| # BIM Design Philosophy | # BIM Design Philosophy |
| The Building Design System serves as the AEC-specific extension of Foundry’s design substrate, analogous to the relationship between IBM Carbon and specialized industry modules. It is anchored to the IFC 4.3 entity hierarchy and prioritized for high-fidelity operational environments. The system translates Foundry’s core commitments—flat-file storage, open standards, and offline-first execution—into a professional toolset that addresses the structural weaknesses of legacy cloud-only BIM. | The Building Design System serves as the AEC-specific extension of Foundry’s design substrate, analogous to the relationship between IBM Carbon and specialized industry modules.

| Foundry introduces a "compositional-first" approach to building codes and jurisdictional rules. Instead of post-design validation, cities are intended to publish codes as composable design tokens (bSDD dictionaries + IDS 1.0 constraints). Designers then assemble models within pre-constrained envelopes where violations become geometrically impossible by construction. | Foundry introduces a "compositional-first" approach to building codes and jurisdictional rules.

| This shift from "check-after-design" to "compliant-by-construction" represents a significant leapfrog in AEC technology (Proposed Doctrine Claim #41). | This shift from "check-after-design" to "compliant-by-construction" represents a significant leapfrog in AEC technology (Proposed Doctrine Claim #41). |
