Thank you epsilon.

But I have still one problem. This model is a part of a fair ride. the arms rotating around the centerpiece. I have attached them, but when it rotates around the centerpiece, the model frooze a couple of frames. I know it's because "wait(1);". But is there a way to run it smoothly?

So, the model (arm) it rotating around the centerpiece (with my.pan) and it's tilting (with the code you gave me).

Thanks in advance.
