C3D-LW-PARKSTRIPE · Linework: parking stall stripes done
Draws 15 parking stall stripes on SS-ROAD-STRIPE, each an 18ft line across the two surveyed rows. The P STRIPE points are stalls, not a path - chaining them gave one meaningless 251ft polyline.
C# payload
// Parking stall striping -> SS-ROAD-STRIPE.
// The 32 "P STRIPE" points are NOT a path - they are two parallel rows at N=1280136.5 and
// N=1280154.5, 18ft apart (the stall depth), with points every ~8ft along each row (the stall
// width). Chaining them by proximity produced one meaningless 251ft polyline regardless of the
// gap threshold, because the spacing is uniform.
// Correct reading: each pair of opposite points is ONE STALL STRIPE, drawn across the 18ft.
// Near-duplicate shots of the same point (within 1ft) were merged first.
// Regular Polyline (cookbook 11). Host owns Tx; host regens after commit.
