This conversation heated up after I made a post to a thread on an Autodesk Discussion Group. Since then we’ve started a valuable conversation about the strengths and weaknesses of both programs.
My response and the original discussion group thread can be found here: Carlson Vs 3D
James’ post is here: View from the Other Side: Why I Chose Carlson Over Civil 3D
Keep watching this space for updates. I’m interested to see what James’ readers have to say and will respond in a week or so.
Update 9/12/2009: I’ve posted my response to the comments from both www.civil3d.com and the Autodesk Discussion Group here: Carlson VS Civil 3D – Revisited
