Autodesk Inventor 2027 introduces a useful enhancement for drawing automation with the addition of ReplaceBOMView support for Balloons and Parts Lists. This improvement provides greater flexibility when working with Bill of Materials (BOM) representations directly within drawings.
🚀 What’s New?
In previous versions, modifying the BOM view associated with balloons or parts lists required manual adjustments or recreation of these objects.
With Inventor 2027, new API methods have been introduced to simplify this process:
Balloon.ReplaceBOMViewPartsList.ReplaceBOMView
These methods allow developers to dynamically change the BOM view linked to balloons and parts lists without needing to recreate them.
🔧 Key API Enhancements
1. Balloon.ReplaceBOMView
The ReplaceBOMView method for the Balloon object allows you to update the BOM view associated with an existing balloon.
Key Benefits:
- Avoid recreating balloons when BOM view changes
- Maintain annotation consistency
- Improve automation workflows
2. PartsList.ReplaceBOMView
The ReplaceBOMView method for the PartsList object enables updating the BOM view for an existing parts list.
What this enables:
- Seamless switching between BOM views (e.g., Structured, Parts Only)
- Retain formatting and layout of the parts list
- Reduce manual rework in drawing updates
💡 Why This Matters
Managing BOM views is a common requirement in drawing documentation. This enhancement provides:
✔ Improved Efficiency
Update BOM views without deleting and recreating annotations
✔ Better Automation
Programmatically control BOM representation in drawings
✔ Consistency in Documentation
Preserve existing balloons and parts lists while updating their data source
🧩 Sample Use Case
Consider a drawing where the BOM view needs to switch from Structured to Parts Only:
With the new API support, you can:
- Update the parts list to reflect the new BOM view
- Ensure all balloons remain linked correctly
- Avoid recreating annotations manually
🔍 Notes
- These methods apply to existing Balloon and PartsList objects
- Ensure the target BOM view is valid and available in the document
- Helps maintain annotation integrity during BOM updates
🏁 Conclusion
The introduction of ReplaceBOMView support for Balloons and Parts Lists in Inventor 2027 significantly improves drawing automation capabilities.
By leveraging Balloon.ReplaceBOMView and PartsList.ReplaceBOMView, developers can create more efficient, flexible, and maintainable workflows without disrupting existing annotations.
This enhancement is especially valuable for teams managing dynamic BOM configurations and complex assemblies.
