Inter face
The dialog window lists all named selections at
the current sub-object level. The buttons b e neath
the windows let you delete, merge, and edit the
listed items. Use standard m ouse-plus-keyboard
methods(usingCTRLorSHIFT)tohighlight
list items and designate them for subsequent
operations.
To rename a set, click it in the list, and then edit its
name in the one-line window immediately below
the list.
Co mbine—Merges all objects f rom the highlighted
selection sets into a single, new selection set. Select
two or more selec tion sets, a nd then click Combine
and enter a new name for the selection set. Use
Delete to delete the original sets.
Delete—Deletes all highlighted items from the
Named Selections window. This affects only
selection sets, not the sub-objects they refer to.
Subtract(A-B)—Removes the sub-objects contained
in one selection set from another. Select one
item in the N amed Selections window, and then
select the other. The top highlighted item in the
window is operand A, and the bottom is operand
B (regardless of the order of their selection). Click
Subtract (A-B) to subtract the sub-objects in the
bottom item from those in the top item. There
must be some overlap between the two selection
sets for this command to have any effect.
Subtra ct (B -A)—Subtracts the sub-objects in the
top selected item from those in the bottom item.
Intersection—Creates a selection set that consists
only of sub-objects that all highlighted selection
sets have in common. Highlight two or more items
in the Named Selections window, and then click
Intersect ion. In the dialog that appears, enter a
new set name and click OK.
