If you search "coordinates" in the map 3d forum >>here<, there is some code available.  If you still have questions, I suggest you post there.


Here is some vb to get all coordinate systems - there were more than 5,000 systems available when this was done for Map 3D 2011.


Private Sub GetCoordinateSystems(ByRef systemcounter As Integer)
        Dim msg As String = "GetCoordinateSystems" & vbCrLf
        Dim csyssysfac As New MgCoordinateSystemFactory()
        Dim csyssyscat As MgCoordinateSystemCatalog = csyssysfac.GetCatalog()
        Dim csyssysdic As MgCoordinateSystemDictionary = csyssyscat.GetCoordinateSystemDictionary()
        Dim csysenum As MgCoordinateSystemEnum = csyssysdic.GetEnum()
        Dim csyscount As Integer = csyssysdic.GetSize()
        Dim csysnames As MgStringCollection = csysenum.NextName(csyscount)
        Dim csysname As String = Nothing
        Dim csys As MgCoordinateSystem = Nothing
        Dim csystype As Integer = 0
        systemcounter = 0
        For i As Integer = 0 To csyscount - 1
            csysname = csysnames.GetItem(i)
            csys = csyssysdic.GetCoordinateSystem(csysname)
            csystype = csys.GetType()
            systemcounter += 1
        msg = msg & "systems counted " & systemcounter
    End Sub 'getcoordinatesystems
