Introduction to AUTOCAD:
AutoCAD,
created by Autodesk, is the most widely used technical drawing program
wherewith over 1.25 million registered users. Autodesk is the fourth
largest PC software company in the world. According to the Autodesk, and
for Computer Aided Design (CAD), but can also stand for Computer Aided
Drafting or Drawing.
The first version of AutoCAD
came out in 1982 running under DOS. AutoCAD was the first significant
CAD Program to run on a desktop computer. At the time most other
technical drawing programs ran on high end workstations or even
mainframes. AutoCAD success has been attributed to its famous open
architecture. The support of Auto LISP a programming language designed
especially for AutoCAD has also been a major factor in making AutoCAD
the standard for serious technical drawing.
Although AutoCAD is primarily thought of as a CAD
application used for 2D designs, it has a powerful 3D modelling engine
that allows you to create 3D models of buildings or small parts used in a
machine. 3D modelling in AutoCAD was introduced over a decade ago with
AutoCAD R13 (and even before that as an add-on called Autodesk Modelling
Extension for AutoCAD R12), but creating 3D models was very time
consuming. In recent releases of AutoCAD, the 3D modelling features have
been completely overhauled to allow conceptual designing in AutoCAD and
to create high-quality presentation renderings with less effort.
AutoCAD
not only gives you the 2D drafting tools that you’ve come to use
everyday, but it also provides a robust set of tools for 3D modelling
and visualizing the 3D models you can create.
Autodesk
has created a program with unequalled features and capabilities,
including 3D modelling and visualization access to external databases,
intelligent dimensioning, importing and exporting of the file formats
and many more.
Autodesk has developed a virtual
corporation which includes programmers who create software designed to
work with AutoCAD, dealers who provide technical support training and
courses to over one million users each year.
Autodesk
has expanded AutoCAD into a whole product line of programs with AutoCAD
as a base and specialized, discipline-specific add-on built on top and
included as one complete product.
The major disciplines that use AutoCAD are:
- Architectural
- Mechanical
- GIS (Geographical Information Systems)
- Facilities Management
- Electrical / Electronic
- Multimedia
These discipline specific flavour’s of AutoCAD include:
- Autodesk Architectural Desktop and Autodesk Building Systems (mechanical, electrical, and plumbing),
- Autodesk Mechanical Desktop,
- Autodesk Map,
- AutoCAD Land Desktop,
- Autodesk Survey, and
- Autodesk Civil Design.
Autodesk
now offers Autodesk Revit and Autodesk Inventor, software applications
that compete with Architectural Desktop and Mechanical Desktop,
respectively. Revit and Inventor are not based on AutoCAD; they
sacrifice AutoCAD compatibility in favour of a more fundamentally
design- and 3D-oriented approach to CAD. Whether they ultimately will
replace the traditional AutoCAD-based applications remains to be seen.
Thus far, most companies seem to be sticking with AutoCAD and the
AutoCAD-based Desktop applications.
However there
are many other lesser known uses for AutoCAD, such as Pattern Making in
the Garment Industry, Sign Making and so on.
