Actually, they collaborate closely with LibreCAD, the previous AutoCAD alternative on this list. For example, LibreCAD operates under the umbrella of BRL-CAD in Google Summer of Code and Google Code-In. BRL-CAD boasts 30 years of deployment. It is a cross-platform solid modeling system with features like:. Hybrid CSG and B-rep kernel. High-performance ray-tracing. Extensive geometry libraries. BRL-CAD can boast of something that not many other alternatives can lay claim to: It is used by the US Military. Yes, the US Military uses the BRL-CAD platform for weapon system modeling. Using BRL-CAD, the US Military is able to test the lethality and potential vulnerabilities of various weapons. As mentioned, BRL-CAD has been around for three decades. It was first released in 1984, and it first became open source in 2004, but it was first started all the way back in 1979. BRL-CAD is cross-platform, as mentioned. Not only is it available for Windows, Mac, and Linux machines, but it can be used on BSD, Solaris, and other platforms.

NanoCAD is a free CAD software alternative to AutoCAD, with a catch – if you use the free version, you can only use it for educational and evaluation purposes. That will be enough for many people searching for a free AutoCAD alternative. You don’t need to register an account to use the free version. However, using the free version, you can’t use it for profit or commercial purposes. NanoCAD is a great alternative to AutoCAD because it has many of the same features, in addition to some features that AutoCAD does not have. Here are some examples of AutoCAD features that NanoCAD has as well:. Multiple document mode. Auto recover drawings. External references. Some features that NanoCAD has that AutoCAD does not include:. The ability to create a viewport from model space. A line-type editor. The ability to preview undos and redos (only the premium version of NanoCAD offers this feature). Since NanoCAD supports DWG files, you can use drawings from NanoCAD in other CAD software without doing any tricky conversions. DWG is the industry standard, after all. The Excel-style table editor and comprehensive command set are two more reasons why I think NanoCAD makes a great AutoCAD alternative. Also, NanoCAD has different API types, which allow you to build applications and add-ons for additional functionality and more features. Again, although NanoCAD is free to use without a purchase or subscription, it does require a license to be used for commercial purposes. However, it is much cheaper than AutoCAD, with licenses and plans starting at just $180/year compared to AutoCAD’s $220/month – check the NanoCAD purchase page for updated pricing information, as prices are subject to change.

For a full list of NanoCAD tools and products, go to the products page – however, keep in mind that those other products only offer a free trial. Interesting Post: Best Adobe Animate Alternatives.

Like LibreCAD, QCAD is a free and open-source software for two-dimension modeling. So, if you are looking for a free alternative to AutoCAD for 2D modeling only, consider using QCAD. One of the things I love about QCAD is how simple and easy it is to use. The interface might not look the most modern or be the fanciest, but it is incredibly intuitive and easy to figure out, even if you have never used QCAD before. Some of the awesome features you can take advantage of when using QCAD include:. Print on multiple pages. Group with blocks. Use up to 35 CAD fonts. Use up to 4,800 CAD parts from the library. Many more features. QCAD is available on Windows, Mac, and Linux devices. You can go to the download page to download the free version of QCAD. By default, that comes with a free trial of the Professional version as well – the free trial allows you to work using the Professional version for up to 15 minutes at a time. In other words, you can use the Professional version for free as many times as you want – but you can’t use it for more than 15 minutes. If you can complete your work in 15 minutes, you will have no problem; you can restart the Professional version every 15 minutes. However, if you want, you can only download the free version and not deal with the Professional version or its free trial at all. Remember, QCAD is not only free but it is open-source, meaning the source code of the free version is public and available to all.
