Shortest distance between the two surfaces in millimetres; 0 when the objects touch or intersect
Upper bound of the quantisation error in the reported distance, mm (the vertex positions are stored quantised)
The distance definition this result was measured with
The closest point on the first object, viewer measurement coordinates (mm, globalBaseTranslation subtracted)
The closest point on the second object
OptionalreferenceWhat the references measured to were: "axis", "centreLine" (a vertical centre line on at least one side) or "centreToCentre" (two vertical lines: between their middles, the objects' centre points, and in horizontal mode their distance in plan); null when both objects were measured on their surface
OptionalreferencePer object, whether it was measured on its surface or on its reference
OptionalreferencePer side, the level or grid line it holds instead of an object (docs/reference-geometry-measurement-design.md §12.4), or null
The result of an object distance measurement (docs/object-distance-measurement-design.md §6)
