What is computer aided drafting

Have computer aided drafting you ever wondered how architects and engineers create those intricate blueprints and technical drawings that bring buildings to life? Or perhaps you’re an aspiring designer looking to break into the world of CAD (computer aided drafting)? Either way, you’ve come to the right place! In this post, we’ll delve into the exciting realm of computer aided drafting – from its history and evolution to its practical applications in various industries. So sit back, grab a cup of coffee, and let’s get started on unlocking the mysteries behind this fascinating technology!

What is computer aided drafting?

CAD, or computer-aided design and drafting, is the use of computer technology for the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of the design, improve communications through documentation, and to create a database for manufacturing.

CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. However, it can also be in the form of physical models or prototypes that can be analyzed and tested.

The history of computer aided drafting

Today, computer-aided drafting (CAD) is an essential part of the engineering and architecture professions. But it wasn’t always this way. In the past, engineers and architects drafted by hand using pencils, rulers, and other drafting tools. This was a time-consuming and often inaccurate process.

But in the 1930s, the first CAD systems were developed. These early systems were used to design aircraft and ship hulls. They were large, expensive, and complicated to use. But they were a major improvement over manual drafting.

In the 1960s, CAD systems began to be used for architectural drawings. And in the 1970s, CAD systems became smaller and more affordable. This made them accessible to small businesses and individual professionals. Today, there are many different types of CAD software available, ranging from simple 2D drawing programs to complex 3D modeling applications.

The benefits of computer aided drafting

When it comes to creating drawings and designs, computer aided drafting (CAD) is a powerful tool that offers a number of advantages.

First, CAD software is very precise. This means that you can create detailed drawings and designs that are accurate to within a fraction of a millimeter. This is important when creating plans for buildings or other structures, as even the smallest error can have serious consequences.

Second, CAD software is very flexible. You can easily make changes to your drawings and designs, without having to start from scratch each time. This means that you can try out different ideas and quickly see how they look, without having to waste time and effort on drawing everything out by hand each time.

Third, CAD files can be shared with others easily. If you need to send your drawings or designs to someone else, you can simply email them the file or upload it to a shared server. They will then be able to open it using their own CAD software and make any changes they need to.

Finally, using CAD software can help to speed up the design process overall. Once you get used to using the software, you will be able to create drawings and designs much more quickly than if you were doing everything by hand. This can save you a lot of time in the long run, especially if you have complex projects that require multiple revisions.

The different types of computer aided drafting software

There are many different types of computer aided drafting (CAD) software available on the market today. Some of the most popular CAD software programs include Autodesk AutoCAD, PTC Creo, and Solidworks. Each of these software programs has its own unique set of features and tools that can be used to create 2D and 3D drawings.

Some of the key features that are common among all CAD software programs include the ability to create accurate drawings, the ability to edit drawings easily, and the ability to add annotations or comments to drawings. In addition, most CAD software programs also allow users to export their drawings into various file formats so that they can be viewed on different devices or printed out.

How to get started in computer aided drafting

If you’re interested in pursuing a career in computer aided drafting (CAD), there are a few things you need to do to get started. First, you’ll need to complete an accredited CAD program. While you can find many programs online, it’s important to make sure the one you choose is properly accredited. This will ensure that your education meets industry standards and will prepare you for the workforce.

Once you’ve completed your accredited CAD program, it’s time to start looking for a job. Many CAD jobs are found in the engineering and architecture industries, but there is also a growing demand for CAD technicians in other industries such as manufacturing and construction. To increase your chances of landing a job, be sure to brush up on your interviewing skills and have a strong portfolio of work to show potential employers.


Computer aided drafting (CAD) is an invaluable tool for those in the engineering and architecture fields. Not only does it significantly reduce the time and effort required to create technical drawings, but it also ensures accuracy and precision. With CAD, architects and engineers can bring their projects to life with greater efficiency than ever before. From 3D modeling of buildings or bridges to 2D schematics for machines, computer aided drafting makes sure that designs are executed accurately every time.
