Computer-Aided Design (commonly referred to as CAD) has become an integral factor that moves the world forward. CAD lets you design everything from tiny pieces of electronic equipment to large buildings, dams, and more. Naturally, CAD programs have become expensive as most professionals use them to design things. And if you are a student or a freelancer, buying expensive CAD software becomes a distant dream. But there is nothing to worry about as we have curated a list of the top 10 free CAD software which are as good as the paid ones. So without any delay, let’s check out the best free CAD software in 2021.

Best Free CAD Software (Updated March 2021)

Here, we have compiled a list of the top 10 free CAD software you can use in 2021. The list includes two kinds of software – the free ones and the Student’s edition of premium software. The latter will be useful when your institution uses a particular tool, and you need to use that too.

1. FreeCAD

FreeCAD, as the name suggests, is a free and open-source CAD software, and it’s a top choice among both beginners and professionals. If you are well-versed with CAD modeling basics, then this software would be the best pick for you. An educator or programmer can also get the best out of FreeCAD, given its multi-purpose behavior and intuitive interface.

Despite being a free tool, the UI of FreeCAD is almost on par with professional CAD software. It also packs in a ton of features. Probably the most significant feature of FreeCAD is the Parametric Model. It lets you go back and edit your actions so that you get the best results. The software also has a modular architecture, enabling you to install plug-ins for additional features you need.
