Deciphering P&IDs: A Neo4j Approach to Design Automation
summary
A Neo4j-based pipeline converts P&ID XML into a graph of about 1 million nodes per project, runs graph algorithms to automate takeoffs, instrument-loop detection and isolation-valve searches, and exposes a drag‑and‑drop UI that generates Cypher pattern matching queries (set hop range, node degree, properties) and returns matches quickly. Tech stack ties the viewer to Neo4j/AuraDB and a React front end, and the roadmap moves from topology integration toward 3D and generative design.
