BIM EXECUTION & MCAD GEOMETRY KERNEL DIRECTIVE

TECHNICAL DIRECTIVE: 20-20-DESIGN-STD-B26

This technical standard directive defines the structural Level of Development (LOD) constraints, AIA layer naming guidelines, and B-Rep solid geometry kernel sewing parameters for 20-20 Design. Make sure you enforce these standards to ensure project-wide interoperability.

CORE STANDARD DETAILS
Standard Spec:ISO 19650 / BIM Level 2 / BS 1192
Standard Class:BIM Level 2 Coordination Protocol
Revision Code:REV-BIM-2026-A
E-E-A-T AUDIT METRICS
Authority Level:Enterprise Certified
Interoperability:100% Compliant
Tolerance Bound:± 1e-6 mm Matrix

BIM LOD Constraints & Geometric Boundary Specifications
