shrug-l: survey data

Good morning, all.

   I have a question regarding CAD data (.dwg and .dxf) files.  When I bring CAD data into a new ArcMap session I get a message that says:

    Unknown spatial reference:

      The following data sources you added are missing spatial reference information.  This data can be drawn in ArcMap but cannot be projected:
                            126.dxf  Group Layer

    However, when I bring another shape file in the session to see if the CAD file is in the correct place, the file is in the correct place.  I have a process which I must follow, (SOP - Standard operation procedure), so this message is one I need to understand so that I can explain it to the surveyor's CAD person.

    Any help or ideas would be greatly appreciated.

Blessings on your day.
