CAD, or computer-aided design, refers to the use of computers to design or technically document with an automated process. In the design industry, architects, designers, drafters, and engineers use 2D or 3D CAD software to draft construction documentation, visualize concepts with photorealistic renderings, and preview the unbuilt.

Today, we’ll introduce some of the free CAD software with their merits and features. Hope this article will help you meet the best free CAD programs to get amazing 3D models and 3D prints for your project!

 

Best Free CAD Software

 

Here we’ve summarized the information including the pros and cons of each free CAD software:

 

#1. Autodesk AutoCAD

Pricing: Free 30-day trial, or $1,865 per year.

OS: Windows, macOS, Linux, and mobile apps available.

 

Architects and designers use AutoCAD for both 2D and 3D designs. With free AutoCAD software, you can product design, do simulations of the structure, and create incredible accurate 3D visualizations. If you’re wondering whether this is the right software for your expertise, we’ll say AutoCAD is suitable for both beginners and professionals.

AutoCAD allows its users to set dimensions on the drawings, and build them automatically based on the given dimensions. At last, the result can be immediately printed on 3D printers, exported to any social networks, or just share by e-mails. On top of this, you can enjoy a connected design experience on any device, including desktop and mobile. The interface is user-friendly and easy to use, and we believe it is one of the best free architectural software.

 

#2. FreeCAD

Pricing: Free.

OS: Windows, macOS, Linux.

 

FreeCAD is an amazing drafting program with an open source and a simple interface. Because of its extensive functionality, FreeCAD is a good choice for both beginners and professionals. However, it requires knowledge of Python language if you hope to develop professional projects. Therefore, it is one of the best drafting programs for simple and basic designs.

This free CAD program reads and writes to many file formats including DWG, DXF, PDF, SVG and other popular formats.

 

#3. TinkerCAD

Pricing: Free.

OS: Online.

 

TinkerCAD is an online application, which means you can access it easily on your browser instead of downloading the program. Besides, it is super user-friendly because this best free CAD program has an easy-to-understand approach to shape 3D models. How it works is that you can create the object you want by placing blocks one by one.

The best thing of TinkerCAD is that it allows you to juice up your ideas without any 3D modeling or drafting experience. Thus, it is an ideal CAD program for beginners.

 

#4. SketchUp

Pricing: 30-day free trial, or $699 per year.

OS: Windows, macOS, Linux, and mobile apps available.

 

SketchUp is a well-know and widely-used professional CAD software, especially for architects, interior designers, and engineers. It offers more than professionally-developed drafting, you can also enjoy creating 3D models and document 3D ideas in 2D.

Another merit of SketchUp is that it has hundreds of professional extensions to create an instinctive 3D experience. At the same time, this best free CAD software is equipped with an open-source library with a large collection of 3D models. In this way, you’re free to choose and use the right model for your project. At last, the SketchUp Free is a web platform which is totally free for personal use and students!
