For 2006 it's on CD2 in the CIVTUTORIAL.CAB under BIN/INSTALLER
For 2007, I don't have the DVD but it should be under:
BIN\INSTALLER\PROGRAM FILES\ROOT\HELP\CIVIL 3D TUTORIALS\DRAWINGS

Where on the installation disks can I find the tutorial drwings? I want to
reopen the surface-1.dwg in its original state.
