Get difference between two versions of the model

[supportT7RUE]

Hi there,

For any two given datetimes, I would like to get the list of all objects that got changed in the model, the list of newly created objects, and the list of all objects that got deleted from the model, between those datetimes. This is needed to build a diff to speed up the export time. Do you know if that's possible anyhow?

Thanks!

Yes, sure, there are several different approaches. I implemented a prototype or two myself way back then:

• Tracking Element Modification
• Implementing the TrackChangesCloud External Event

BIM 360 and APS, the Autodesk Platform Services, ex-Forge, also provide support for model comparison:
