ABSOLUTE COORDINATE SYSTEMS IN AUTOCAD 

Dear As Point A is the origin, So all the movements on the right side of the origin will be taken as positive. As this is Absolute coordinate system(origin fixed). but if we working in relative coordinate system,(in this origin is not fixed) then we will take it in negative x Axis. hope u got the answer..... u can see the below video of Relative coordinate system.. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IPHquDpGiss.html

Yes sir I have seen the your relative coordinate system video due to which I was confused

Sir you have say that any movement at right side is taken positive but in point C to D we are moving to left

but it is the Absolute coordinate system.... hope u got it now
