The Advent of the PC and CAD Design

One of the ways in which the advent of the PC has had a great effect over the way we live is CAD design. Computer assisted drawing, or CAD for short, has only been available for about a decade, but it has quite simply revolutionized every single aspect of the design world. Like most other computer assisted technologies, CAD design has developed drastically since it first appeared.

In the beginning CAD design programs created two-dimensional drawings that still were infinitely more complicated than the human brain could easily conceive. This is because they are the product of the input of many human brains over a period of time. It's an easy way of simplifying the design work, and making sure that every drawing is the result of combined thinking on a huge scale, which would be very difficult and costly to arrange in the real world.

Benefits Accrued Between Design Fields

Some of the applications for CAD design include mechanical engineering of all kinds, civil engineering, architecture, plastic molding, all branches of science projects and much more. This means that not only do designers benefit from each other's work, but the different design fields can also benefit from advances in other fields. For example in the area of stress testing which is important to the design and production of automobiles, aircraft and machinery as well as buildings.

Although to begin with CAD design drawings were only two dimensional, gradually the software was added to and developed until designers can now make use of a fully three-dimensional perspective to all their drawings. This has extensive application in all fields of design. It means that virtual and then a practical model of any design can be developed.

CAD Design and CAM Integration

This is known as the integration between CAD design and CAM, which is computer assisted manufacturing. The two technologies, when integrated are a way of eliminating many of the stages of design and manufacture that used to make the production of new designs so lengthy in the past. It means that designs for buildings, machines and cars or aircraft can be rendered far less a matter of hit and miss, and more a process where every design and manufacture project is able to make full use of experiences from previous projects as they are progressively included in the CAD design software.

In the days before CAD design, if a design prototype didn't work as expected, it would sometimes take years of hit-and-miss efforts at the same project until the problems were ironed out. Now, with collective and progressive experience being added to the CAD design resource, great strides have and can still be made in the fields of aerodynamics, stress testing, stress and failure analysis and so on.

Speeding Up the Design Process

Basically, design and prototype testing can move infinitely faster than they did in the days before PCs. This means that, in theory at least, design and development should be much cheaper than it was in the past. It also allows for a much greater volume and variety in design and production.

The beauty of CAD design is that it can and is being constantly updated and improved to keep step with developments in each field. There are many different kinds of CAD design software. Each more suited to a particular field of design. In addition most CAD design programs are designed to work with other programs, for example CAM programs. Before buying programs from either category, it's good idea to make sure they work together with no integration problems.
