TRAFFIC INDUSTRIES — TI-C1-PVC75-PARAM-P01

DEV01 nominal design reference, manufacturing tolerances/material/ground-specific fixings not established.

The source variant is 75 cm nominal height, equal to 750 mm. The package contains the 75 cm single cone (4 physical solids) and the source nested-pair arrangement (8 solids; total source assembly envelope 862 mm). The existing site PDF covers 75/90 cm; this package has no 90 cm / 900 mm CAD source or model. No geometry was scaled or invented.

Formats: native FCStd and exact source STEP in mm; IFC4 declared mm; GLB metres; STL has no intrinsic unit and should be imported as mm; DXF/DWG modelspace 1:1 mm. The DXF is copied byte-for-byte from the native 2D source. See source-reference.json and native-occurrence-map.json for source hashes and identity limits.

The IFC geometry-engine checks and coordinate/placement hashes are summarized in verification-summary.json. This package remains a reference-format candidate pending root review; it is not a fabrication release or engineering approval.
