Hi,
This is a known limitation of ARCHICAD, as the Detail Tool was developed a long time ago, before the live views (like Sections or Elevations) were developed.
It's more typical for sections and elevations to be changed more often than for details. Also the Renovation function came many years later and it was not possible in the scope of the project to have Details re-worked to accommodate this one item.
Let me share a video from Nick Cornia, GRAPHISOFT NA, it explains very well the situation:
https://www.dropbox.com/s/uoqy94zlqyuz9s7/Detail%20Tool%20Update%20Renovation%20Status.mov?dl=0
There is a possible workflow to change the contents of the detail, but not the PSD/Reno settings in the View Settings:
1. Open the detail
2. Change PSD/Reno settings (you'll get notifications that you need to rebuild the View)
3. Rebuild the View. Changes made earlier will be lost.
4. The View will keep these updated contents, unless you rebuild it from the source View again.
Regards,
Noemi
