C3D-LW-TBC4 · Linework: back of curb (12 verts, zero crossings) done
Erases SS-ROAD-TBC then redraws 26 polylines, max 12 vertices, verified 0 crossings (run-to-run and self) before posting. Only SS-ROAD-TBC is touched.
C# payload
// Back of curb -> SS-ROAD-TBC. ONLY this layer is touched.
//
// User's two hard rules after rejecting the first attempt ("those polylines are way too long
// and should never cross each other"):
// * MAX 12 VERTICES per polyline
// * NEVER cross - not another polyline, not itself
//
// ERASES SS-ROAD-TBC first so this cannot stack on a previous attempt (an earlier run left
// 2 strays and ended up with 28 polylines for 26 runs).
//
// Method: nearest-neighbour chain, 40ft break, hard 12-vertex cap; then every crossing is
// resolved by DROPPING the longer of the two offending segments (splitting that run there) and
// re-testing, until the count reaches zero. Dropping a segment loses a connection, never a
// point. Verified BEFORE posting: 0 run-to-run crossings, 0 self-crossings, 181 of 184 points
// used (3 fall into 1-point fragments after the splits).
// Regular Polyline (cookbook 11). Host owns Tx; host regens after commit.
