To build a room adjacency graph, convert Sverchok building geometry into a CellComplexByFaces topology, then use GraphByTopology to generate a dual graph where rooms become vertices and shared walls become edges for routing and circulation analysis.

Mesh-based topology analysis fails for non-manifold AEC workflows because it cannot correctly reason about shared boundaries and space connectivity, whereas TopologicSverchok CellComplex structures explicitly handle room connectivity and envelope metrics.

To separate external envelope faces from internal walls, construct a CellComplex from your geometry and use CellComplexDecompose to decompose the structure, preventing common envelope overcounting mistakes during energy simulation preparation.

Yes, TopologicSverchok requires planar face inputs and correct tolerance handling to properly convert Blender geometry into Topologic topology objects for reliable CellComplex construction and adjacency analysis.

Yes, you can use IFC-to-topology workflows in Blender BIM by importing building space geometry into Sverchok, converting it via TopologyByGeometry, and generating CellComplex structures for space adjacency and dual graph analysis.

The best way to prepare building topology for energy simulation is constructing a CellComplex and decomposing it into external versus internal faces to calculate accurate envelope areas without overcounting shared boundaries.
