Bill,

That is three days to learn one small aspect of your software!
.........Three days of C3D Essentials covers everything .......

This is where I think you are mistaken. In-depth training can also be found for Civil 3D. For example, the company that provided our training offers a 1 day class on intersection design (this is not the only in-depth class they offer). Furthermore, 3 days of essentials is equivalent to performing the tutorials supplied with the software, with the exception of being coached along and being able to ask questions. Also time spent answering questions is limited in order for the instructor to cover all of the exercises. IMHO, trying to cover all of C3D's capabilities in 3 days and expect the user to walk away knowing how use it when he gets back to the office is completely unrealistic. I'm not saying the training is not warranted only that it is what it is "essentials".
