Integrate AI-powered construction drawing recognition into your applications via REST API. Extract structured data from CAD drawings, PDF construction documents, and scanned images—including text, symbols, dimensions, and annotations that standard OCR cannot parse.
Skip the ML training and custom OCR logic. Integrate production-ready AI drawing extraction in days, not months.
CAD exports, PDF construction documents, scanned as-builts—send any drawing format and receive consistent structured output every time.
Process thousands of construction drawings per hour. The API handles load, caching, and sheet management so you can focus on features.
Building software that understands construction drawings is incredibly complex. Traditional OCR fails on technical drawings—it cannot read drawing symbols, decode dimension strings, or understand the relationships between callouts and geometry. Training custom ML models requires massive datasets and specialized expertise. Teams waste months building fragile parsing logic that breaks with every new drawing format, format variant, or legacy scan.
The Nomic Drawing Parse API gives developers instant access to production-ready AI OCR and extraction for construction drawings. Send any drawing—CAD export, PDF construction document, or scanned as-built—and receive structured JSON with extracted text, symbols, dimensions, annotations, and geometric relationships. No ML expertise required. Just a few lines of code to unlock drawing intelligence that already understands AEC drawing conventions, symbol sets, and sheet structures across millions of construction drawings.
Integrate construction drawing parsing in minutes, not months. The REST API accepts CAD-derived PDFs, scanned as-builts, and image files and returns clean, structured JSON. Well-documented endpoints, SDKs for major languages, and predictable response schemas let you focus on building features—not fighting with drawing formats or training OCR models.
Process entire construction drawing sets in a single API call. The API maintains sheet relationships, understands revision history, and preserves cross-references between plans, details, schedules, and elevations. Query individual sheets or complete packages—pagination, caching, and sheet ordering are handled automatically.
Answers to common questions about this workflow.
Yes. The Nomic Drawing Parse API accepts PDF construction documents, CAD-derived PDFs, and scanned drawing packages. It returns structured JSON with extracted text, symbols, dimensions, annotations, and sheet metadata—content that standard OCR tools cannot parse from technical drawings.
Standard OCR reads printed text but cannot interpret construction drawing symbols, callout relationships, dimension strings, or sheet structure. The Nomic API uses AI trained on AEC drawing conventions to extract symbols, annotations, geometric content, and cross-sheet references as structured, connected data.
Yes. The Drawing Parse API handles scanned as-built drawings, hand-annotated PDFs, and legacy drawing formats. The AI reads drawing content rather than relying on machine-readable text layers, so it extracts meaningful data from scanned construction documents.
The API accepts CAD-exported PDFs, native PDF construction documents, scanned image files (JPEG, PNG, TIFF), and multi-sheet drawing packages. Output is structured JSON with drawing content, sheet references, and extracted annotations.
