TRAFFIC INDUSTRIES | TI-A2-FD750-DEV01

LOCAL REFERENCE CAD CANDIDATE — DEV01

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

This package contains byte-preserved native FreeCAD and STEP source geometry plus measured reference conversions. The source delivery record remains ADAY / INDEPENDENT_QA_PENDING. The documented overall envelopes are A2 200 x 200 x 750 mm and A3 1000 x 220 x 920 mm; other detailed dimensions remain proposals where the source parameter register classifies them as PROPOSED. Material grades are not selected.

Physical occurrence counts from the source tree and matching STEP are A2: 4 solids, A3: 5 solids. Native object names, STEP solid indexes, IFC names, GLB names and STL triangle ranges are mapped in native-occurrence-map.json. The STEP file does not retain the editable FreeCAD feature history.

Units: FreeCAD and STEP are mm. IFC4 declares mm. GLB is metres with Y up (CAD X,Y,Z -> GLB X,Z,-Y). STL carries no intrinsic unit; import it as millimetres. The existing DXF is the source native two-dimensional drawing with TOP, FRONT, SIDE, ISO, A-A and B-B layers in modelspace at 1:1 mm. It has no DIMENSION entities; dimension labels are on the PDF sheets. The DXF curves are polylines, with measured analytic-envelope deviations recorded in the DXF transfer report. DWG is ODA ACAD2018; its reopened DXF view coordinates and layers match the source file.

The three PDFs are approved English-language, print-only distribution copies of the current site sheets. They retain product identity and drawing geometry; original PDF sources and native CAD files remain unchanged.

A3 head direction was confirmed as GÖMME. The current model's Ø30 seat remains as modeled; no countersink angle or hardware standard was supplied or added. A2/A3 ground and substrate fixing design is not established.

This is not an approved fabrication drawing or manufacturing release. Do not infer tolerances, material grades, installation fixings, performance or regulatory compliance from this geometry. Root review and any separate design approval remain pending.
