My apologies. The original presenter became ill and could not attend AU, so William Tucker offered to teach the class with little notice. I didn't realize he didn't cover that topic. Other than the latest Help files for Fabrication CAMduct, there is no other information published that I am aware of.

I'm not sure where you are geographical, so I will offer two consultants who can help you. Both are very good.

David Dykes is in England. He was, until a few months ago, the primary product support tech at Autodesk for Fabrication CAMduct. He now has his own consultancy. He's, by far, your best choice. https://uk.linkedin.com/in/david-dykes-6979815b

Garrett Tice is also available and resides in the USA. https://www.linkedin.com/in/garrett-tice-6a928b72
