Automate BOM Extraction from Autodesk Inventor Assembly to Excel using Python Description: This Python script is designed to automate the extraction of the Bill of Materials (BOM) from an Autodesk Inventor assembly (.iam) file and save it as a well-formatted Excel spreadsheet (.xlsx). It streamlines the BOM generation process, ensuring accurate data collection and reducing manual effort. Key Features & Benefits: ✅ Seamless Autodesk Inventor Integration Automatically connects to Autodesk Inventor and opens an assembly file. Uses Inventor’s BOM API to extract structured part data. ✅ Detailed BOM Information Extracts Part Numbers, Quantities, and Descriptions of components. Reads properties from Inventor's metadata, ensuring accuracy. ✅ Excel Export with Formatting Saves BOM data into an Excel spreadsheet (.xlsx) for easy sharing. Uses Pandas for structured formatting and better readability. ✅ Improves Productivity & Reduces Errors Eliminates manual BOM creation, saving time and reducing mistakes. Ensures consistency in part numbering and descriptions. ✅ Customizable & Expandable Modify to include additional fields like material, weight, cost, or supplier details. Can be extended to process multiple assemblies automatically. Who Can Benefit? ✔ Mechanical Engineers & Designers who need quick and accurate BOMs. ✔ Manufacturing & Procurement Teams for inventory management. ✔ Product Developers & 3D Printing Enthusiasts optimizing part lists. ✔ Python Developers & Automation Engineers exploring the Inventor API. Why Choose This Script? 🚀 Speeds up BOM generation by automating the entire process. 🔄 Ensures accurate & structured data directly from the CAD model. 🛠 Flexible and scalable to match your project needs. Get Started Today! Automate your BOM extraction with this powerful Python script, and take your design efficiency to the next level!
