If you work with AutoCAD and have an Android device, it can not miss the free AutoCAD WS, which enables you to take your designs anywhere you go. Last Monday was updated, and incorporated features of geographical position by GPS, with 3D interactive visualization.
AutoCAD WS enables us to see and share as many files as you need DWG and work with them in our tablet or smartphone, with or without an Internet connection. In the latter case, the application saves a local copy on the device.
We review all aspects (layers, external references, image underlays …), modify objects, use the zoom to navigate larger drawings, etc.. We even have the option of working on the same file with other people simultaneously.
It also allows us to open DXF DWF and projects, and share them via email, and print remotely to the service designs ePrint & Share, HP. Requires Android 2.1.
