Microservices · PDF Reader

Technical drawings read automatically.

The PDF Reader captures dimensions, tolerances, threads, materials, surface treatments and GD&T symbols directly from PDF drawings. Structured JSON output, ready to use in quoting, work prep and ERP.

What the PDF Reader returns

All relevant drawing data — structured.

Everything that would normally be retyped by hand now arrives as a structured API response.

Dimensions & tolerances

Nominal dimensions, general and individual tolerances, ISO classes, fits (e.g. H7/g6). Recognises hand-written adjustments too.

Threads & holes

Thread designations (M6, M10, ISO, UNF), hole types (through, blind, countersink), count and position.

Materials

Material designations (1.4301, S235JR, EN AW-6082, TECAPEEK), DIN numbers, alternative material entries from title block.

Surface treatment

Galvanising, anodising, powder coating, blackening, painting — including specifications (coat thickness, RAL colours).

GD&T symbols

Form and position tolerances per ISO 1101: flatness, parallelism, perpendicularity, position, runout — with values and datum references.

Title block

Drawing number, revision, scale, date, author, general tolerances (ISO 2768-mK). Standardised output.

API example

One request, complete drawing data.

Typical use cases

What companies use the PDF Reader for.

Quoting

Inbound PDF drawings are read automatically. Material + surface treatment + tolerances arrive structured into the quote — 10-15 minutes saved per request.

Work preparation

Your work prep team gets dimensions and tolerances pre-filled — they verify, refine and release instead of retyping every drawing by hand.

ERP master data

New incoming articles are auto-created in the ERP with material, tolerance class and surface treatment — no manual transfer from the PDF.

See the PDF Reader on your own drawing.

30-minute demo call — you show us a typical PDF drawing, we run the PDF Reader live and discuss integration and volume.
