In older versions of the software, there used to be a background batching process that ran to automatically nest liner based on the scanning of barcodes.
Essentially you could scan the code for a pieces you were wanting to cut the liner for, which would then send them back to be batch nested in CAMduct. You could then cut the liner with the metal it would be going with, rather than the current state of having metal and liner nested in separate processes without any ability to sort based on the actual item order.
Essentially this is a type of on-demand nesting capability. You could scan the labels, it would create a file that was sent back into CAMduct that you could then batch process, allowing for more organization of metal and liner parts.
