, construction, etc.).
Axonometric representations are not as commonly used in technical
drawings as are orthographic representations.
