It is my current understanding that an update exists for SolidWorks 2003 in the form of Service Pack 5 or probably just call it SP5. I went to the SolidWorks websitte and it appears that they want you to pay some fee and join up in order to get product updtates. And who knows, they might even ask me a stupid question like, "So what dealer did you get our software from exactly?".
So if anybody knows of a better place to download these updates please let me know.
