Drawing Intelligence
AI that understands the meaning and relationships within construction drawings.
Definition
Drawing Intelligence refers to AI systems that go beyond simple OCR to truly understand construction drawings. These systems recognize that a dimension line connects to specific elements, that a keynote references a specification section, and that drawing details relate to larger plan views. This semantic understanding enables intelligent search, automated review, and cross-referencing capabilities that treat drawings as interconnected information systems rather than just images.
In Depth
Drawing Intelligence refers to the AI's ability to not just read text on a drawing, but to understand the drawing as a designer or engineer would — recognizing spatial relationships, understanding what symbols mean, connecting callouts to their references, and interpreting the intent behind graphic conventions.
Consider a floor plan. A human reviewer sees a room, understands that the thick lines are walls, recognizes the door swing symbols, reads the room name and number, notes the keynotes referencing the finish schedule, and follows a section cut symbol to find the corresponding section drawing. Drawing Intelligence replicates this chain of understanding so the AI can answer questions like "what is the floor finish in Room 203?" by tracing through the floor plan, finding the finish keynote, looking up the finish schedule, and returning the answer.
This matters because most construction questions span multiple drawings. A question about fire-rating does not live on a single sheet — it involves the floor plan (rated wall locations), the wall types schedule, the door schedule (rated frames and hardware), and the details (rated assembly construction). Drawing Intelligence is what allows AI to connect information across sheets and disciplines the way an experienced reviewer would.
