In AutoCAD Mechanical 2025, the Activity Insights now logs more activities and provides more detailed information about drafting standards and symbol revisions.
The "Drafting standard changed" event is logged whenever there are modifications to the drafting standard in AutoCAD Mechanical. This event is triggered when you make changes in the Options dialog box (Standard TabStandards dropdown list), or by using the AMSETUPDWG command.
The "Symbol revision changed" event is created whenever there are modifications to the symbol revision in AutoCAD Mechanical. This event is triggered when you make changes in the Options dialog box (Standards tabStandard elements).
