You may want to take a closer look at the links in the left hand column of this blog. There are many NEW links that you may find useful.
Like what? You may ask. Well, all three survey link tools (Leica X-change, Trimble Link, and Carlson Connect), which will transfer point data between those manufacturer's instruments and Civil 3D are available. Also added were links to the free Civil 3D Webcasts DVD and CD, and more.
I hope this helps.
