Golly working on Sunday is fun!
The client has some cheap program he fond on the internet for free to work with the files we send him. Instead of buying a expensive professional program he is doing it cheap. We make the files in US feet, and a one foot resolution, since that is all he wants to pay for and can handle. Higher resolution would be 4 times bigger files for 6 inch resolution. Anyway I just spent a few few hours converting everything from on foot to 12 inches.

That way his program reads it is right. Every ruler I have is shows a foot as 12 inches, but not his freeware.
