C3D-0327 · Find the 4 bearing labels (408.70 / 79.34 / 1089.00 / 150.35) and what controls their weight [C3D-PSLREAD] done

Read-only. Enumerates every label entity in model space, matches the four distances, reports each one's handle, text, layer, lineweight and label style, plus a style census and the PROP/LABEL layer lineweights.

// Find the parcel segment labels carrying 408.70, 79.34, 1089.00, 150.35 and report everything
