COMMANDS FOR 2D AUTOCAD

whenever you have installed the Auto Cad, you must have an need to setup the dimensions first.Let's move toward the Auto Cad and open the window, type un and press the enter. you have showing window like this..... 

after change the dimensions decimal to engineering and 0'0'' you need press OK.
