C3D-HCWALAYERS2 · Create HCWA as-built layer set v2 (48 layers) done

Same as C3D-HCWALAYERS, renamed to avoid the stale duplicate-id collision. Additive only, nothing existing touched.

C# payload

// Create the HCWA as-built layer set (empty layers, exact names per the HCWA CAD Layers table).
// Additive only — no existing layer touched. Idempotent (skips layers that already exist).
// Colors: sewer=green(3), water=blue(5), hydrants=red(1), existing=8(gray), text=white(7),
// road=8, boundary/easement=6(magenta)/4(cyan), control=2(yellow).

Result

HCWA layers created: 47, already existed: 0, total in set: 47
VERIFY: 47/47 HCWA layers present.
DONE. All additive; no existing layers touched.
