AutoCad 2D :: How To Get Geometry Information In Properties

once I've set an origin, how do you get the geometry info in the properties to show the coordinates from that origin? what I want to do is set an origin and then find relative points from that origin. What are the ways to do this? On ProgeCad I would just set an origin and then if I viewed the properties of say a circle, it would tell me the x,y,z coordinates from that origin but I can't seem to do it in AutoCad.

As you can see from the picture, what I did was set an origin at the on point. Then I selected the arc for which I want to know the coordinates. But as you can see in the properties it says the x,y are like 566,567mm, but clearly if I draw lines to that point and measure the lines it is only like 1.00,0.70mm.
