@jauntywunderkind420 BIM stands for "Building Information Modeling". It is a set of international digital standards on how to assign metadata and relationships to 3D geometry to describe a building. E.g. a cuboid shape may be called a "wall" and belong in a building "Foo".
Nowadays, for the vast majority of medium to large architecture / engineering / infrastructure construction projects, it is a requirement to organise 3D models with this BIM data to aid collaboration between the many players.

really glad I asked that's super good to know.
just one mild take, would love to see game worlds/virtual space start to be modelled with BIM pieces. as in the real so too for the virtual.
Server run by the main developers of the project 
It is not focused on any particular niche interest - everyone is welcome as long as you follow our code of conduct!
