    Is there a way to detect if the drawing being opened is from a previous
    release? I would like to put up an alert, or run a script if this is the
    case.

    Thanks

    Read the first 6 bytes of the file, something like this.

    Public Function DwgVersStr(ByVal FileName As String) As String
    VersFile = FreeFile
    Open FileName For Binary As #VersFile
    Chk$ = UCase$(Input$(6, #VersFile))
    Close #VersFile
    Select Case Chk$
    Case "AC1018": Ver$ = "2004"
    Case "AC1015": Ver$ = "2000"
    Case "AC1014": Ver$ = "R14"
    Case "AC1013": Ver$ = "R14"
    Case "AC1012": Ver$ = "R13"
    Case "AC1011": Ver$ = "R13"
    Case "AC1010": Ver$ = "R13"
    Case "AC1009": Ver$ = "R12/R11"
    Case "AC1006": Ver$ = "R10"
    Case "AC1004": Ver$ = "R9"
    Case "AC1003": Ver$ = "2.6"
    Case "AC1002": Ver$ = "2.5"
    Case Else: Ver$ = "Unknown"
    End Select
    DwgVersStr = Ver$
    End Function

    Will this work if trying to detect if a drawing is from MDT or
    Mechanical?
