Did you already check http://learningconnector.ptc.com for free tutorials?
If you cannot find one, it might be a good idea to post this question in the product area of this forum, so your peers can see it and offer help.
If you are interested in formal training, I can offer you to get in touch with a local training advisor. You can contact them through this form >>
Hope this helps!
