Need Help- circular glass becoming polygonal

[musyas]

I made a Circular glass, then after rendering it became polygonal shape. Btw i used AutoCAD ver 2007 in rendering. I hope can figure my problem about rendering. So how is this? What properties should I change? give me some guides.. Before anything else, zoom the image

so that you can see the changes of the glass.

Thanks....

type "facetres" in the command, if the value is 0.5 change it to 10 which is the highest, this should fix your problem..check viewres,surftab1, surftab2 as well, increase their size as necessary, check out help for further info.
