You could enroll in a community college online course and learn how to CAD.

Too complicated?

How about EasyDraw?

Or.....

Intaglio makes a decent drawing program.

Or find an old iMac (or PowerPC) and boot up a copy of MacDraw in the classic OS environment.

Works pretty well for me.

Lastly, ship all the stuff to me and I will place it alongside the 100+ file boxes of ARC material I am archiving.

The choices are literally endless!
