C3D-0298 · 260610 Tara Blvd: read all area labels and measure the geometry done

READ-ONLY. Lists every label mentioning SQ FT / ACRES / SF in any space, then the measured area of every closed model-space polyline and every Civil parcel, so each label can be checked against real geometry.

C# payload

// READ-ONLY: every label mentioning an area (SQ FT / ACRES / SF), plus the measured area of every
// closed polyline and Civil parcel, so each label can be checked against real geometry.
