C3D-260619-R5713 · Redline 5,7,13 - power line, adjoiner DB/PG, septic note done

Draws the overhead power line through the surveyed PP/OHP points using the POWER_LINE linetype with a label; adds a DB/PG placeholder for Thomas & White (the only adjoiner missing one); adds a sewage-disposal/water-supply note flagging that no septic tank or drainfield was located by this survey.

C# payload

// REDLINE #5, #7, #13.
//  #5  Overhead power line - the POWER_LINE linetype ("----P----P----") is already loaded in
//      this drawing. Draws a polyline through the surveyed PP / OHP points along the Stonewall
//      Tell frontage and applies that linetype, plus an "OVERHEAD POWER LINE" label.
//  #7  Adjoiner deed references. MNSF II W1 LLC (DB 51448 PG 269), McAulay/Groce (DB 52044
//      PG 322), Powell (DB 28196 PG 23) and Vaughan (DB 30326 PG 474) ALREADY carry DB/PG on
//      the drawing - only Thomas & White lacks one, so a placeholder block is added for it.
//  #13 No septic tank or drainfield points exist in the survey data, so a sewage-disposal /
//      water-supply note is added with the location flagged as to-be-verified.
// Model space, model units (1 paper inch = 60 model units at the sheet viewport scale).
// ADDS ONLY. Host owns Tx; host regens after commit.
