In this post I want to show you that exchanging data between Civil 3D and Carlson Survey is relatively easy. I made two posts today about transferring data using LandXML. Additionally, in this blog post at Carlson Connection you will find that working with Civil 3D data in Carlson/IntelliCAD is not such an impossible chore. Carlson Survey for example has a command to convert a Civil 3D or Land Desktop surface to a Carlson TIN file.
