Curved 3d form not smoothing

Posting this in the main forum, since, like a noob, I might have posted the original in the wrong location.

I've been having an odd problem in 2008 with some curved solids I created in a 3d model. The forms seem fine when I hide them in a non-perspective view (elevation/axon), but the moment I'm in a perspective view (saved camera) all of the curved forms become blocky and faceted. This also happens when I try to render these views as well. I've kind of narrowed it down to something in the 3dwireframe/hidden views versus 2d wireframe, but I'm having no joy at resolving this.

Any suggestions?

I've adjusted all of those settings, this is something different. It's something specific to a perspective view, but I've never encountered it before. Here's a screen shot showing an Axo and Perp view which illustrates the problem.

Cool model.. It looks huge.
Never seen that problem before, can i ask how far the problem point is from 0,0,0? Have you tried changing the UCS to that point to eliminate the possibility of distance being the cause?

I've seen this behavior when adjusting the dview using zoom and distance to
get a wanted perspective. This is usually display related.
