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:

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