C# payload

// Erase only the 33 Polyline3d entities on SS-V-ROAD-CURB (the straight-chord draft from C3D-TBCDRAW).
// That layer also carries 18 Lines, 15 Polylines, 11 FeatureLines, dimensions, a Hatch, Wipeout, and a
// Civil Site object that are pre-existing production content - leave all of that alone, only remove
// the Polyline3d type since that's exactly what was added.
