OK. I've noticed another apparent bug in Civil3D 2012.
I have a template with nothing in it. I've deleted as many styles as it lets me. One layer (0). Text, dimstyle, mleaderstyle, etc. is all Standard. Basically, this drawing is as empty as I can make it.
When I create a new drawing using this template in C3D 2011, no problems.
When I create a new drawing using this template in C3D 2012, ....
Where did this come from? I have a linetype DASHED2 that appears, and I cannot purge it. I cannot seem to locate it anywhere. It doesn't appear in any normal style, and I can't find it in any C3D standard style.
So, where did it come from, and how can I get rid of it?
