Analysis by object name:Walls are bearing floors, colums are bearingbeams, etc.


Construction algorithmsConstruction algorithms

Analysis by object elevation:Object with a lower elevation is bearing an object with a higher elevation



Analysis by directed graph:Each object is a node in a connection graph.



Analysis by object adjacency:Each object is a node in a topological graph
