I'm using civil 3d 2008, with no svc pack or hotfix updates to date.
i am getting the following error message in the sections: compute mat'ls dbox,
"not all of named surfaces or corridor shapes have been mapped to an object in the drawing.
some mat'l quantities will not be calculated."
my earthworks criteria are matched, but the corridor shape, structures: subbase, base, pave1, pave2,
have no object name in the drop down box?
