Unable to create flat pattern

[JelteDeJong]

Im writing a addon in c#. This addon needs to create a drawing from a part file that is active when i run the addon. It needs to create a view from a flat pattern in a idw.

below you find the relevant code. Most code is copyed from the help file and converted to c#.

Document oDoc = inv.ActiveDocument;// <-- assume this is a part document

string templatePath = inv.FileManager.GetTemplateFile(DocumentTypeEnum.kDrawingDocumentObject);

DrawingDocument oDrawDoc = (DrawingDocument)inv.Documents.Add(DocumentTypeEnum.kDrawingDocumentObject, templatePath);

Sheet oSheet = oDrawDoc.ActiveSheet;

NameValueMap oBaseViewOptions = inv.TransientObjects.CreateNameValueMap();
oBaseViewOptions.Add("SheetMetalFoldedModel", false); // <- if this is set to "true" it will work

TransientGeometry oTG = inv.TransientGeometry;
Point2d insertPoint = oTG.CreatePoint2d(15, 12);
DrawingView oFrontView = oSheet.DrawingViews.AddBaseView(
    (_Document)oDoc, insertPoint, 
    1, 
    ViewOrientationTypeEnum.kCurrentViewOrientation,
    DrawingViewStyleEnum.kHiddenLineDrawingViewStyle, 
    "", 
    null, 
    oBaseViewOptions);

The line "oBaseViewOptions.Add("SheetMetalFoldedModel", false);" is the option that tells inventor to create a flat pattern. This option only fails if i set it to "false". (if i set it to "true" the code runs with out any problems but i dont get a flat pattern.)

the error message is:
System.ArgumentException: The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

Can some one tell me what i should do different?

I found the solution.  the "ViewOrientation" may not be set to "ViewOrientationTypeEnum.kCurrentViewOrientation". It works if i set it to "ViewOrientationTypeEnum.kDefaultViewOrientation"
