OpenDrawing
AI-driven bill of materials creation from electrical single-line diagrams
Computer-vision and OCR platform that reads uploaded electrical single-line diagrams, P&ID schematics, riser diagrams, and panel schedules — including scanned or handwritten legacy drawings — automatically detecting, counting, and labeling components, then mapping them to part numbers to produce a structured, ERP-ready bill of materials. Engineers review every AI-labeled component overlaid on the source diagram and can relabel or remove detections before export. Backed by Techstars (Alabama EnergyTech Accelerator, Fall 2025 cohort).

Why This Tool Exists
Electrical estimating and engineering teams manually extract components from single-line diagrams, P&ID schematics, riser diagrams, and panel schedules to build a bill of materials — a process the vendor states takes 30-60 minutes per diagram — then re-key the results into ERP and procurement systems before parts can be ordered or a job priced.
OpenDrawing uses computer vision and OCR to read uploaded single-line diagrams, P&IDs, riser diagrams, and panel schedules (including scanned or handwritten legacy drawings), automatically detecting and labeling components, counting them, and recommending part numbers based on specifications and standards. Engineers see every AI-labeled component overlaid on the source diagram and can relabel or remove detections before exporting a structured, ERP-ready bill of materials — the vendor states this cuts per-diagram processing to under 5 minutes, for teams processing 100 diagrams/week a claimed 40+ engineering hours saved weekly.
