Wow, thanks guys. I'm now on the right track to have crisp, quality images devoid of jaggy lines. Yay!

What is the best way to prevent 'jaggy' profile lines when exporting SketchUp images into Photoshop or another graphic design software?

I ask because most of the presentation-quality exported SketchUp images I've seen around the Internet lack those jaggy lines. Regardless of the size, the images remain sharp, and that is the quality I'm trying to achieve.

Any help would be appreciated.
