circles are not accurate in Corel Draw X7 ???

I cant draw a perfect circle , always there is an unexact size  

what is the problem ??

  • mmm 1/1000 of a millimeter. try setting your dimensions to 2 decimal places.

    • Thx Chris , but it'll be still even if I made the ruler with 2 decimal places  ..I ve noticed that during drawing inside circles 

      • CorelDRAW circles are perfect if your use the ctrl key when drawing.  If you change the size proportionally they stay that way. If you have a circle inside another circle and they were drawn properly but look incorrectly it may be a display issue with the monitor zoom in and zoom out and watch.

        • I used to draw lines (same length as circle's radius )  from center    not all of them touch the circle !! 

      • What you are seeing is not necessarily a problem with the circular ellipse. It can result from the "imperfection" in how the end points of the dimension are placed. If they are placed exactly at the nodes of the ellipse, then you will get better results.

        • thx dear . but I used to draw multi  radius with same length from the center of circle   many of them  did'nt touch the circle !!

        • If you want an exact and accurate object, you can create it from the Object Coordinates docker. The size is exact, but if you rotate the object there's a small difference (surely due to the screen resolution. The difference is almost zero
