software

hello to all,

I am currently a college student looking to enter engineering. I am in
search for cad/cam software with 3-d modeling. I really like pro-e but for
their 200$ student addition, I might be better off spending 500$ total for
an all in one package?

my questions

1st: Is there an all in one package of cad/cam, 3d modeling under $500 with
or without a student discount?

2nd: Is there software which includes all of #1 and capable of lathe, and
mill with 3-4+axis of control?

3rd: Including specs in #2 could it be purchased to work on MAC as well as
IBM compatible??

Thank-you for your time and interest.

Andrew
