I downloaded Wings twice and got discouraged each time and unistalled it. Then I found Drac's now classic "simple spaceship tutorial" and followed it step by step and ended up with my first usable model , other than what I had built previously in Bryce. I had so much fun using what I had learned that I ended up modeling for twelve straight hours! I ended up with about a dozen models that I could use, and they weren't half bad.
I've used Wings for a couple of years now and can build a lot of stuff now I would have found difficult, or nearly impossible in Bryce, with the added benefit of being able to export what I built. I built these buildings this weekend while I was on the road with my laptop, which unfortunately has only Bryce4 on it for a renderer.
