Process any IFC file (2x3, 4x, 4.3)\n- **No licenses** - Works offline without BIM software\n- **Data extraction** - All properties, quantities, materials\n- **3D geometry** - Export to Collada DAE format\n- **Pipeline ready** - Integrate with ETL workflows\n\n## Technical Implementation\n\n### CLI Syntax\n```bash\nIfcExporter.exe [options]\n```\n\n### Supported IFC Versions\n| Version | Schema | Description |\n|---------|--------|-------------|\n| IFC2x3 | MVD | Most common exchange format |\n| IFC4 | ADD1 | Enhanced properties |\n| IFC4x1 | Alignment | Infrastructure support |\n| IFC4x3 | Latest | Full infrastructure |\n\n### Output Formats\n| Output | Description |\n|--------|-------------|\n| `.xlsx` | Excel database with elements and properties |\n| `.dae` | Collada 3D geometry with matching IDs |\n\n### Options\n| Option | Description |\n|--------|-------------|\n| `bbox` | Include element bounding boxes |\n| `-no-xlsx` | Skip Excel export |\n| `-no-collada` | Skip 3D geometry export |\n\n### Examples\n\n```bash\n# Basic conversion (XLSX + DAE)\nIfcExporter.exe \"C:\\Models\\Building.ifc\"\n\n# With bounding boxes\nIfcExporter.exe \"C:\\Models\\Building.ifc\" bbox\n\n# Excel only (no 3D geometry)\nIfcExporter.exe \"C:\\Models\\Building.ifc\" -no-collada\n\n# Batch processing\nfor /R \"C:\\IFC_Models\" %f in (*.ifc) do IfcExporter.exe \"%f\" bbox\n```\n\n### Python Integration\n\n```python\nimport subprocess\nimport pandas as pd\nfrom pathlib import Path\nfrom typing import List, Optional, Dict, Any, Set\nfrom dataclasses import dataclass, field\nfrom enum import Enum\nimport json\n\n\nclass IFCVersion(Enum):\n \"\"\"IFC schema versions.\"\"\"\n IFC2X3 = \"IFC2X3\"\n IFC4 = \"IFC4\"\n IFC4X1 = \"IFC4X1\"\n IFC4X3 = \"IFC4X3\"\n\n\nclass IFCEntityType(Enum):\n \"\"\"Common IFC entity types.\"\"\"\n IFCWALL = \"IfcWall\"\n IFCWALLSTANDARDCASE = \"IfcWallStandardCase\"\n IFCSLAB = \"IfcSlab\"\n IFCCOLUMN = \"IfcColumn\"\n IFCBEAM = \"IfcBeam\"\n IFCDOOR = \"IfcDoor\"\n IFCWINDOW = \"IfcWindow\"\n IFCROOF = \"IfcRoof\"\n IFCSTAIR = \"IfcStair\"\n IFCRAILING = \"IfcRailing\"\n IFCFURNISHINGELEMENT = \"IfcFurnishingElement\"\n IFCSPACE = \"IfcSpace\"\n IFCBUILDINGSTOREY = \"IfcBuildingStorey\"\n IFCBUILDING = \"IfcBuilding\"\n IFCSITE = \"IfcSite\"\n\n\n@dataclass\nclass IFCElement:\n \"\"\"Represents an IFC element.\"\"\"\n global_id: str\n ifc_type: str\n name: str\n description: Optional[str]\n object_type: Optional[str]\n level: Optional[str]\n\n # Quantities\n area: Optional[float] = None\n volume: Optional[float] = None\n length: Optional[float] = None\n height: Optional[float] = None\n width: Optional[float] = None\n\n # Bounding box (if exported)\n bbox_min_x: Optional[float] = None\n bbox_min_y: Optional[float] = None\n bbox_min_z: Optional[float] = None\n bbox_max_x: Optional[float] = None\n bbox_max_y: Optional[float] = None\n bbox_max_z: Optional[float] = None\n\n # Properties\n properties: Dict[str, Any] = field(default_factory=dict)\n materials: List[str] = field(default_factory=list)\n\n\n@dataclass\nclass IFCProperty:\n \"\"\"Represents an IFC property.\"\"\"\n pset_name: str\n property_name: str\n value: Any\n value_type: str\n\n\n@dataclass\nclass IFCMaterial:\n \"\"\"Represents an IFC material.\"\"\"\n name: str\n category: Optional[str]\n thickness: Optional[float]\n layer_position: Optional[int]\n\n\nclass IFCExporter:\n \"\"\"IFC to Excel converter using DDC IfcExporter CLI.\"\"\"\n\n def __init__(self, exporter_path: str = \"IfcExporter.exe\"):\n self.exporter = Path(exporter_path)\n if not self.exporter.exists():\n raise FileNotFoundError(f\"IfcExporter not found: {exporter_path}\")\n\n def convert(self, ifc_file: str,\n include_bbox: bool = True,\n export_xlsx: bool = True,\n export_collada: bool = True) -> Path:\n \"\"\"Convert IFC file to Excel.\"\"\"\n ifc_path = Path(ifc_file)\n if not ifc_path.exists():\n raise FileNotFoundError(f\"IFC file not found: {ifc_file}\")\n\n cmd = [str(self.exporter), str(ifc_path)]\n\n if include_bbox:\n cmd.append(\"bbox\")\n if not export_xlsx:\n cmd.append(\"-no-xlsx\")\n if not export_collada:\n cmd.append(\"-no-collada\")\n\n result = subprocess.run(cmd, capture_output=True, text=True)\n\n if result.returncode != 0:\n raise RuntimeError(f\"Export failed: {result.stderr}\")\n\n return ifc_path.with_suffix('.xlsx')\n\n def batch_convert(self, folder: str,\n include_subfolders: bool = True,\n include_bbox: bool = True) -> List[Dict[str, Any]]:\n \"\"\"Convert all IFC files in folder.\"\"\"\n folder_path = Path(folder)\n pattern = \"**/*.ifc\" if include_subfolders else \"*.ifc\"\n\n results = []\n for ifc_file in folder_path.glob(pattern):\n try:\n output = self.convert(str(ifc_file), include_bbox)\n results.append({\n 'input': str(ifc_file),\n 'output': str(output),\n 'status': 'success'\n })\n print(f\"✓ Converted: {ifc_file.name}\")\n except Exception as e:\n results.append({\n 'input': str(ifc_file),\n 'output': None,\n 'status': 'failed',\n 'error': str(e)\n })\n print(f\"✗ Failed: {ifc_file.name} -
