Thanks for the clip sir, it works on other files that already created units precision but when i start from scratch the line scale doesn't change and still nothing happens.  

Does the're any option how to change it?..thanks alot

Set it all up then Save as Template drawing and use it to start a new drawing.

Thanks for your help sir, now I get it. When I start from the scratch and use default metric unit it wont work, but when I chose feet and inches to default it really works and save it as a template. Now I can adjust the units without worrying it. Thanks alot
