I cant draw a perfect circle , always there is an unexact size
what is the problem ??
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 !!
