Tinkercad is a free, easy-to-use web app that equips the next generation of designers and engineers with the foundational skills for 3D design and printing.
Tinkercad can be run on Windows, Mac, Chromebook, iOS (iOS 11+) and Android (7.1+). It works best on a device with a large screen like a laptop or tablet. Full system requirements are below.
TinkerCad is a great launching point for people of all ages to get into 3D design. Even though it is a simpler CAD program, it is very powerful because it makes it quite simple to make functional parts. By grouping shapes and cutting holes, you can make fairly complex shapes that measure out to the millimeter.
