4 Best free cad app for iOS and Android

We recently introduced some 3d modeling APPs that work on smartphones. These APPs can be used to create 3d models. But sometimes we don’t need 3d models, and we just need 2d cad files. For example, if you have a laser cutting business, you will find technical 2D drawings are more suitable. Then a free cad app will be a good help.

There are many 2D drawing software packages that work on Windows or Mac systems, such as Auto CAD, CAXA, and more. We won’t talk about these tools here. We focus on free cad software that can work on mobile. And now some smartphone is powerful enough to run a 2D drawing APP.

When you want to edit 2d drawing with a mobile APP, it is a good method to connect a mouse to your smartphone. But keep in mind, they are only some tools to help you when you don’t have a PC on hand. So, if you want to do 2d cad jobs efficiently, desktop software is necessary.
