Is there a 2D drafting app that will work with iPad?

Currently I teach a basic drafting course for aviation maintenance technicians using Ashlar's Graphite. I am interesting in eliminating my classroom/computer lab and going to student-owned ipad 2s. I need to be able to teach basic CAD drawing. Is there an application that will work successfully with the ipad 2?

Thanks,
Fred

I have used Sketchbook from AutoDesk - http://itunes.apple.com/us/app/sketchbook-pro/id364253478?mt=8

It's very good for sketching, but I understand you need something for drawing.

I came across this Fred but haven't tried it yet.
