After installing Inventor 2024, diameter dimensions are created without any visible value or diameter symbol.
Hole notes are also missing the diameter symbol and value.
If previous versions of Inventor are still installed it may affect them as well.
AutoCAD dimensions diameter dimensions are not affected, they display the diameter symbol and value.
Restarting the system should resolved the problem.
If there are pending Windows Updates run them and restart.
If it doesn't resolve it, uninstall Inventor 2024 from Windows Control Panel and reinstall from a full download in your Autodesk Account.
