This has promise! – iPocket Draw Review

For an only offering of its kind, this program is really quite good. It will be interesting to see just how may features the author will be able to put into such a small package. Don't expect to draw large complicated presentations with it, but it is a good place to put your thoughts down in vector form. Another reviewer had problems exporting the drawing to .dxf; I was able to import a file into Vectorworks. Not the easiest, but it did work and I was able to take some germinal ideas and expand them.
