Based on my experience, recommend that you do not use AutoCAD Civil 3x for survey computations. I use AutoCAD 2004 for survey computations then export to Civil 2012 for the techs to design the projects.
AutoCAD 2004...? By itself? Without even Land Desktop?
I couldn't imagine doing that. There's virtually no Survey support in AutoCAD 2004. Even compared to Land Desktop, we can do far more work, far faster, and to higher quality levels with Civil 3D. There are things that would take us days with LDD, and we do them in hours now. One trained C3D tech can keep up with three or four field crews, easy. We used to have more of a 1:1 relationship between field and office staff when we used LDD.
I couldn't imagine using plain Autocad, especially something as old as 2004... We use too many of the new features too much. The Sheet Set Manager alone saves an incredible amount of time. Not to mention MLeaders, Annotative Text, 3D Visualization styles like "Shades of Gray", and more. I'm not a fan of the yearly release cycle and the new crop of bugs that comes with each new release, but I would be miserable using AutoCAD 2004 again. And I don't think I could use LDD at all at this point, not even LDD 2009...
