Duct Creation Error

Thanks @Robert_Younger for that explanation. This was much more simpler then what I was making it be. Silly mistake on my part. Thank you for helping… Re-writing the “All Elements of Type output” sends Element type (ID: 53391) just fine.

The python script gives another error message that I’m not too sure about. Do you know what it means? Does it have anything to do with the list for the diameters?

Thanks Robert,
