CAD or Computer-Aided Design replaces the concept of manual drafting by an automatic process. CAD can be used by professionals in structural engineering design, interior design,  architecture, automobile design, product design, fashion design, etc.

While CAD packages were in use for more than a decade, now, the trend has shifted to 3D CAD software that can work on different dimensions. This allows the drafters to rotate the object views smoothly, and to observe it from different angles.

CAD tools are used by architects, drafters, or engineers to prepare the illustrations for several types of design requirements. The top CAD software comes with varied features that allow you to develop high-quality designs. But you must shortlist and use the one that matches your requirements well.

There are several CAD software available for popular CAD applications. To make a good selection, though, you must understand CAD well. 

What is CAD?

CAD or Computer-Aided Design is used in computerized drafting in various industries. It is computer software that helps you in making high-quality 2D or 3D models.

Across several occupations, CAD software helps in preparing the building plans, electrical schematics, mechanical drawings, technical drawings, blueprints. It can also be used to create special effects for TV shows or movies. 

Benefits of CAD

Traditionally, industrial design was manual, and so the designs were prepared on paper. The lines, curves were set using instruments such as rulers and protractors. Moreover, it required the designer to do lots of manual calculations.

Thus the manual design process was very time-consuming and error-prone. And errors were very difficult to correct, at times requiring the designer to repeat the whole exercise.

Now, CAD software has changed the process for the better. The designs created by CAD are easy to edit and require less time to create. It also helps you prepare designs in both 2D and 3D and view it from different perspectives.

CAD also helps in proportioning and calculations that are a part of the design. The design can be shared in real-time. The other significant benefits of CAD are as follows.
