Creating a DEM with Civil 3D

imageOne of my users called me the other day asking if there was any way to convert our DTM surface into a DEM surface, as a client had called them asking if it was possible.  The short answer to the question was yes, but let me review the fundamental differences in these formats before getting into the how-to of this task.  Both formats exist for the same fundamental reason – to capture a representation of the earth’s surface.  What differs is the way each stores that data.

Mastering Civil 3D Review

Mastering Civil 3D 2008 Over the last several months I have been working my way through the ever popular Mastering AutoCAD Civil 3D 2008 book, written by the gang over at Civil3D.com (Engineered Efficiency). As a fellow member of the blogosphere, I have had the privilege to establish a professional relationship with a good portion of the Engineered Efficiency (EE) team. For those unfamiliar with EE, they are arguably the best Civil 3D implementation team in the business!

I’ll never forget last spring when I went to the Experience the Possibilities Tour in Washington DC. During the presentation I asked a question about Civil 3D that was in fact both rather detailed, and quirky. The Autodesk representative answered the question, but with some loose ends remaining. After the session broke, Dana Probert of EE (who I had never met in person), found me in the crowd to both answer and explain the details about the feature I was questioning.

My point in sharing that story is that the EE team has many years of experience solving the real-world problems firms implementing Civil 3D. More importantly they simply know how things interconnect within Civil 3D, and can easily recommend the best approach to a given situation. To that end, the book has been structured in way such that you are learning best practices as you go. Taking that one step further for many of the complex concepts, the Mastering AutoCAD Civil 3D 2008 book expands on the why and how of many details.
