Question
why is that ever Circle i draw in AutoCad 2008 will appear like spider web look after i review again?
i try upgrade my graphic card to better one and review it again, the spider web ( circle ) become smoother bout still is not exactly a circle that i draw.

Answer
Victor, your graphics card has little to do w/ the circle object. Typically when you work w/ autocad & start compiling several objects (circle, ellipse, arcs, splines, etc)...this will ultimately start putting a lot of stress on your processor. Autodesk devised to degrade the representation of these objects to alleviate overhead processing & improve performance. Therefor, a simple circle might look like a hexagon.
To increase the resolution, type 'options'. Under the 'Display' tab, adjust the number under 'Arc and circle smoothness'. Yours is probably set at '1'. The default is normally '1,000'
Let me know if this helps!
