What version are you on? We do have lots of free tutorials on the PTC Learning Connector platform - take a look: PTC Learning Connector
It contains free tutorials, and lots of other content. If you have access to eLearning (which is now available with every Creo subscription), you can also access full eLearning courses through this portal.
If you have specific training needs, you can also speak to a training advisor in your area. Just fill out this form and we will call you back!
