Not to bring up an old subject but... Being fairly new at AutoCAD I am using Civil CD 2012 and have this same problem with the "fenceline" linetype. If I forget to reload it before I plot a set of plans then all my silt fence or chain link fence come out to be a dashed line without the circle. Anyone figured out what the issue is? It isn't a big deal to reload the line type but... It shouldn't be something I need to do.
I think it first came up when I created a new line type. Maybe it is reading the wrong .lin file. How can I find out which one it reads when Civil 3D starts and which one it reads when I go to reload the line type.
