Convert Face to Sheet Metal

I'm trying to use the InsertConvertToSheetMetal2 command to convert a face to a sheet metal part.

If I select the face first using ModelDoc2.Extension.SelectByID2, this works fine.

I would prefer to use the Select method of the face directly though (so that I don't have to use the select location in SelectByID2), but when I do this no sheet metal parts are created.

Alternatively, I could use the SelectByID2 method if I could get it to work for a face using the face name.  I can't figure this out however, when I select by name no sheet metal parts are created.

Can someone explain what's happening here?  Or explain how to convert a Face2 object to sheetmetal without having to select it by location?

Thanks a lot
