It is possible to get AutoCAD for free if you’re in education. 8 Responses to Top 5 Affordable AutoCAD Alternatives. Dmitry Oct 23. But no doubts the Autocad LT is best 2d software and Autocad is a best 3d to me. Other problem is subscription policy: 60 e month for LT is fine but 220 e for Autocad is a bit too much for freelancers if. (Best Free CAD Software) Computer Aided Design — generally alluded to as CAD — has turned into a fundamental variable that propels world, from numerous perspectives. As a mechanical workmanship, CAD let us create designs for an extensive variety of purposes, from designing a small electronic hardware to sufficiently huge machines. Computer Aided Design, or CAD stands for any software that allows architects, designers, profilers and artists to recreate perfect scaled models, designs and graphs or diagrams in 2D and 3D with the use of a computer. There is however a second option: free alternative CAD software. We have done the legwork and looked for the 10 CAD software that you can try for free now to design your next 2D drawing or 3D modeling project. Here are but just 10 of these software, and the links to download them for whichever operating system you are currently on.
Everyone loves to get something for free, but if that something doesn't do what it's supposed to.. it's still overpriced. On the other hand, if it's free and it's just what you're looking for, it's like finding money in the street. If you're looking for basic CAD software packages and do not need highly technical functionality, you likely will find all you need, and maybe more, in one of these four quality packages that you can download for free.
AutoCAD Student Version
What We Like
Part of the Autodesk family of modeling applications.
AutoCAD is an industry standard.
What We Don't Like
Watermarking on the free software editions.
Full-featured and more complex than other programs, not newcomer-friendly.
AutoCAD, the heavy hitter of the CAD industry, offers a free, fully functional version for download to students and faculty. The only limitation on the software is a watermark on any plots you generate, designating that the file was created with a non-professional version.
Not only does Autodesk offer its base AutoCAD package free, but it also offers free licenses for almost its entire suite of AEC vertical packages, such as Civil 3DAutoCAD Architecture, and AutoCAD Electrical.
If you're looking to learn CAD or just do some personal design work, this is absolutely the way to go.
And I didn't upgraded from previous version. 
I have the latest version of AS from the android studio website. Its a fresh install. I successfully downloaded it and I can run with./studio.sh from /opt/android-studio/bin.
Trimble SketchUp
What We Like
Clear features grid comparing paid-versus-free features.
Options for home hobbyists to industry professionals.
What We Don't Like
Pricing model isn't great.
Free feature is web-only with many important features hobbled.
SketchUp was originally developed by Google and was one of the greatest free CAD packages ever put on the market. In 2012, Google sold the product to Trimble. Trimble has enhanced it and developed it further and now offers a slew of related products. Its free version SketchUp Make has plenty of power, but if you need additional functionality, you can buy SketchUp Pro — and pay a hefty price tag.
Best Free Mechanical Drawing Software
The interface makes it easy to master the basics. Even if you've never done any CAD work or 3D modeling before, you can pull together some really nice presentations in minutes.
Of course, if you're looking to put out detailed designs with accurate sizing and tolerances, you'll need to spend some time learning the ins and outs of the program. The SketchUp website offers a really impressive array of video and self-paced training options to help you along the way.
Free Cad Software
FreeCAD
What We Like
Well-supported open source platform.
Ideal for engineering.
Well-optimized for 3D work.
What We Don't Like
Best Free Mechanical Cad Software
Clunky to work with.
2D features aren't great.
FreeCAD is a serious Open Source offering that supports parametric 3D modeling, which means you can modify your design by going back into your model history and changing its parameters. The target market is mostly mechanical engineers and product design, but it's got a lot of functionality and power that anyone would find attractive.
Like many open-source products, it has a loyal base of developers and can compete with some of the commercial heavy hitters because of its ability to create real 3D solids, support for meshes, 2D drafting and lots of other features. Further, it's customizable and is available on multiple platforms, including Windows, Mac, Ubuntu, and Fedora.
LibreCAD
What We Like
Free and open-source.
Excels at 2D work.
What We Don't Like
Not as strong for 3D work.
The website focuses on stuff that matters to app developers, not to CAD users.
Another Open Source offering, LibreCAD is a high-quality, 2D-CAD modeling platform. LibreCAD grew out of QCAD, and, like FreeCAD, has a large, loyal following of designers and customers.
It includes lots of powerful features that include snap-to-grid for drawing, layers, and measurements. Its user interface and concepts are similar to AutoCAD, so if you have experience with that tool, this should be easy to master.
