I have had it for a while so I don't even remember where I got it from but I do know that it is available as a free download on the Internet.
What was I doing for 4 hours? Actually I was following along with the tutorial for Wings3d. The first tutorial showed how to make a "crude" tooth model. The second tutorial is for a doghouse and that is the one that I am working on now.
The above picture may look like an easy object to you but it took me a long time to even get this far - and I'm not even finished with the tutorial yet!
About the hardest thing to do was to make the doors and windows see through - K had a hard time with that one!
As I'm learning the program things are becoming easier to do even though I have a long ways to go - I'm having fun though!
The final render of the doghouse picture was created in Bryce where I simply imported the doghouse model (as it is so far) into Bryce (which I also saved the object in Bryce so that I don't have to keep importing the same 3d object model over and over again).
