I know that to transport a PDC I need to prefab it and then rebuild it on site. But on the industry section do each number to build count as an entire PDC or is that how many sections I am building? To clarify I have a PDC that can be assembled in 13 sections. In the industry tab I select the prefab PDC drop down and decide to build 10 items, is that 10 PDC's or have I still to build another 3 items to have 1 PDC?
