Ah, it sounds like what you were using is rasterizing the DWG, even though PDF supports vector natively. To be honest, I can't remember what I used, and it was a really lousy demo version of a lousy Windows app that probably cost about $20-30. I'll see if I can find it again after I eat some lunch, but no promises. It wasn't a good solution, but it worked in a pinch. If I may ask, what is it that you need to view on the N900?
