The distance in millimetres, or null while there is no result
The point being dragged (see editable): its index, whether it moved yet, and the measurement's value before the drag as its label shows it. Null when no point is dragged. A right-click during the drag puts the point back, like Escape. For a laser, index is the beam end dragged along its beam (0-2 the ends along the axes, 3-5 those opposite), null while it moves as a whole by its instrument; originalText is null

The distance definition of this measurement
The points placed so far while this measurement is being taken (objects picked, for an object distance)
The qids of the two objects (null for a slot that has not been picked yet)
Per object, whether it is measured on its surface or on its reference (centre line / axis plane)
Per side, the level or grid line it holds instead of an object, or null
Whether the measurement goes to the references of its objects: while picking the choice made with preferReference, once finished whether a slot actually uses its reference
The references of the two objects once they have been fetched (the first O key press fetches them), null per object without one
The result, or null while the objects are still being picked or the distance is being computed
Whether the points of this measurement snap to vertices and edges (point, length, area, angle)
Whether the O key can cycle this measurement's reference modes: it is finished and both objects are known
Whether finish() would complete this measurement now (enough points for a length or an area)
Move to the next reference-mode state and recompute (the O key): surface/surface, then B on its reference, both, A alone, skipping states an object without a reference cannot take. Fires committed again on the new result.
true when the modes changed; false when neither object has a reference, or while a computation is still running
The points (viewer measurement coordinates) a camera fit on this measurement encloses, or null when it has none yet
Whether this measurement is hovered
Whether this measurement is selected
Before the second object is picked: measure to the objects' references (a slot whose object has none stays on its surface) or to their surfaces
Whether the choice could be made (not once finished, use cycleReferenceMode then)
One object's Centre line toggle (0 the first object, 1 the second): whether it is measured on its reference, and whether that can be switched: not for a level or grid line, nor, once the references are in, for an object without one. In vertical mode a vertical centre line (a window's, a column's axis) is measured from its middle, the object's centre height
Remove this Measurement
Measure one object (0 the first, 1 the second) on its reference or on its surface, the other staying as it is: a choice for the computation while picking, a recomputation once finished (fires committed again, as cycleReferenceMode)
Whether the modes changed; false when the object has no reference (a message says so)
Remove the last placed point while this measurement is being taken, see Measuring.undoLastPoint
Whether a point was taken back
Whether the points of this measurement can be dragged to a new position after it has been finalized (default true). Supported for area, path and point measurements, and for the laser, which is dragged as a whole by its instrument (a click on it selects it instead); the other types have no draggable points. The points show a pointer cursor on hover; while dragging, vertex snapping applies as during measuring (Shift temporarily disables it) and the label (area/length/position) is updated in realtime. Dropping the point fires the committed listener event, Escape cancels the drag
