Hello moyesboy. >formally know as alibrerocks here in the full AD now. You most likely are correct but I have used for a short while another 3D cad package that was about the same price as AD and it was not nearly as good. So it does count on what you come from on how you feel about Alibre.
I vote AD as #1 for it's price range. If you want or need more then you must pay a lot more. But if you don't need the extras then alibre rocks.
