C3D-0034 · READ-ONLY: enumerate parcels, areas and area labels [PARCEL-AREA-2] done

Why does the 30' S.S.E. parcel label 12600.25 sq ft when the outline measures 24157.56? Lists every site/parcel with area and bbox, and every parcel area label with the parcel it actually points at. No changes.

C# payload

// READ-ONLY. Enumerate every site, every parcel, its area, and every parcel area label with the
// parcel it actually points at.
//
// The question: the 30' S.S.E. parcel labels 12600.25 sq ft but the enclosed shape measures
// 24157.56. Either the label belongs to a different parcel than the outline (site topology split
// the easement at a crossing), or there are more parcels here than expected. Nothing is modified.
