We've finally made it available on YouTube. . .the infamous video that explains one procedure on how to import GIS data into Civil 3D. Yes, you read that correctly. . ."one procedure." There are a few others. This is a method that I've been using for years simply because it's simple. The other methods aren't hard, but you need to understand a little bit about Map 3D before you can use them. Remember, I’m not a GIS guru nor do I know where all the GIS websites reside. The data that I’m using here is data that I’m familiar with and was found freely over the web, but most GIS data could be imported and act in a similar manner. I hope you find it informative.
