The Production Interface, or as it is more commonly known - the Macro-builder, is a button located under the left side of the country crest at the top-left corner of the in-game screen.
The macro-builder contains some of the more commonly used actions in the game, presenting them with relevant color-coded and sortable information allowing for easier decision making. If the shown data is not enough, it is possible to hover over the present data to get a more in-depth tooltip.
The hotkey b opens the macrobuilder, then each of the first 10 tabs can be selected using the numeric keys 1, 2 ... to 0 (not the number pad).
Units are displayed with stats and ducat cost (and for mercenaries, how many are available).
At the bottom are displayed the land force limit, and number of units currently owned and in production per unit type.
Hovering shows the number of regiments owned of that unit type and its maintenance cost.
Choosing a unit will color-code the provinces (green / red according to whether those troops can be raised there) and display ducat cost and time to build. Clicking on a green province will begin construction.
Provinces with unit construction in progress display percentage progress and number of units in the queue.
The section at the bottom details currently defined army templates. (Requires Art of War or Cradle of Civilization.)
Selecting one highlights valid provinces with cost and time, and then clicking on a province begins construction of the template, setting that province as a rally point.
Only contiguous provinces will be used for unit construction, and only up to the limit set by the template.
This tab allows conversion of a province's culture. At the top there is a button to chose culture to convert into (advanced culture conversion requires DLC; without it, only primary culture is available). Selecting a culture will display only the provinces that can be converted into that culture.
Provinces are displayed with current culture color-coded for acceptance (green / yellow / red). Hovering over the culture shows current culture effects on province (from acceptance level).
A gold star indicates primary culture; a silver star, accepted cultures; a bronze star, cultures in the primary culture group.
The next column shows diplomatic power cost or, if already converting, a progress bar.
A button allows starting the conversion process. Hovering over it gives an expanded tooltip icnluding time to convert.
This tab allows construction of buildings in provinces.
Buildings are displayed with ducat cost and upgrade path. Grayed-out buildings are not unlocked as of yet.
Hovering shows effects of building and time to build (also fort maintenance for forts). Grayed-out buildings display required technology to unlock.
Choosing a building will color-code owned and subject provinces:
green: building can be built
yellow stripes: building can't be built because the province is busy (e.g. a missionary)
teal: building can upgrade another building that's already present
blue: building already present
red stripes: not enough money
Choosing a building also displays remaining building slots, ducat cost, and, if relevant, effects on trade power, income, state maintenance, manpower, sailors, force limits, and trade value. Hovering shows time to build and an expanded tooltip.
Provinces in mid-progress display percentage progress.
Provinces are displayed with trade good, monarch power cost, development and local autonomy. There is also a break-down of tax, production and manpower with scaled color-coding (green / yellow / red) based on effects of future development type.
Hovering shows trade good price, the percentage of impact from development and effects of development type (an expanded tooltip as well).
At the bottom are one or two checkboxes:
Include Territories excludes non-state provinces if not ticked.
Include Subjects includes subjects' provinces if ticked. (Requires Rights of Man.)
Estates are displayed with color-coded (green / yellow / red) loyalty, influence and estate territory.
Hovering shows loyalty decay, influence modifiers break-down and a list of estate controlled provinces (an expanded tooltip as well).
Choosing an estate will color-code non-estate provinces with (green / red) stripes. Estate controlled provinces will be colored according to their estate and display the amount of influence they grant to that estate, the province's current autonomy, and the amount of development in each category. Hovering over non-estate provinces shows effects of grant on the estate and estate effects on the province if it's potentially accepted; acceptance modifiers if it's potentially denied and revocation date if it's an estate controlled provinces.
This tab gives an overview of diplomatic actions that are available to the player. This tab has eight subsidiary tabs, corresponding to seven of the categories of diplomatic actions plus improve relations.
Improve Relations: This tab allows you to send diplomats to automatically improve relations with certain categories of country. Diplomats assigned this way will choose a country to improve relations with and carry on until reaching +100 improved relations modifier, then switch to another if possible. If all countries in a category are already at maximum, the diplomat will sit idle. The buttons for any empty categories are greyed out.
Neighbouring Countries are any countries that share a land or sea border.
Own Subject Countries includes tributaries but not trade league members.
Outraged Countries are countries whose opinion of you is impacted by aggressive expansion.
Allies does not include subjects, guaranteed countries, or trade league members.
Threatening Countries includes any country that poses a threat.
The other tabs are Alliance actions, Influence actions, Dynastic actions, Economy actions, Papal actions, Emperor actions, and Great Power actions. Each tab gives a list of possible actions; selecting one gives a list of countries, with / and acceptance numbers if applicable, and ineligible countries greyed out. Clicking a country enters diplomacy with that country with the appropriate option selected.
The following interactions are not available here:
This tab allows the creation of Army / Navy templates for the easy production of units corresponding to the template. The templates can be accessed and created in each of the appropriate tabs; they work in the same manner for both army and naval tabs.
At the top give the template a desired name.
At the middle assign the desired numbers to the types of units and chose a number of provinces to build in simultaneously.
At the bottom are displayed ducat costs, land maintenance / naval maintenance and time to build (also manpower for land units).
Click on the save button when done.
To use a saved template click on it and choose an area to build in (the units will be built simultaneously in the surrounding provinces).
