10 Best Free CAD Software in 2021 (UPDATED LIST)

ADVERTISEMENT

Have you ever thought about bringing your imaginations to reality? It is now possible with the aid of additive manufacturing. However, you will need CAD software for creating, modifying, analyzing, and optimizing a 3d design.

Previously, this CAD program was used to create organic designs for animated films and video games. Now, with the advancement in technology, they are used by all designers, engineers, architects, and professionals for visualizing their ideas.

There is plenty of free CAD software available in the market. However, not all of them are feasible to create a 3d model. In addition, many of them that enable you to do so are not suitable for beginners. They vary in their complexity levels. Thus, it is difficult to choose one that suits your expertise.

For beginners, it is best to start one that is user-friendly. In addition, it should be simple to understand and easy to use. They should focus on basic learning and then move to complex software once they have mastered it.

Moreover, it is frustrating to invest days and time in learning complex software and wait to start 3D designing when you have little or no experience.

To overcome these challenges, we have listed the top free online CAD software that offers flexibility to first-time users. You can easily select one that matches your capabilities and printing goals.

What is a CAD Software?

CAD program stands for Computer-Aided Design. This technical tool aids the development, modification, and optimization of the 2D or 3D designs using computers.

For 3D printing, CAD software enables users to design 3D models with highly specific details that include dimensions, material properties, tolerance, and printing process information. You can save this file in the STL (Stereolithography) format, a de facto file format, for additive manufacturing.

Some CAD software offers various advanced features to professionals for better visualization of the product’s design. They also provide functions specific for mechanical designing, architecture, aerospace engineering, astronautic, and industrial designing.

Enthusiasts and Domestic users can also use it to create 3D model designs that they can use to 3D print with their FDM or SLA 3D printers.
