AutoCAD Civil 3D 2009 is out in the market and igniting fancies among the civil community. New Civil 3D has added tools for sustainable design, a trend which has taken off in recent time.
Criteria based design for alignment & profile will help roads/highways engineers to check their design in the beginning itself. Surface simplification will enable efficient use of large surfaces without sacrificing data accuracy. Generalization of target to one or more feature lines, survey figures or polylines in Corridor modeling is JUST COOOOL. There are many more powerful features which are waiting to be exploited by you. Have a glimpse of some of the features at http://download.autodesk.com/us/interactiveoverviews/demo/civil3d2009_nfw/index.html
In next post I will be taking topic on Hydraulics & Hydrology (or vice versa, I don't know). Just be aware of the fact that there will be three new extensions available with the release of Civil 3D 2009. These extensions are Hydraflow Storm Sewers, Hydraflow Hydrographs and Hydraflow Express. These extensions offer numerous H&H capabilities.
I expect you will be loving new AutoCAD Civil 3D 2009.
