Informative Graphics's Net-It Enterprise 7.0 automatic document publishing software converts any size of AutoCAD, MicroStation, or SolidWorks drawing into a Microsoft Deep Zoom image.
Once converted, the images can be viewed on the Seadragon iPhone app, as well as through Silverlight and Seadragon AJAX. (Net-It Enterprise automatically detects when new drawings are saved by the CAD software, converts them, and then makes them available — including through RSS notifications.)
Even though the drawings are in raster format, the Deep Zoom technology makes them as zoomable as vector drawings.
You can download the Seadragon iPhone app free from the iTunes store, or try out the Silverlight versions at www.infograph.com/silverlight.
