Supported templates

The source of truth for role inventory is beamng.cad/FramePipeline/template_catalog.json. Physical generation also validates the reviewed definition; a catalog entry alone does not mean a complete vehicle can be generated.

Template	Required review
Front double wishbone	Upper/lower arm pivots, upright ball centres, steering links, shock eyes and wheel axes
Rear trailing arm	Actual chassis hinge and wheel support geometry
Rear double wishbone	Both arms, upright, locating links, shock and wheel axes
Trailing arm + radius rods + toe link	Two chassis ball centres, separate ball carrier and all three rods
Ball-pivot trailing arm + radius rods + hinged upright + toe link	One chassis ball, arm/upright hinge and explicit rod topology
MacPherson strut	Inventory schema for future work; not supported full-vehicle generation
CVT rear drive	Engine/clutch/CVT, rear reduction/differential and actual ratios
CVT rear drive with geared front output	Additional front output gearing, propshaft and front differential

Role ownership

Each physical body belongs to one owner. Independently moving arms, racks, coilover members, carriers and wheels must not be treated as one rigid object. Repeated panels and shaft sections are allowed; unique required roles cannot be duplicated.

Changing setup preserves saved selections and marks irrelevant tags OUTSIDE CURRENT SETUP. Resolve those entries, missing roles and duplicate ownership before packaging.

Hardpoints

Hardpoints are coordinates or directed axes captured from CAD or supplied in an explicitly reviewed definition. A hub_axis record is a second point, not a free direction vector. FL/FR and RL/RR refer to vehicle left/right as seated facing forward.

Example skeletons illustrate requests; they never assign real hardpoints. Frame mount plans must be recalibrated when the physical topology changes.

See Suspension setup and Joint authoring for the procedures.
