AutoCAD is a general-purpose computer aided
drafting / design application program.
It was initially developed in the early 1980's by
Autodesk Inc., California.
AutoCAD is an interactive drawing system
designed to permit a user to construct or edit a
drawing on a graphics display screen.
It is, by many estimations, the largest program in
terms of computer code ever written for a
personal computer.
This has had the effect that the features of AutoCAD that support two-dimensional drawing are
fully self-contained and can still be used as a 2D system without being concerned with its 3D
features.
From release 11 onwards, AutoCAD has provided an extension package called AME (Advanced
Modelling Extension) which provides 3D solid modelling capabilities - these allow you to form
complex solid objects by adding, subtracting and intersecting a set of simple solid primitives
(such as, boxes, cone, cylinders, spheres, etc).
In this course we will focus on the 2D drafting aspects of AutoCAD since that better reflects the
way in which this system is generally used in practice at the present time.
