Need HELP with large curve

[komengsky]

I am trying to model a railway tunnel. But I am not happy
with the result because when it comes to large swept boss
feature, it just does not appear to be smooth. You could
see it from the following snapshot.

So is there a way to fix this problem?

Hi ! And well come to the forum.
I think there is no problem with your swept. Except if you need a very good picture.
In SW's mind all is Ok: the circles ARE circles and so on. Is no reason to be worried about.

One thing to try is, to go to the document properties options and under the image quality heading, make sure the slider bars are all the way to the right.
