AEC & BIM

Profile: aec · Model: FLAGSHIP (gpt-5.6-sol) · Chunking: table_aware · Confidence: ≥ 0.75

Overview

Parse IFC models, CAD drawings, and AEC specification documents to extract structured entities and relationships for clash detection, compliance checking, cost estimation, and facility management.

Extracted entities

Entity type	Examples
IfcElement	Columns, beams, slabs, walls, doors, windows — with properties
IfcSpace	Rooms and zones with area, volume, occupancy
IfcMaterial	Material names and specifications
IfcSystem	MEP systems — HVAC, plumbing, electrical
RegulatoryCode	Eurocodes (EN 1990–1999), IBC, NFPA, ISO standards
IfcClassification	Uniclass, OmniClass, Uniformat codes

Extracted relationships

MADE_OF · LOCATED_IN · CONTAINS · CONNECTS_TO · CLASSIFIED_AS · COMPLIES_WITH

Supported formats

Format	Notes
IFC (.ifc, .ifczip)	10-section structured output covering storeys, spaces, elements, MEP, materials, quantities, property sets
DXF (.dxf)	Layers, entities, blocks, dimensions, text
DWG (.dwg)	Via LibreDWG conversion to DXF
STEP (.step, .stp)	Assembly tree, part names, B-rep metadata
STL (.stl)	Triangle count, bounding box, part name
OBJ (.obj)	Mesh groups, material references
GLTF / GLB	Scene hierarchy, mesh names, materials
G-code	Tool paths, layer count, estimated print time

Typical workflow

IFC model upload
    ↓
DocIntel (aec profile) → entities + relationships
    ↓
Purple8 Graph → knowledge graph storage
    ↓
Cortex / AI Architect → clash detection, compliance queries, cost estimation

Example

curl -X POST http://localhost:8200/process \
  -H "Authorization: Bearer $API_KEY" \
  -F "file=@building-model.ifc" \
  -F "profile=aec"

TIP

Confidence scores shown are calibrated (post-temperature scaling). The AEC profile uses FLAGSHIP model tier and ≥ 0.75 threshold for maximum precision on structural data.
