All factory buildings use manufacturing lines to produce commodities. Factory buildings have one manufacturing line per level, each manufacturing line being able to produce its own product and independently.
The manufacturing lines of a building can be configured using the "City" window (default
F10). It is also possible to configure the manufacturing lines of new buildings at the time of placement, using the options at the bottom of the construction window.
Each manufacturing line has a number of options to control what and how it should work.
The dropdown allows the selection of what commodity the manufacturing line should produce.
The rate at which a citizen runs the job depends on the income tax of the empire, and the ratio of productive citizens versus the number of jobs in the city.
Only when this option is checked does the manufacturing line act as a job in the city, so it is possibly to uncheck unneeded manufacturing lines in order to not waste productive citizens. For more information about jobs usage numbers, see jobs utilization.
Establishes the minimum TL of commodities used in the manufacturing process. Commodities of lower TL than the selected minimum will be ignored when fetching needed commodities for the manufacturing line.
The TL of tools and environmental factors does not matter, since they have no baring on the TL of the end product.
This option does not affect manufacturing processes that don't consume commodities. For example mining processes at mines, farming at a farm, or refining gasses from the atmosphere at a refinery. It also does not affect research.
Components and Tools
The first box lists all the commodities that will be consumed when the manufacturing line is run. The second box list all the tools or other factors that are required, speedup or increase yield of the run. Tools may take durability damage when used.
Fetch and Run
Fetch will take needed commodities from the city's inventory and store them in the manufacturing line. Tools are not fetched, they are first used when the manufacturing line is run.
Run will first attemt to fetch any missing commodities, meaning that using the "Fetch" button is not actually nessasary. If all needed commodities are in the manufacturing line, a check is then made for required tools and environmental factors, on success the process is started.
