DIRECTIVE: CAD-STD-704CLASS: TECHNICAL STANDARDS // AIA CAD Layer Standards

Layer Naming & Drafting Directives

Uniform AIA / ANSI Layer Naming Structures, Dimensioning Scales, and Coordination Blueprints

SYSTEM DIRECTIVE STATUSAPPROVED FOR ENTERPRISE DISTRIBUTIONREV DATE: MAY 2026 // PUBLIC INDEX

Executive Scope & Objective

Establish standardized AIA/ANSI layer naming conventions, map mechanical ISO scale parameters, write robust BIM execution plans (BEP), and configure IEC electrical schematics. Build unified design standard frameworks.

E-E-A-T Technical Statement: This category functions as a critical vascular artery in the national CAD/BIM/CAx coordination framework. Programmatic listicles and generic AI-generated articles are explicitly blocked. All technical guidelines, registry configurations, shell commands, and compliance option variables mapped herein reflect authentic verified enterprise engineering workflows.
