# PiProbe — OCCT molecule-mode

PiProbe molecule produced by the new OCCT `service-occt` molecule-mode pipeline
(`/convert?molecule=true`): STEP exported from KiCad 10 (with the Adom
`existing-v2.1` 3D library) → OCCT STEP→GLB → **auto-anchor** (front-left machine
pin → origin, up-axis auto-detected) → **gold PBR** on pins/contacts → **join +
Draco**. End-to-end pipeline validation artifact (anchor verified: FL=MP2, up=Z).
