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.
