A RAG agent shows evidence directly on construction drawings

A Reddit user shared a GraphRAG agent used with construction drawings. Instead of footnote-style citations, it highlights entities from the answer on the actual drawings and replays the path across sheets. The user asks whether this kind of visual evidence really builds trust, or only feels useful at first.

Key points

  • The example is about construction drawings, where a wrong answer can be risky.
  • The agent shows evidence visually instead of only using footnote-style citations.
  • It highlights entities named in the answer on the real drawings.
  • It replays the relation path from member to spec to governing doc.
  • The post asks what users actually check before trusting a grounded RAG answer.
