Darn, I finished coding only to discover the "putdxf" I use for my CAD import has a bug that fails to locate multiple blocks correctly. I confirmed this by being unable to "putdxf" with the system's "getdxf". Will have to rewrite as a "command line" script. Thanks for everything, sorry I couldn't understand much of what you tried to explain to me. But, because of your help, I will get better in time
