Setting Class and Design Layer Options

The Class Options and Layer Options commands are very similar—they both control how all the classes or design layers in a drawing work together. For example, a drawing project can be set to display only the active class, temporarily hiding all objects assigned to other classes.

To change the options for displaying, snapping to, and editing objects in the current class or design layer:

1.	Select View > Class Options (or Layer Options) and then the option.

Class and design layer options can also be accessed with the Class Options and Layer Options commands on the document context menu.

 

Parameter	Description
Active Only	Displays only objects in the active class/layer; only the active class/layer prints
Gray Others	Displays the active class/layer normally and all other classes/layers appear dimmed (except for those set to invisible); even though visible, objects in dimmed classes/layers cannot be edited
Gray/Snap Others	Displays the active class/layer normally and all other classes/layers appear dimmed (except for those set to invisible); objects in any normally displayed or gray class/layer can be snapped to. Only objects in the active class/layer can be edited.
Show Others	All classes/layers display normally, except for those set to invisible or grayed; even though visible, objects in classes/layers other than the active class/layer are not editable and cannot be snapped to
Show/Snap Others	All classes/layers display normally, except for those set to invisible or grayed; objects in any normally displayed or gray class/layer can be snapped to. Only objects in the active class/layer can be edited.
Show/Snap/Modify Others	All classes/layers display normally, except for those set to invisible or grayed. Objects in any normally displayed or gray class/layer can be snapped to; only objects in normally displayed classes/layers can be edited. Locked objects display with selection handles that appear dimmed.

2.	The current class or design layer display changes accordingly.
