I am using Creo Parametric 2.0 F000Other than the help center, are there any other documents, such as PDFs, that show the basic operation and creation process?
There is the learning connector: PTC Creo Video Tutorials
Live classes at PTC University: https://www.ptc.com/en/ptc-university
Student How to Model Anything PDFs: http://apps.ptc.com/schools/How_to_model_almost_anything.zip
Try Amazon.com for some books on Creo.
Creo 2 is about 8 years old, so not much available anymore.
