I have recieved a .stp file from a company we are working with on a project.  It was originally made in catia, it is almost half a gig!!  My computer doesnt have enough horsepower to open it.  It says " parsing file, pass1" then says not enough memory.  Ive rebooted, not opened anything else, increased my page file size.  Still cant open it.  Does anyone know of anyway that I can open this, or convert it and make the data usable...........other than buy a better comp?  What size / kind of computer do you need to deal with files of such size?  Thanks.
