Thank you for your post.
Which unit preference is not being saved with the file? For Object Info, that information does get stored with the file, so once you change it, quit and relaunch, the unit settings should still be saved.
In the menu, under Models, Units... And yes, the Show Object Info does not stay also ! As soon as I close the file, when reopened, it comes back with previous settings, which are not showing object info, and inches for the units.
If the files are already hosted on FileMaker server, you'll need to close them down, open them directly with FileMaker Pro, set the units, close, and then open back up in Server. As always, be careful when doing this procedure, and keep a backup.
Thanks, it worked !
Effectively, they were hosted on a FileMaker server... But a layout needs to have a change to be saved, for the units and info box settings to be saved. Just to enter modify mode and changing those then exit was not enough...
