Propagation of attribute and graphic settings

Changes to the default value and visibility setting of an attribute, Symbol Wizard, or custom property value are propagated to child objects, unless the value or visibility setting has been overridden in a derived (child) object. We assume that you do not want to lose an override you entered for a child object due to a change made to the parent.

If a default value is changed in the parent object, but the value has not been overridden in a derived object, the new default value propagates from the parent to child objects where the default value has not been modified.

Likewise, if a visibility setting is changed in a parent template, the change propagates to unmodified child templates. If the visibility setting was modified in the child, the change in the parent does not propagate.
