  • Cross-linked to the new kickfix project — the same 1995 Geo Tracker now has documented factory body dimensions (geo-tracker-body-dimensions-sae-j1100) and a whole-body Fusion model (geo-tracker-body-model-fusion); Fusion gotchas 10–11 came from that build
  • Project created for offroad underbody armour CAD work — two unrelated vehicles, two separate Fusion documents, one shared toolchain — offroad-armour
  • Modelled a five-segment WH Grand Cherokee skid plate set (4 mm plate, 30 mm flanges, stations Y 350–3800, 150 mm gap before the tank plate); all dimensions provisional estimates from published WK/WH platform figures, not measured — wh-grand-cherokee-skid-plate-set
  • Cut “JEEP” through segment 01 at 180 mm cap height on the plate’s bottom face; the P’s counter needed two 7 mm stencil tie bars. Flagged that a 180 mm through-cut weakens the highest-impact plate and packs with mud — engrave or relocate offered — wh-grand-cherokee-skid-plate-set
  • Modelled a Geo Tracker / Sidekick front differential shield: 3/16 in steel faceted cradle, 895 cm³, ~7.0 kg, sized around a 230 mm assumed-pumpkin sphere at 30 mm clearance — geo-tracker-front-diff-shield
  • Negative research result recorded: no published dimensional data exists for the Sidekick/Tracker front diff housing (vendors, spec pages, forums all checked). Confirmed facts that were found — aluminium front housing, 6.9 in rear ring gear, 5.12/4.62 ratios, 1.82/1.00 t-case, XL7/Grand Vitara steel housing swap — with sources — geo-tracker-front-diff-dimensions-research
  • Fusion API gotchas 5–9 (silent CombineFeatures no-op, TimelineObject deletion order, body rename timing, orphan glyph counters, bottom-face text sketching) originated in this work and were written to fusion360-mcp-scripting
  • Initialized activity log.
