You may want to consider creating a backup of your profile(s) in AutoCAD. Some add-ons may modify the profile in code (ours don’t) and you may make unintentional changes to the profile yourself.
Backup Procedure:
- Issue the OPTIONS command.
- Select the PROFILES tab (your current profile is highlighted).
- Click the [Add to List] button.
- Enter a useful name, like MyProfileBackup.
Restore Procedure:
- Issue the OPTIONS command.
- Select the PROFILES tab.
- Select the backup profile in the list.
- Click the [Set Current] button.
- Select the old (corrupt) profile.
- Click [Delete] and confirm to remove it.
- Select the backup profile in the list again.
- Click the [Add to List] button.
- Enter the original profile (recently deleted) name.
- Select the original profile in the list.
- Click the [Set Current] button.
