IMSI/Design recently announced the debut of TurboViewer, a free app that allows fast viewing of native 3D DWG files on iPad and iPhone.

When you open a file in TurboViewer, it will autosense whether you have
opened a 2D file or a 3D file. If you’re in a 3D file it will change the
gesture slightly to optimize its usage.

The main point of TurboViewer, said CEO Royal Farros, is its performance, and
noted that on the 3G iPhone I had it was going to be a bit slower than
on a 4G, or on an iPad, but I didn’t notice that it was slow at all. For
orbiting, zooming in and panning a drawing you can use standard iPhone
commands such as pinch to zoom in and out, do a single finger navigation
to orbit around a drawing. If you have files that are on the web,
select those from your web browser and download those. You can also email yourself files that can be viewed in TurboViewer.
