  • Project created as the vehicle-side home for the 1995 Geo Tracker — bodywork and factory specs, distinct from cluzter (wiring), hardcut (ignition cut) and offroad-armour (underbody armour) — kickfix
  • Transcribed the GM SAE J1100 “Vehicle Dimensions” sheet (Geo Tracker, MY1994, issued 9-93, 2-door convertible + hardtop) verbatim from the Tailscale knowledgebase: wheelbase 2200, length 3620, width 1630, height 1654 4WD / 1633 2WD, 45.0° windshield, 15.5° tumble-home, curb masses, fiducial marks — geo-tracker-body-dimensions-sae-j1100
  • Recorded the retrieval gotcha: WebFetch returns only the mkdocs nav shell for knowledgebase pages; the actual table needs curl + HTML strip — geo-tracker-body-dimensions-sae-j1100
  • Flagged that approach / departure / ramp-breakover angles did not survive OCR (three unmapped pairs 40/37, 40/38, 23/21) — must not be cited without re-reading the scan — geo-tracker-body-dimensions-sae-j1100
  • Built a 33-named-body whole-body Fusion 360 model as a canvas for marking repairs — Y=0 at the front axle, +Y rearward, Z=0 at ground; bumpers at Y −655 / 2965; painted, trimmed and glazed appearances — geo-tracker-body-model-fusion
  • Documented every assumption not from the sheet (cowl at Y 664, door/fender splits at 425/430 and 1425/1430, greenhouse 800→664 half-width, 205/75R15 688 mm OD, 430 mm arch radius, 24 mm flare lip, panel thicknesses) — geo-tracker-body-model-fusion
  • Recorded the unresolved length discrepancy: tailgate spare reaches Y 3180 → 3835 mm overall vs documented L103 3620 — geo-tracker-body-model-fusion
  • Logged two open questions for the user: MY1994 sheet vs 1995 car, and 85 kW vs the G16B’s ~70–71 kWkickfix
  • Fusion gotchas 10 (compose the cut tool — sequential cuts union, never intersect) and 11 (OrientedBoundingBox3D.create throws on negative length from unsorted mirrored extents) written to fusion360-mcp-scripting; gotcha 7 extended to cover appearances, not just names
  • Initialized activity log.
