Wassim Jabi has published an introduction to TGraph, describing it as a more explicit and efficient graph representation for TopologicPy.
TopologicPy is an open source Python library for spatial modelling and analysis in architecture, engineering, and construction. Its graph-based representation is used to connect geometry, topology, information, graph databases, knowledge graphs, GraphRAG workflows, and graph machine learning. A clearer graph layer is therefore relevant for workflows that need to reason about spaces, adjacency, connectivity, and semantic relationships rather than only geometric shape.
For OSArch readers, the announcement is another sign of TopologicPy’s focus on BIM-adjacent spatial intelligence: lightweight topological models, graph analysis, and data structures that can support design exploration, simulation, and AI-oriented workflows while remaining available as free software.
