If it is free, what version,what is the process now. Plus, we are currently using Creo 2.0, are we able to upgrade?
As far as I can see Creo 4.0 is the last one. The update option is currentle available at official website. But if understand properly it's not free.
The PTC Academic website shows Creo 3.0 as the current version for schools and currently still free for teachers and pupils.
