This software actually comes with the added benefit of being able to use the models for 3D printing. Not only can you draw in 2D space like you can with AutoCAD, but you can model in 3D space as well. This program will never cost you anything, and it can handle even the most complex CAD drawings. If you want something cheaper, SolveSpace, a free 3D parametric CAD program that is absolutely free, maybe for you. The company no longer develops Sketchup Make, its free desktop software, but you can download it from Trimble's archives.We’ve mentioned AutoCAD’s cost several times already, and that’s because it is a legitimate barrier for many users. The SketchUp website offers a really impressive array of video and self-paced training options to help you along the way. 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. Even if you've never done any CAD work or 3D modeling before, you can pull together some really nice presentations in minutes. The interface makes it easy to get up to speed on the basics. SketchUp's free web-based version has plenty of power, but if you need additional functionality, you have to buy SketchUp Pro-and pay a hefty price tag. Trimble has enhanced it and developed it further and now offers a slew of related products. In 2012, Google sold the product to Trimble. SketchUp was originally developed by Google and was one of the greatest free CAD packages ever put on the market.
