Topic: insbase not right when

[dugk]

I've written a program to export DXF files from DWG files.  I've used Tony's CaddZone.DatabaseServices.WorkingDatabase code and all seemed to work fine until I found out that the InsBase system variable value of the "db.ReadDwgFile(drawingFile.FullName, FileShare.Read, true, null);" is not what the DWG contains.

The DWG attached has a non-zero based InsBase system variable.  When I step through my code below the db.insbase value is always 0,0,0.

Any ideas/suggestions?

Code: [Select]

try
{
    Database db = new Database(false, true);
    using (CaddZone.DatabaseServices.WorkingDatabase wdb = new CaddZone.DatabaseServices.WorkingDatabase(db))
    {
        FileInfo dwl = new FileInfo(drawingFile.FullName.Substring(0, drawingFile.FullName.Length - 3) + "dwl");
        if (!dwl.Exists)
        {
            db.ReadDwgFile(drawingFile.FullName, FileShare.Read, true, null);
            if (db != HostApplicationServices.WorkingDatabase)
            {
                HostApplicationServices.WorkingDatabase = db;
            }
            db.Insunits = UnitsValue.Undefined;
            db.DxfOut(dxfFolder.ToUpper() + "\\" +
                drawingFile.Name.Substring(0, drawingFile.Name.Length - 4).ToUpper() +
                ".dxf",
                dwgPrecision,
                DwgVersion.AC1800);
        }
    }
}
catch (Autodesk.AutoCAD.Runtime.Exception aex)
{
    if (stringBuilder == null)
        stringBuilder = new StringBuilder();

    if (aex.ErrorStatus == ErrorStatus.FileSharingViolation)
        stringBuilder.AppendFormat("\n{0} is already open!", drawingFile);
    else if (aex.ErrorStatus == ErrorStatus.DwgNeedsRecovery)
        stringBuilder.AppendFormat("\n{0} needs recovery!", drawingFile);
    else if (aex.ErrorStatus == ErrorStatus.BadDwgHeader)
        stringBuilder.AppendFormat("\n{0} has a bad drawing header!", drawingFile);
    else
        stringBuilder.AppendFormat("\n{0} has error {1}", drawingFile, aex.Message);

    continue;

}
catch (System.Exception ex)
{
    acActiveDocEd.WriteMessage("\nError: {0}", ex.Message);
    acActiveDocEd.WriteMessage("\nStack trace: {0}", ex.StackTrace);
    return;
}

Thanks!
