C3D-0328 · Dump ParcelSegmentLabel properties - find how the distance text is exposed [C3D-PSL2] rejected

Read-only. Reflects every property on the first segment label so we can see where 408.70 / 79.34 / 1089.00 / 150.35 live, then lists all 21 with handle, layer, style and labelled feature.

C# payload

// The 21 ParcelSegmentLabels gave no text via Text/LabelText. Dump every readable string
// property on each one so we can see how the distance is exposed, plus geometry so the four
// can be matched by the underlying segment length if the text is not reachable.
