BLANK lets you blank, or hide, instance-specific entities
in a drawing instance. Blanking lets you mask entities
individually, not just by level. If you use BLANK, don't
worry, you aren't really deleting or erasing the entity, 
CADKEY just blocks the entity from view. 

The active instance is surrounded by a dashed 
highlighted box.

Use an option from the Selection Menu to choose the 
entities that you want to blank. Press <Enter> when you
finish choosing entities to blank. 

The entities you select disappear from the active drawing
instance only.

If some of the entities are difficult to select in your
active instance, you can select them from other instances
where they're easier to reach. However, remember that
BLANK makes the entities disappear from the active
instance only; you're using the entities in the other
instances as references and they are not affected.

To redisplay something that you've blanked,
you use UNBLANK.

Blanking is for instance-specific entities only. You can 
delete layout-specific entities using CADKEY's DELETE
option or (Ctrl)-(Q).

Press (F10) to return to the MODIFY menu.
