IMSI/Design has released TurboViewer Pro, a professional version of its free TurboViewer app for the iPad and iPhone. IMSI/Design modestly claims the new app is the “fastest and most capable 2D and 3D viewer on the iOS platform.”

IMSI/Design publishes several retail-priced CAD and related products, including TurboCAD and DesignCAD. It uses technology from the Open Design Alliance, the consortium that publishes the Teigha library of DWG-compatible technology used by many of Autodesk’s competitors. (See also the recent GraphicSpeak article, “The Open Design Alliance Prepares for the future.“)

The free version of TurboViewer was the first and only DWG viewer to support both 2D and 3D CAD DWG files for the iOS platform. Files are added to the iOS device by email attachment, Web download, FTP, Dropbox, WebDAV, iCloud, or other cloud-based storage systems.
