Feature Line from Alignment

In Civil 3D 2010 you can create a feature line from an Alignment and Profile. There is an option on the home tab for feature lines. 

You have the option to either create a dynamic link or have it be static. Once we have the feature line we can project it back to a profile view to check to make sure Civil 3D has done the link correctly or make elevation changes to the static feature line. The benefit of projecting back to the feature line is that you don’t have to create a quick profile and you get to visually change the elevations of the feature line.
