C3D-HCWALAYERS · Create HCWA required layer set (exact names) done

Creates all 70 HCWA-required layers with names matching the HCWA CAD Layers table exactly (Rev 1.6). ADDITIVE ONLY - creates layers, moves no entities. Idempotent. Foundation for the layer migration tickets. Drawing currently has ZERO HCWA-compliant layer names.

Result

HCWA layers created: 68, already existed: 0, verified present: 68/68
Additive only — no entities were moved. Layer names match the HCWA CAD Layers table exactly.
