Faceted looking extrusions

What is going on here? I’ve seen this problem before, but I don’t know what causes it. Solid extrusions seem faceted and angular, rather than smooth. Is this just some kind of resolution setting?

Thanks for your help!

Hi Josh- check the setting(s) in DocumentProperties > Mesh. More info here: http://wiki.mcneel.com/rhino/meshfaq
