Symbol Recognition AI
AI that identifies and classifies symbols in construction drawings.
Definition
Symbol Recognition AI identifies and classifies the various symbols used in construction drawings including electrical, plumbing, HVAC, and architectural symbols. These systems can build symbol libraries, count symbol occurrences, and verify symbols match legend definitions. Symbol recognition enables automated drawing analysis.
In Depth
Symbol recognition for construction drawings identifies the graphic symbols that carry meaning beyond their visual appearance — door swing symbols, electrical device symbols, plumbing fixture symbols, fire protection device symbols, and annotation symbols like section cuts and detail callouts. AI classifies each recognized symbol, connects it to the project's symbol legend, and makes the symbol data available for downstream analysis.
Examples
Identifying electrical symbols on power plans
Counting plumbing fixtures
Matching symbols to legend definitions
