ODA Library fails to process Revit "Parts"

[mosment3DRepo]

Description

Revit contains a feature called "Parts" (https://knowledge.autodesk.com/support/revit/learn-explore/caas/CloudHelp/cloudhelp/2021/ENU/Revit-Model/files/GUID-22D24055-61A2-40BB-A2F7-A37990300B2B-htm.html)

This tends to create a subdivision of an element into multiple Parts. When these are used and the Revit 3D View settings are set to
3D View > Graphics > Parts Visibility = Show Parts
The ODA library crashes when processing.

When the same model has it's view settings changed to
3D View > Graphics > Parts Visibility = Show Original
The model processes but we lose the intelligence of the subdivision

• This is happening in: both
• This requires a hotfix to production: no

Steps to replicate

• This model works: Show Original
• This model doesn't work: Show Parts
• They are the same model but with different view settings (as above)

Expected Behaviour

• Models created using Parts should process correctly and show the elements as separate items in the tree

May need to rerun the model and check whether this is still a problem
