damn 70 bucks where did you get it? i have autocad 2004 i use at work and i have had it for over a year and i still don't know 80% of the functions on here. when it comes to 3d modeling pro engineer is the best software i have seen, they pay really good if you know how to use it. it is a more mechanical based software almost impossible to get on the personal market i only saw one person with it outside of a company. what r u trying to draw?
