Hello!  
Are there examples of how building creation works in game mode. We have a plane divided into squares, in each square you can build buildings, like a Sims city or Warcraft 3. we have a grid.

How can you implement this on Three.js?

There is an official example from the repository that demonstrates a simple voxel editor. You should be able to use parts of the code in order the implement the positioning of game entities onto the plane.
