Don't get too excited though - according to early reviews, you need an AutoCAD account to even get inside AutoCAD WS, and the app cannot create new drawings - only open existing ones. Not too bad for starters though, considering all the available features. Not bad at all.
AutoCAD® WS is a mobile CAD application that gives you the freedom and flexibility to view, edit, and share your DWG™ files on your Android phone or tablet.
AutoCAD WS mobile app offers a simplified, intuitive set of viewing, editing, and markup tools so you can work on your designs while you are on the go.
Open drawings from email attachments, sync your files from the web, or upload drawings directly from AutoCAD software.
Drawings can also be saved locally so you can work in the field without an Internet connection.
Experience the freedom of taking your designs with you—wherever you go.
