On Oct. 5, Autodesk reported 255,000 downloads of its AutoCAD WS Mobile app for the iOS operating system in the first five days of availability as a free app from Apple’s iTunes store. The app lets Apple iPhone, iTouch and iPad device users view, edit and share AutoCAD and DWG files through web browsers and mobile devices. More than 100,000 files were uploaded to sharing servers in the first days. “It’s an amazing response,” says Amar Hanspal, senior vice president of Autodesk platform solutions and emerging business. “We can’t add servers fast enough.” He says the application is engineered to support other mobile platforms in the future, including Android and Palm devices. “The use of mobile devices is exploding, especially in construction,” Hanspal says. “It’s a very strong match.”
