Martin, One of our application engineers, Andy Deighton alerted me to your enquiry. Normally commercial Pro/E files cannot be opened in Education versions of the software. Under exceptional circumstances we can convert files. I will make enquiries to see if this is possible with the parametric gear model and get back to you. In the meantime could you let me have your email address and role so I can keep you posted on developments in our education programme? Many thanks Tim -
