What Is CAD

Computer Aided Design (CAD) is a form of design in which people work with computers to create ideas, models, and prototypes. CAD was originally developed to assist people with technical drawing and drafting, but it has expanded to include numerous other potential uses. A variety of software products designed for CAD can be found on the market, with many being targeted to a specific application or industry.

Draw Technical Drawing And Drafting

Drafting and technical drawing can be very painstaking, and they require some special skills. Using CAD for drafting still requires many of the same skills, but by working with a computer instead of on paper, people can be much more efficient. They can also play around with ideas much more easily, moving design elements around and running the design through software programs which can determine whether or not the design is structurally viable. For example, an architect working on a bridge can test the design in simulations to see if it will withstand the load it will need to carry.

CAD can be used to design structures, mechanical components, and molecules, among other things. One advantage of using CAD is that people don’t have to make prototypes to demonstrate a project and its potential, as they can use a three dimensional modeling program to show people how something might look. CAD also allows for endless variations and experiments to show how the look and feel of something can be altered, and these can be done at the click of a button, rather than with painstaking drafting work.

Casual users sometimes like to play with CAD for things like deciding how to organize their furniture, or lay out a garden. They can drag and drop elements and play with the space in a variety of ways, and generate a configuration which will be suitable and aesthetically pleasing. CAD is used by professionals in a number of industries across the manufacturing sector, and it can also appear in some surprising places, like forensics labs, where researchers recreate crime scenes on a computer to explore scenarios.

Advanced CAD programs usually require extensive training from their users, as they can be very complex and challenging to work with. More casual programs can be learned in shorter periods of time, with some designed to allow people to work within the program immediately, learning as they go. Simple programs can also sometimes have their functionality increased with expansion packs which are designed to provide additional features, so that people can work within a program they are familiar with when they want to develop more complex designs.

What is AutoCAD

AutoCAD was one of the first Computer Aided Design programs to be made available on personal computers. It is built to help people design buildings, products, or public spaces, without having to draw up plans by hand. It was released in 1982 by Autodesk, Inc., and offered a personal solution to software that was before then released only for larger workstations. While CAD programs prior to AutoCAD required massive amounts of computing power in the form of gigantic computers, AutoCAD streamlined its operating and optimized it for the IBM PC, allowing people to work from home or on their own work computers.

First Computer Aided Design (CAD) Programs

Through the 1980s, AutoCAD functioned mostly by using simple lines and circles, and text overlays, to set up custom objects. Beginning in the 1990s, AutoCAD began utilizing more robust custom object features, built with an Advanced Programming Interface using C++. And starting in 2007 AutoCAD has had much more advanced 3D tools that allow for greater 3D modeling and exploration of models, with high-quality, fast-moving rendering.

The modern version of AutoCAD allows for much more than simply C++ programming. It has set the standard for operability in terms of Advanced Programming Interfaces in CAD, and can use VBA, .NET, AutoLISP, and Visual LISP, as well as the C++ based ObjectARX. This robust programming set has allowed for great extensibility for AutoCAD, and there are a number of more specific AutoCAD programs, including AutoCAD Electrical, AutoCAD Civil 3D, and AutoCAD Architecture.

The file format that AutoCAD uses, the DWG format, has become a standard for all CAD work. Autodesk shifts its estimates of how many DWG files are in operation in the world, but generally places the number at quite a bit more than one billion. Although a number of other CAD programs exist at this point, including programs for Mac OSX and NIX systems, AutoCAD remains the industry leader and sets a number of standards in the CAD community.

AutoCAD An Autodesk –Software

In addition to AutoCAD, Autodesk produces many other design programs, all built to help designers or architects work on specific projects. Their software is focused on all aspects of rendering, both in 2D and 3D, and they consistently seek to push the envelope on what their technologies can achieve. Autodesk software includes industry standards for animation and product design, in addition to AutoCAD itself. For example, files created with their design software may be exported and sent to prototyping facilities, which can input them into 3D printers to generate immediate 3D prototypes for an affordable fee. This seamless interaction between home software and affordable high-speed prototyping is in many ways changing the way design is being undertaken, and has largely removed barriers to entry.
