I suspect this could be related to a corrupted Design View or something. I could be wrong but I cannot seem to reproduce it on my machine.

It was an iLogic trigged event. When I deleted it, the problem was gone.</P> Wed, 03 Dec 2025 08:12:59 GMT https://forums.autodesk.com/t5/inventor-forum/model-tree-collapses/m-p/13929697#M404466 Johan_Degreef 2025-12-03T08:12:59Z
