Can't use feet anymore only inches lenght works

[Anonymous]

Hi, 

For some reasons (and it's very possible that i've touch someting that i should'nt) i can't use feet (') distance for move, line, rectangle tools. I can only enetr the inches dimensions. My units are in Architectural. I put the symbol (') after my lenght. And it doesn't work, Please help me!

Exemple of command that i try to do: DP-Clic on the line that i want to move-Entrer 3' - The command line tell me that the point incorrect. 

It doesn't happen with all of my Autocad documents. And it switched while i'm using it. 

I noticed that after the Ortho label on the screen, the number is in decimal for the documents that i have problem with, and is in fraction when the document is ok. How can I change this set up?

Thank you!
