01
Geometric data
Volume (cm³), surface (mm²), bounding box (X, Y, Z in mm), centre of mass — calculated directly from the geometry.
Microservices · STEP Reader
STEP files read in seconds.
The STEP Reader analyses STEP files automatically, returns volume, surface, bounding box, classifies the machining technology and extracts hole features — structured as JSON, integrated straight into your workflow via REST API.
What the STEP Reader returns
The geometric data you need — structured.
Every STEP file is processed in under 5 seconds — whether it's a turned, milled or sheet-metal part.
02
Technology classification
Automatic recognition: turned part, milled part or sheet-metal part. Basis for routing in production planning and cost quoting.
03
Holes
Number of holes, diameter distribution, depths. Distinguishes blind holes from through holes.
04
Material density approach
With the material density provided, part weight is calculated directly — basis for material cost and shipping weight.

Typical use cases
What companies use the STEP Reader for.
A
Quoting
Inbound CAD requests are auto-classified (turning, milling, sheet) and passed with volume + bounding box to the quoting tool. The manual first-pass review goes away.
B
Webshop configurator
Customer uploads a STEP — STEP Reader returns geometry in seconds — webshop shows instant pricing. No human in the loop, 24/7.
C
Material planning
Volume × material density = part weight. Direct input for material ordering and stock planning — no more reading every STEP file by hand.
Test the STEP Reader in your own toolchain.
30-minute demo call — we run the STEP Reader on your own STEP file and talk through volume, sandbox access and integration.
