FreeCAD drops timestamped .FCBak backups next to saved documents;
one slipped into the previous commit. Remove it and ignore the
pattern so only the real .FCStd models are versioned.
Owner corrected the variant: it is the 12 m Axer (11.99 x 2.50 m),
not the 12.8 m. Sweep the repo with the researched figures: PTAC
18000 kg (official prospectus, three concordant sources — the
18500/19000 ad-grade values were wrong), PV ~11500 kg for the 12 m,
wheelbase 6270 mm, C954E axle figures kept as labeled extrapolation.
Research report annotated, vehicle sheet and weight tracker updated,
FreeCAD dimension sheet recalibrated (11400 x 2440 x 2010 interior
placeholders).
Owner confirmed the long-wheelbase 12.8 m Axer. Pin it in the vehicle
sheet with the matching PTAC order of magnitude (~19 t, ad-grade,
official value still to be read on the plate), and bump the FreeCAD
interior-length placeholder from a 12 m guess to 12300 mm so the
parametric zoning reflects the right envelope until the real survey.
Third leg of the CAD tooling: FreeCAD 1.1 for 3D and dimensioned
technical drawings. Seed a spreadsheet-driven model of the interior
(envelope, 9-seat zone, shower cell, Tiroclass bench, fab-machine
zone) so the survey of the emptied bus only has to fill in the
dimension sheet to recalibrate the whole layout. Conventions and
planned files documented in the folder README; decision registered.
