Integration from Module Schemas to Full Model

About

This must be done not by gurus—by clerks following specs.

Why? Because of this - [1]. In short: The real risk is not skill level—it’s unconscious substitution. The danger is not incompetence. The danger is: “I know a better way to do this.”

Howto

The core simplification: Assembly is not geometry. Assembly is topology. Geometry already exists at the module level. Assembly is simply how modules are connected.

If you accept that, everything downstream becomes tractable.

= Induction-Grade House Compiler Process (Modules → Assembly → Post-Compilers) = == Canonical Principle == All downstream artifacts are generated from: # ''Module Schemas'' (single-module truth) # ''Assembly Schema'' (topology truth: what connects to what) # ''Post-Compiler Passes'' (feature injection + routing + schedules) No manual CAD edits. Every output must be regenerable from schemas. == 0. Inputs and Conventions (Lock These In) == === 0.1 Coordinate and Reference Convention === * Each module has a local coordinate frame (CSYS) and published ports/faces. * The assembly has a world CSYS and places modules via topology constraints. * Every placed object is referenced by: * module_id * host reference (stud_id / bay_id / distance-along-wall s) * level (z) reference (finish floor, top plate, etc.) === 0.2 Module Interface Contract (Minimum) === Each module generator must publish: * Ports: left_end, right_end, top, bottom * Faces: interior, exterior, centerline * Stud map: stud centerlines + IDs (queryable by distance along wall) * No-go zones: openings, headers, shear zones, MEP prohibited zones * Feature lanes: permissible regions for blocking + services == 1. Generate Base Modules (Module Compilers) == This stage produces clean, reusable modules with metadata. No building-level logic. === 1.1 Wall Modules === * Inputs: width (nominal 4'), height (8–10'+), thickness, stud spacing, sheathing side(s) * Outputs: * Framing geometry (studs/plates) * Sheathing geometry * Tags: studs, plates, sheathing, cavity volumes * Ports/faces + stud map + lanes === 1.2 Door Modules === * Inputs: rough opening width/height, door type, header rule, king/jack rules * Outputs: * Framing + header + cripples + tags * Door opening volume (clearance/RO solid) * Ports/faces + stud map === 1.3 Window Modules === * Inputs: rough opening width/height, sill height, header rule * Outputs: * Framing + header + sill + cripples + tags * Window opening volume (RO solid) * Ports/faces + stud map == 2. Generate House Assembly (Assembly Compiler) == Assembly schema contains ONLY: * module instances (id, type, parameters, orientation) * connections (what connects to what) The assembly compiler: # Picks a root module and places it at origin. # Walks the adjacency graph and places all modules by port alignment. # Emits connection events (L-corner / T-intersection / splice). # Outputs the full placed assembly + adjacency graph. === 2.1 Assembly Schema (Topology Truth) === * modules[]: * module_id, module_type, params, orientation, level * connections[]: * A.port → B.port (and connection type if explicit) == 3. Post-Compiler Passes (Feature Injection + Routing) == Each pass is deterministic and idempotent: * Re-running a pass must not duplicate features. * Each pass outputs "feature objects" + materialized CAD + BOM deltas. == Pass Order (Recommended MVP → Full Build) == == 4.
