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 13 to 30 seconds per sheet, A4 to A1.

Most teams save ~7 minutes per drawing.

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, PNG or JPEG. Multi-page documents (as PDF) 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
