# Batch CAD/BIM Converter ## Business Case ### Problem Statement Large projects and archives contain hundreds or thousands of CAD/BIM files: - Manual conversion is tedious and error-prone - Different formats require different converters - Progress tracking is needed for long operations - Error handling is critical for large batches ### Solution Unified batch converter handling all supported formats with progress tracking, error recovery, and consolidated reporting. ### Business Value - **Multi-format** - Revit, IFC, DWG, DGN in one workflow - **Error recovery** - Continue on failures - **Progress tracking** - Monitor large batches - **Reporting** - Consolidated conversion results ## Python Implementation ```python import subprocess from pathlib import Path from typing import List, Optional, Dict, Any, Callable from dataclasses import dataclass, field from datetime import datetime import time import json from enum import Enum from concurrent.futures import ThreadPoolExecutor, as_completed class CADFormat(Enum): """Supported CAD/BIM formats."""
