The API for reading engineering drawings

Stop reading
drawings by hand.

Werk24 reads technical drawings like an experienced manufacturing engineer — no training data, no templates. It 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 independent axes

Pick the depth, per drawing.

Three extraction SKUs, mixable in a single call. Ask for only the title block, go deep on geometry, or layer manufacturability insights on top.

01
Axis A · Metadata

Title-block metadata

Drawing ID, designation, material, weight, tolerances, projection, BOM and notes — straight from the title block.

  • drawing_id
  • material
  • weight
  • projection
  • BOM
€0.15 / pg
02
Axis B · Features

Geometry & features

Dimensions, fits, threads, bores, chamfers, GD&T, radii and surface roughness — each with confidence and x/y/bbox coordinates.

  • ⌀ dimensions
  • H7 / G6 fits
  • M-threads
  • GD&T
  • Ra
€0.85 / pg
03
Axis C · Insights

Manufacturability

Primary & secondary processes (DIN 8580), volume and bounding-box estimates, and feasibility signals for quoting.

  • DIN 8580
  • volume est.
  • bbox
  • feasibility

How it works

From PDF to production in hours, not weeks.

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

01

Drop in a drawing

Upload any technical drawing — PDF, TIFF, JP2 or scanned image. Multi-page documents and legacy archives work out of the box.

02

We read every detail

Dimensions, tolerances, GD&T, threads, surfaces and materials — understood in context, across ISO and ASME, at 95%+ accuracy.

03

Land it in your systems

Typed JSON arrives in your ERP or PLM via API, webhook or callback. Need CSV, XML or a custom schema? We return that too.

Extraction depth

More than OCR. It understands technical semantics.

Every field links back to its source in the drawing — so the data is auditable, not just extracted.

  • No training data required — works on the first drawing
  • Confidence & evidence trace per field (x / y / bbox)
  • GD&T understanding across ISO and ASME / ANSI
  • DE · EN · NL · FR · ES · IT · JA
  • REST API, webhooks & a Python client
