Autodesk Factory Design tool based on AutoCAD 360 in iPad is on App Store now. You can get it by search "Autodesk Factory Design” in App store. It is free.
Layout designers can drag and drop factory 2D assets to start the 2D layout design in iPad.
Then they can get the dwg file on desktop AutoCAD by Autodesk 360 sync.
Please enjoy it and welcome any feedback/comments to the App.
I realized shortly after posting this that it didn't show up because I was searching the app store on my iphone. A web search on my phone took me to a link that informed me that this is an iPad only app.
