Stop Reading Drawings by Hand

Werk24 reads technical drawings like an experienced manufacturing engineer — no training data, no templates. Extracts PMI, GD&T, tolerances, materials and threads into structured JSON for ERP, PLM, MES and quoting tools in under 20 seconds.

Most teams save ~7 minutes per drawing.

Three steps from drawing to structured data

No templates, no training, no manual prep. Upload a drawing and get verified, structured data back in seconds.

  1. 1

    Drop in a drawing

    Upload any technical drawing — PDF, TIFF, or scanned image. Multi-page documents and legacy archives work out of the box.

  2. 2

    We extract every detail

    Dimensions, tolerances, GD&T, threads, surfaces, materials — all understood in context with over 95 % accuracy.

  3. 3

    Get clean data in your systems

    Structured JSON lands in your ERP or PLM via API, webhook, or callback. Need CSV, XML, or a custom schema? We deliver that too.

How it works under the hood

Ingestion

  • Accepts PDF, TIFF, JPEG, JP2, PNG, BMP
  • Multi-page scans and archive copies in scope
  • Integration via HTTPS POST or Python SDK

Extraction & accuracy

  • Interprets metadata and PMI in context — GD&T, threads, surfaces
  • Confidence scores per field
  • Deterministic, typed JSON — maps directly to ERP/PLM schemas

Feasibility analysis

  • Overall dimensions (raw/finished), process info (DIN 8580), volumes
  • Go/no-go flags at RFQ intake
  • Optional webhooks or callbacks for lights-out processing

Delivery

  • JSON, CSV, XML, or custom ERP/PLM schema
  • Webhook and callback delivery
  • Deploy without process changes — low adoption barrier

Data extraction from manufacturing drawings

Werk24 is more than OCR—we understand technical semantics. Each output is normalized, pixel-precise traceable (x/y/bbox), and ready for ERP/PLM/CAD-CAM.

  • No training data required
  • Confidence & Evidence trace per field
  • GD&T understanding (ISO/ASME)
  • API, Webhooks & Python-Client

Title block and metadata extraction

  • Identifiers
  • Materials (normalized)
  • Units
  • Revisions
  • Part List
  • Notes
Recognizes and normalizes drawing numbers, designations, materials, units, weights, revisions, part lists, and notes—including mapping to canonical values.

Geometry, GD&T and feature detection

  • Measures
  • Limits/± tolerances
  • Fits (e.g. H7/G6)
  • GD&T
  • Thread
  • Roughnesses
Linear/angular dimensions, limits/± tolerances, fits, GD&T (reference points, FCF), holes/chamfer/radii, thread identification (metric/imperial) and surfaces-with confidence and coordinates.

Comprehensible evidence for compliance workflows

  • x/y/bbox-anchor
  • Confidence per field
  • Explainable sources
  • Review-ready
Each field links back to its source in the drawing. Ideal for human review, audits, and efficient exception handling.

Normalization and multilingualism

  • ISO AND ASME/ANSI
  • Multilingual
  • Units & dual units
  • GD&T
  • Thread (DIN/ISO/UNC)
We understand ISO and ASME/ANSI drawing styles and analyze notes, typefaces, and GD&T in multiple languages (German, English, Dutch, French, Spanish, Italian, Japanese). Werk24 normalizes units, symbols, projection types, thread systems, and GD&T into a uniform schema.

Drawing automation

Upload a drawing and receive structured JSON—no model training required. Integrates with costing, ERP/PLM, CAD/CAM, or analytics via REST API, webhooks, and Python client. We calibrate on your data for custom rules or quality gates.

Works on day one. Even on drawings from 1987.

Competitors need months of annotation before they recognize your title block. Werk24 ships PMI extraction the moment you connect — across ISO and ASME, German and Japanese, scanned faxes and clean PDFs.

0 training samplesNo templates, no annotation rounds, no model fine-tuning. Connect and extract.
ISO & ASMEBoth standards normalized out of the box — no per-standard configuration needed.
6 languagesGerman, English, Spanish, Dutch, Japanese, Italian — detected and parsed automatically.

Supported drawing formats

Werk24 focuses on mechanical drawings—enabling maximum accuracy, even with scans and legacy archives.

Supported drawings Supported example

  • Component drawings (parts, details)
  • Assembly drawings (mechanics & substructure groups)
  • Scans of sufficient quality (≥ 200 dpi, 300 dpi recommended)
  • Clean, hand-drawn technical drawings (complete dimensions & notes)

Unsupported drawings and files Unsupported example

  • Building and architecture floor plans
  • P&ID assembly schemes or process flow diagrams
  • Electrical or wiring plans
  • CAD-native files (DWG, DXF)—please export as PDF or raster
  • Sketches, whiteboards or incomplete drawings

Werk24's output format matches your system's

Choose between Standard API for quick entry or a Custom Profile that matches your ERP/PLM/MES/QMS requirements—including field names, types, units, and formats.

Why the mapping stays consistent

  • Semantic core: We normalize ASME/ISO styles and languages before formatting to your schema.
  • Traceable: Each field links to evidence for audits and PPAP/FAI.
  • Typed & validated: Units, ranges, and enums are checked before delivery.

FAQ — Automated Processing of Technical Drawings

The most common questions from engineering and operations teams—clearly answered.

Which drawing formats are supported?
Werk24 processes PDF, TIFF, JPEG, JP2, PNG, and BMP—including scanned legacy drawings and multi-page files.
CAD-native formats (DWG, DXF) are not supported, as these require proprietary software licenses. We achieve the highest accuracy by focusing on 2D drawings. View format overview →
How accurate is Werk24?
Our extraction accuracy regularly exceeds 95% with standard annotations and up to 99% with custom quality gates. If information is unclear, Werk24 rejects the drawing instead of guessing—ensuring no incorrect data enters your system.
How do I get the results?
By default, Werk24 delivers clean, structured JSON. We also create custom output formats tailored to your ERP, PLM, MES, or QMS schema. No middleware, no copy & paste—ready to use immediately. View examples →
Are there SDKs and APIs?
Yes. Werk24 is built for developers:
  • Python-SDK on PyPI to get started immediately
  • HTTPS-REST-API with Webhooks for every language
  • Structured endpoints for meta data, features, insights, redactions, balloons and thumbnails
explore the API-documentation →
Where are my data processed?
You decide: EU or USA data residency. All files are encrypted in transit and at rest; storage and deletion are configurable.
How fast is the processing?
Most drawings take 5–20 seconds per page. Provisioned tiers give you guaranteed parallelism (1–3 jobs). Enterprise plans scale as needed. Werk24 runs 24/7—no bottlenecks.
What is the price model?
Three service tiers: Essential (€490/mo), Growth (€1,490/mo) and Corporate (from €2,990/mo) — each with included pages plus per-page processing from €0.15 (Metadata) to €0.95 (Insights). Higher tiers include more pages and volume discounts up to 55%. View full pricing details →
Can I test Werk24?
Is Werk24 available worldwide?
Our core markets are Europe and North America. We support enterprises worldwide under German law. Wherever your business relies on drawings, Werk24 can support you.
Do I need training data?
No. Werk24 works out of the box—no templates or annotations needed. Training data is only required for a custom quality gate targeting up to 99% accuracy on specific features.
Does Werk24 store my drawings?
By default, drawings are deleted after processing. On lower tiers, we may store parts of the drawing for up to 21 days to improve our software. Higher tiers offer a strict zero-retention policy: files are not retained beyond the extraction process.
