Thanks turtle, the eBook software is almost finished. I am very happy with the security for the eBook. One copy per person, per computer, period. You can un-install it and put it on another computer but you can't run 2 of them on different computers. Security will not allow that.

I don't want to just release one or two to start I want a set of 6 books with plans finished before we start to offer one for sale. So more work to do but that's ok all it takes is money and time. Time I have plenty of.

Thanks for asking and for your ideas it's very kind of you.

Oh & powder puff yes I do own several legal copies of AutoCad the current version is 15 for the 3D version.
