Interscale Content Hub – The pros and cons of open-source CAD tools are a topic of conversation for anyone involved in computer-aided design.
In recent years, open-source CAD tools have become popular because they are cheap, flexible, and easy to use with others.
But like any software, they have pros and cons. Let’s look at open-source CAD tools and see what they can do for you.
What are Open Source CAD Tools?
Open-source CAD tools are free software for creating 2D and 3D designs. Open-source CAD tools are free, unlike proprietary CAD software that often comes with high licensing fees.
These tools are developed and maintained by a community of developers, who make improvements and add new features based on user feedback.
L. Jin, C. Liu, and M. Anan in their study “Open-Source VLSI CAD Tools: A Comparative Study” highlight how important CAD tools are for designing electronic circuits. As circuits get more complex, CAD tools are needed.
They also note that the right CAD tools for academic use are essential because many commercial options are too expensive and require high-performance platforms.
Similarly, Stefan Junk and Christian Kuen in “Review of Open Source and Freeware CAD Systems for Use with 3D-Printing” discuss how open-source CAD tools have helped 3D printing.
These tools have made CAD capabilities more accessible, allowing students, hobbyists, and professionals to engage in complex design and manufacturing processes without significant investment.
Features to Look for in Open Source CAD Tools
When choosing an open-source CAD tool, consider these features to make sure it meets your design needs.
Platform Compatibility
Just make sure the tool works with your operating system, whether it’s Windows, macOS, or Linux.
According to Junk and Kuen, making CAD tools compatible with multiple platforms makes them easier to use for a wider range of users.
This means users don’t have to change their operating systems to get started.
File Format Support
Look for tools supporting a bunch of different file formats, like DXF, DWG, STEP, and STL.
This makes sure it works with other CAD software and makes it easy to share data.
For instance, FreeCAD supports a bunch of different file formats, including STEP, IGES, and STL, which are key for making sure your designs can be used with other design systems.
User Interface
A user-friendly interface can make it easier for beginners to learn, especially if they’re new to CAD software.
As Jin, Liu, and Anan pointed out, tools like Electric and Magic have intuitive interfaces that make it easier for users to navigate complex design tasks.
These interfaces often include visual guides and interactive elements that make the design process easier.
Community and Support
A strong community and lots of helpful documentation or tutorials are great for troubleshooting and learning.
Open-source projects like Blender really benefit from active communities that provide lots of tutorials, forums, and user-generated content.
This makes it easier for new users to get started and for experienced users to find advanced solutions.
Customization and Extensibility
Tools with customization and plugin support can be tailored to specific needs.
For instance, FreeCAD’s modular architecture lets users add functions and open-source libraries without changing the core software, which gives them flexibility and extendibility.

Top Open Source CAD Tools in 2024
FreeCAD
FreeCAD is a flexible, open-source parametric 3D CAD modeler that’s great for all kinds of applications, including product design, mechanical engineering, and architecture.
It supports several different file formats, such as STEP, IGES, STL, and DXF, so it can be used with other CAD tools.
FreeCAD has a solid parametric modeling system that lets users tweak designs by adjusting parameters. It also has a modular architecture that lets users customize and script through Python.
LibreCAD
LibreCAD is a free, open-source 2D design app. It’s cross-platform and supports DWG and DXF file formats, so it’s a great choice for hobbyists and professionals who need a simple tool for technical drawings.
LibreCAD’s user-friendly interface makes it easy to create detailed 2D designs, and its community-driven development means it’s always getting better and getting support.
Blender
Blender is a pretty versatile open-source 3D graphics software that’s used a lot in game development, film production, and 3D printing.
It’s great for modeling, texturing, and animation, with a full set of features including sculpting, rendering, and simulation tools.
While Blender is pretty powerful, it can be a bit tricky to get to grips with at first.
Blender supports a bunch of different file formats, so you can easily integrate it with other design and animation workflows.

BRL-CAD
BRL-CAD is one of the oldest open-source CAD tools, and it’s mainly used for engineering and scientific applications.
It’s got some pretty powerful Constructive Solid Geometry (CSG) modeling capabilities and supports a bunch of different file formats.
However, its interface isn’t as intuitive, so it’s better for users who have specific technical needs and a background in engineering.
QCAD
If you’re looking for an efficient and easy-to-use open-source CAD system for creating technical drawings of buildings, mechanical parts, or diagrams, QCAD might be a good fit.
It supports DXF files, which are pretty common in the CAD industry, and it’s got a really easy-to-use interface.
QCAD is ideal for users who need a simple 2D CAD solution without the hassle of 3D capabilities.
