A pretty good tool for simple 2-d technical drawing and drafting

To start with, no one should be expecting autocad performance on an Ipad at this price.

That being said, I have used iDesign to create a number of plans and drawings, and have found it to have good functional performance, thoughtfully presented toolbars, and reasonably intuitive user operations. The learning curve is not that steep, and the user manual is pretty helpful (I did not try the video tutorials - didnt need them). I did not encounter the problems with iDesign that other users have found.

Not sure how big the user community is, but there are a few little items that could/should be addressed in the longer term, and the developer ought seek some input on this. Nonetheless, I looked at several technical drawing programs for the Ipad, and iDesign appeared to be the best program for general technical drawing purposes.
Definitely worth the price.
