I'm new to Civil 3D. I need to create a large, unregular, paving area, with some defined point location/elevations (paving area is for a mill). I don't know how to create this? Any hint?

I'm going to assume that you already have the outer boundary drawn. Since you've said this is for a pavement milling project, I'm also going to assume that the depth will be the same throughout (so that you're just trying to calc the amount of material you're milling out and putting back).
If that's all true, here's how I would do it.
Now you have a surface representing what it will look like after milling. You can compare this surface to the EG surface to get a volumen calc.
EDIT: Re number 5, here's where you'll find the option to lower the surface. And I'm attaching a sample dwg file in which I've done this for an example. The yellow shape is the outer boundary of the proposed surface.

Thanks very much! I got as far as step no.3. Could you please elaborate on how to achive step no.3? What an EG surface ("Existing Ground" surface?)? Thanks a bunch!
In the toolspace, expand your proposed surface (FG). Take a look at the following screen shot.

P.S. I thought of this after posting that and it might help you understand better.
When you paste one surface into another, the destination surface will look exactly like the one you're pasting except for the changes that happen to it after the paste operation. It's similar to copying the pasted surface but in this case it remains dynamically linked where if you copied it, there would be no link.

I just noticed the second part of your question (in red above). This is just a common abreviation around here.
EG surface = Existing Ground
FG surface = Finish Ground

This is what i call some "expert Elite" support! Thanks for all the details as I'm going to dive into it shortly... Thanks again!
