The options located at the bottom of the object editor are available from any of the tabs, and are common to most objects. A description of each option follows:
The Apply button saves the changes made to all the tabs and, if applicable, updates the object in the viewer. Objects that depend on the edited object are also updated.
The Reset button returns the settings for an object to those stored in a database for all the tabs. The settings are stored in the database each time you click Apply.
The Defaults button restores the system default settings for all the tabs of an object. The system defaults are stored for each parameter, without regard for the types of object(s) in which the parameter may be used. For this reason, using the Defaults button may result in unsuitable changes to an object’s settings, and is not recommended.
