One of the more popular online educational programs is learning the basics of the CAD (computer-aided design) application. Students learn how to use the 3D technology as a trusted ally inside the workplace. The software is very popular among engineers, researchers and designers as it can expand a simple drawing into a very detailed layout. The 3D drawing offers dimension and detail that represents a real-world look to the design.

Before choosing to become a CAD designer, it is important to understand the current landscape in the industry and see where the application has evolved from. 

The History of CAD

In 1949, the invention of CAD was created to design circuits by using basic geometric shapes. Many believe the history of CAD closely parallels the evolution of the computer. Together, they revolutionized the engineering, architecture and construction industries. 

It would take over a decade before CAD would be accepted as an useful design tool. The concept was enhanced by Ivan Sutherland in the 1960s. He developed a computer program (Sketchpad) that offered the basic fundamentals of technical drawing to designers. Sutherland’s software allowed users to feed their sketches into a computer by drawing on the CRT (Cathode-ray Tube) monitor with an ultra-violet light pen. 

CAD is a Fundamental Part of Designing

Before the advent of the CAD application, all designers used was a draft pad and pencil to create their drawings. However, once the software was implemented into the workplace, every firm needed an expert on staff. Today, the use of the CAD application isn’t limited to large corporations as small firms can create elaborate designs in the confines of their limited office space. Now, they can convert a series of preliminary sketches into a very detailed 3D design in a matter of minutes. 

CAD has replaced manual drafting by helping to visualize a drawing in a detailed manner. Companies employ CAD designers because they save time and energy with their quick productivity. In today’s world, it is all about drawing wiring diagrams, circuit board configurations and architectural floor plans.

Over time, CAD designers will increase a firm’s productivity and efficiency. The new designs help project engineers to make the necessary modifications to the original drawings. Easy access to the new drawings allows the construction team to view the changes that need to be made in real-time without delay.

Online Classes is the Best Approach to Becoming a CAD Designer

Online coursework is the best approach for those who want to be CAD designer. Students are able to select their own course study programs including the necessary follow-up classes at their own discretion. All of the subject matter provided will help you to keep pace with the global technological advances in creating elaborate designs and drafting detailed blueprints. 

First, CAD is not an easy program to learn. Other applications may have a higher learning curve, but not CAD as it’s due to the complexity of the program. Thus, the commitment to learning 3D design will take a quite bit longer than other applications. Past graduates believe CAD is a lot like learning a foreign language. For success, it is all about retention and memorization of the materials until it is part of your vocabulary.

The best approach to leaning the application is repeating each class exercise at home. It might take a bit longer, but it will help to familiarize yourself with the 3D design process. Continuous repetition of the commands will eliminate any hesitation on your part when creating an elaborate blueprint. After awhile, you will gain confidence to create bigger and better designs, instead of worrying how to operate the CAD program.

The introductory classes offer the fundamentals of CAD as the subject matter is taught in a manner where the teacher challenges the students with completing relevant tasks that are found in the workplace. It will help them to learn the disciplines of engineering and architecture. Typically, each class tutorial is approximately two hours of coursework. As you progress through the online CAD program, some of the completed coursework will award certificates that can be used to verify your experience.

Even experienced CAD designers will continue to use their learning software program at the workplace. It is a great resource for those designers who want to visualize a sample 3D design before sharing with others. Quickly, you will learn the software’s best asset is assisting with improving your design capabilities while working in the simulation icon. Once you gain the experience there is no limits to how far you can go within the industry. 

If you are thinking about beginning CAD education, then it would be wise to create a study plan for yourself. Take the time to jot down your own objectives to learning this application. Try to include the amount of time to be allotted for studying and training. The demands of learning CAD is very time-consuming and is not for every student.
