Go to the download page to download the free version of Draft It both bit and bit versions are available.
When you download the free version, you will also be downloading trials of the three other versions of Draft It: Plus, Pro, and Architect. Those three other versions can be used for up to 15 days. Once those 15 days are over, you can continue using the free version of Draft It without any limitations. It is free and available for Windows, Mac, and Linux devices. The LeoCAD software is compatible with LDraw tools, and it also makes use of the LDraw library, which has over 10, parts you can add to models and designs.
LeoCAD is not only free, but it is also open-source. As such, everyone can contribute a fix or repair a bug. The reason for this is that SketchUp is a much simpler tool, and CAD models can often be too complicated for SketchUp modeling, leading to various complications. One thing I like about SketchUp over its alternatives is that everything is done in the cloud.
In other words, you access the work area from your browser, on the web, without downloading any software. That allows you to get to work right away and save time and space on your device. There is even a mobile app that allows you to view 3D models on your phone. To get started, and to see premium plans you can upgrade to, click on this link.
Vectorworks is not free for everyone, but if you are a student or educator, you will be able to use it for free. If you are a student, visit the Vectorworks Academic Portal to get a free academic license — if you are a professor, you can use it too. Also, if you are looking for an AutoCAD alternative for your entire class or school, you may be able to get a free version — go to the education page to learn more.
It is a complete design, sketch, and modeling tool. However, you will need the ConnectCAD add-on. Go to the ConnectCAD page to learn more.
In addition to these free CAD software options, there are various pirated versions of premium CAD software floating around the dark web. However, I would recommend that you stick to legal free options, including open-source options. It is not legal to use pirated software, but the problems of using pirated software go beyond that. Many sites that offer pirated software sneak malware, adware, and viruses into the download packages, and you may be downloading some bad stuff along with the pirated software.
Also, many of the websites are somewhat sketchy and have many pop-ups and redirects, which can also lead to adware showing up on your computer. If you need a better CAD software tool for one-time usage, I would recommend finding one that offers a free trial. In addition to some of the software in this list that offer trials for their premium versions, you can find many other premium CAD software that provide free trials, such as:.
As you can see, there are many awesome AutoCAD alternatives, regardless of why you need one. Most of these options allow you to migrate your work from AutoCAD, depending on the types of file formats they support. It is not only free but open-source too, and it has a really awesome community behind it.
There is a lot of documentation online, and it is also easy to get help. Editor's note: This article was originally published in May , and has been updated to include a few additional options. CAD—computer-aided design or computer-aided drafting, depending on who you ask—is technology created to make it easier to create specifications for real-world objects.
Whether the object you're building is a house, car, bridge, or spaceship, chances are it got its start in a CAD program of one type or another. So how do the open source alternatives to AutoCAD stack up?
The answer depends on how you plan to use them. Let's start by being honest and upfront about something: If you're looking for a drop-in replacement for your existing CAD program that will provide identical functionality and workflow without making any changes to your processes, you're going to be disappointed.
But I would argue that the reason for your disappointment has nothing to do with the licensing of the product—drop-in replacements for complex programs with long-time users who have specific needs and expectations for their software are hard. The trick for deciding whether a replacement piece of software, whether open or closed, is a good choice for you is to tease out exactly what your needs are.
The situation is no different than discovering that the person who insists that they "need" Photoshop is just using it to draw a few geometric shapes and remove red-eye from photos; what they really need is a graphics editing tool that can replace those specific functions.
Whether it has all of the bells and whistles of the original is irrelevant if those features sit paid for but unused. My personal journey through open source CAD programs was no different. I worked with AutoCAD briefly in grad school, so when I wanted to play with drawing three-dimensional plans for something, it was pretty much all I knew.
But that alone didn't make AutoCAD the best choice. As I've strived to replace more and more software in my life with open source options, Blender turned out to be just as good for my 3D modeling needs, whether I was playing with models created for a 3D printer or looking at landscapes exported from other programs.
And for the relatively simple task of planning out my home landscaping projects, Sweet Home 3D has been an excellent open source alternative. If your needs are a little more specific and you really need a dedicated CAD program, here are great open source choices to consider:. It's a side-project of the 3D powerhouse, OpenCascade , and has some serious industrial users.
It has integrated Python support. As with all other CAD applications on this list, it's open source, so if you have in-house developers creating plugins for it, there's no need to deal with a clunky API. You have direct access to the code base. BRL-CAD is a cross-platform CAD tool that dates back to , although it would take 25 years for the source code to be released under an open source license.
In fact, BRL-CAD is so old that it has been credited with being the oldest source code repository of an application currently in active development. Originally developed by Mike Muuss at the Army Research Laboratory, BRL-CAD is been used for decades by the United States military for modeling weapon systems, but it also has been used for much more everyday design tasks, from academic to industrial design to health applications. So what does more than 35 years of development bring you?
BRL-CAD is made up of more than different constituent tools and applications spread across more than a million lines of source code. FreeCAD is a parametric open source CAD program that was created to be able to design "real-life objects of any size," and although it's clear that many of the showcased examples created by users are smaller objects, there's no specific reason it couldn't be used for architectural applications as well.
FreeCAD can import and export from a variety of common formats for 3D objects, and its modular architecture makes it easy to extend the basic functionality with various plugins. The program has many built-in interface options, from a sketcher to renderer to even a robot simulation ability.
Currently in beta, FreeCAD is being actively developed with regular releases, but the developers warn that it may not yet be suitable for production use. LibreCAD is 2D only, though, so it makes more sense if your intended use is a site plan or something similarly, err, flat. Since we can't include all of the options here, if you have a favorite, let us know in the comments below. Are you interested in reading more articles like this?

The beauty of Linux is Linux itself, and the apparent obsession many users have to also use only OSS on it, is limiting their use of their computer, and is a loyalty of open source, that seems far beyond the philosophy the Linus and the Linux kernel.
It even uses most of Autocad's same commands. BricsCAd also has a large community using the product. As a 20 autocad user, it only took minutes for me to get up and running with BricsCAD.
I would hazard a guess that most readers of opensource. You simply code objects -- after a little bit of a learning curve to remember the basic commands it becomes an incredibly powerful parametric design tool.
