Glossary

Term	Meaning here
Body	One native solid or surface body within a CAD part instance
Component / owner	The project group responsible for geometry and physical mass
Persistent reference	Native identity used to resolve saved CAD selections after reopening
Companion assembly	Separate working assembly for reference/mate authoring
Hardpoint	Explicit location required by a mechanism or mounting definition
Node	Point with position and mass in the JBeam graph
Beam	Constraint acting between nodes; type determines its force law
Torsion bar	Four-node angular constraint; not necessarily a visible physical bar
Hull	Generated envelope/graph used by a representation
Fixture	Reviewed support/load sites for calibration or a test
COM	Centre of mass
Inertia tensor	Resistance to angular acceleration about specified axes
Prop	Rigid rendered mesh bound to a native node basis
Flexbody	Rendered mesh mapped to a set of physical nodes
Pressure wheel	Native BeamNG wheel/tire structure with generated nodes and pressure
Preload	Spring force already present at the selected reference pose
Motion ratio	Relationship between wheel travel and shock travel
Numerical conditioning	Adjustment within the discrete model’s mass/stiffness/damping limits
Provenance	Recorded identities and hashes tying output to its inputs
Receipt	Saved result and provenance for a build, revision, verification or installation
Pilot	Limited initial screen, not the full acceptance suite
Qualification	Accepted result for an explicitly stated scope and exact artifact
Visual only	Appearance following a physical parent; may transfer mass or explicitly exclude it
FL / FR / RL / RR	Front left / front right / rear left / rear right from the seated driver’s perspective

Vehicle axes are +X left, −Y forward, +Z up, in metres. The CAD transform is applied once, preserving the assembly origin.
