Dear Kevin,
Thank you for your query.
I looked at the main web page describing the BIM Interoperability Tools and see the Enhanced DWG Exporter you mentioned:
- https://www.autodesk.com/solutions/bim/hub/bim-interoperability
- http://www.biminteroperabilitytools.com/dwgexporter.php
I am not aware of any API for driving this, nor would I assume that one currently exists.
However, I am checking with the development team for you to make sure.
Best regards,
Jeremy
