Thanks a lot! SKP Magicians : )

Yes Andriy, but the problem is still visible and when you render you will know what Im talking about. There are these unwanted reflection. So the question is, what to do with this unwanted reflections?

I saved this in version 7. I hope you guys find the way to solve this problem.

First, thanks for the reply.
Dukejazz, I was playing with all possible plugins for smooth and the problem does not disappear; in attachments you can find two screens, one from the top view and one with unsmoothed edges.
Alan, it requires all these diagonals due to the fact that shape of this is quite unusual (see at top view), and I am not able to erase it.
Whats more, I've tried to do it with super precision, I divided circle to max segments, but the problem still exists.

Thanks in advance!

Hello guys,
I have really big problem with aplying material to shape that I made with some extrude plugins. When I select the whole model there appears triangular hidden faces which cause problem to material. I have no idea how to solve this, and so far I didn't find any other way to do my model. Perhaps, there are some plugins? In case that upload attachment didn't work I upload 2 photos on speedyshare.
