If you are working on a large
project, turning off the display of some objects in the specifications tree
can reduce visual "clutter" in the tree. Turning off an object in the tree
does not remove it from your design or layout. In the first example below,
the tree shows the object "Equipment Reservation.1." In the second example
it has been removed from the tree but continues to show in the layout.
Changes made in the specifications
tree remain effective until you change them again.
