I don't know if your camera is set up properly. When Bryce opens have the default camera set as directors. Also for some reason the camera is set at a 135 degree angle compared to any objects you create. This makes orientation very hard when building scenes. Anyway if thats the case have a look at this. Also there is some very good tutorials on there to try.

As a pointer do as many tutorials as possible doesn't matter if they not related to the scene you want to build. It will help you learn more features and help you get orientated.
