Import GIS data into Civil 3D
Do you have the need to import GIS data, typically ESRI SHP files*, into Civil 3D? Are you still doing it the old way with map queries? Take a look at this tutorial over at Civil 3D for Beginners titled Quick and Dirty GIS Surface Import.
It explains how to import an ESRI SHP file directly into Civil 3D as a Surface. This will save you a lot of time compared to the old method. Even though the article mentions version 2012, it also works in version 2011.
There are actually quite a few good articles to explore while you are over there. Have fun.
*Otherwise known as shape files, but not to be confused with AutoCAD shape files that are typically used in linetypes.
