If you are working in Civil 3D 2008 and you open a drawing from an earlier version, sometimes your assemblies look a little funny.
A regen doesn’t fix it… what does?
There may be other ways to snap this assembly back into reality, but I find that all it takes is right-clicking the assembly, going into assembly properties, switchingÂ to the construction tabÂ and then. leaving assembly properties.
It also seems that a quick convert to .NET does the trick, too.
