C3D-LW-TBC · Linework: back of curb done
Draws 7 back-of-curb polylines on SS-ROAD-TBC from 184 TBC-family points, 60ft break threshold (chosen by testing 25/40/60/80/120).
C# payload
// Back-of-curb linework -> SS-ROAD-TBC.
// 184 TBC-family points chained nearest-neighbour from the outermost point, breaking a run when
// the next-nearest point is more than 60ft away. That threshold was chosen by testing 25/40/60/
// 80/120ft: 60 gives 7 runs using 182 of 184 points with only 2 runs under 30ft. Tighter
// fragments real curb, wider merges separate curbs into one polyline.
// Regular Polyline, never Polyline3d (cookbook 11). Host owns Tx; host regens after commit.
