Well, as of now, it looks as though I will be giving a Civil 3D 2006 class at Autodesk University this November/December. The class will be about Cul-de-Sacs and Knuckles.
I am currenly submitting to give a couple of Civil 3D 2006 classes at a future AUGI Cad Camp. I'll keep you posted.
We here at KETIV Technologies have seen the requests for training on Civil 3D really begin to take off. AU and Cad Camp are a couple of ways to reach more users.
