• To specify the default setting in the Reference Control dialog box for reference handling, set the configuration file option scope_invalid_refs to prohibit or copy.

• To set the default reference scope and not allow anyone to change that setting, specify the appropriate value for default_ext_ref_scope. Then set the configuration file option allow_ref_scope_change to no (yes is the default). You cannot use this option unless you have set default_ext_ref_scope.

• To specify the default settings for the reference control in a new object, set the configuration file option default_object_scope_setting to all (the default), none, skeletons, or subassemblies.

• To specify the default setting in the Reference Control dialog box for reference handling of new objects, set the configuration file option default_object_invalid_refs to prohibit or copy.

• To ignore object-specific reference scope settings, set the configuration file option ignore_all_ref_scope_settings to no(yes is the default). The Environment scope settings will still be enforced.
