Pretty neat, I'm not sure if it will be useful or not. It is \\\$1.99, so for people with iPads it is at least a good price for what you get. I'm still weary of its usefulness, without any direct link to PDM or a server based file structure. It seems to work best when using email to send files. Still, it is better than nothing, and could still be very useful. I see it being a great tool for sending to sales people to show to customers; they typically like email anyway. Here's the details:

Opens eDrawings, DraftSight, DWG, and DXF files.

3D model viewing, with a similar experience to the current eDrawings.

Store files through iTunes File Sharing

It's currently only available for iOS 4.3+ iPads.
