This mod allows users to build zone objects that tell the settlers what type of buildings to create. That is where the mod called Sim Settlements comes in.
The problem is for as much time as one can spend building a settlement, the stock building mechanics in the game are not exactly the smoothest, flexible or as rewarding as it could be. As anyone who has played Fallout 4 knows, building settlements can be as much fun as going around and shooting people in the Wastelands of Boston.
