I am having a hard time writing syntax using this Method (IExportToDWG). Here is the API help page...http://help.solidworks.com/2011/English/api/sldworksapi/SolidWorks.Interop.sldworks~SolidWorks.Interop.sldworks.IPartDoc~IExportToDWG.html
The part that confuses me is the "Alignment" parameter.
Alignment is declared as a Double but, according to the example at the bottom, needs to be a Double().
As a side note...
In ExportToDWG the Alignment parameter is declared as an Object.
