When I save the model as DWG with code, flat pattern turned around 180 degrees. Why? And how to avoid it?

When I save the model as DWG via  File - Save As... , everything is fine.

I save with method ExportToDWG.

My options:

<p>dataAlignment[0] = 1;       //1 to export flat-pattern geometry; 0 to not</p><p>dataAlignment[1] = 0;       //1 to include hidden edges; 0 to not</p><p>dataAlignment[2] = 0;       //1 to export bend lines; 0 to not</p><p>dataAlignment[3] = 0;       //1 to include sketches; 0 to not</p><p>dataAlignment[4] = 0;       //1 to merge coplanar faces; 0 to not</p><p>dataAlignment[5] = 0;       //1 to export library features; 0 to not</p><p>dataAlignment[6] = 0;       //1 to export forming tools; 0 to not</p><p>retVal = swPart.ExportToDWG(newPath,        //FilePath </p><p>                modelName,      //ModelName </p><p>                1,              //Action </p><p>                true,           //ExportToSingleFile </p><p>                null,           //Alignment  </p><p>                false,          //IsXDirFlipped </p><p>                false,          //IsYDirFlipped </p><p>                options,        //SheetMetalOptions </p><p>                null);          //Views </p>
