Autodesk has been reorganizing their website. While looking around I recently saw a NEW topic within the HOW-TO section. It is called Skills Builder.
Within this section Autodesk will provide Intermediate to Advanced training on specific segments of Civil 3D.
The first set available is for learning about Superelevations. There is a PDF (the exercise) and the dataset necessary to learn the topic.
To find Skill Builders click on the title of this post or find Skill Builders in the left column of this blog.
Note: I believe that I now have to fix a couple of links in the left column. If you should find any please drop me a note.
