9. Group Elements
some FM commands, the user can use a “grouping” facility
to bundle multiple elements to be used as a target of some specific
operation, such as deletion, transformation, and so on. This grouping
is itself a temporary FM, to be activated during some permanent FM
operation. When grouping is allowed, Group icon is enabled. Once in
this mode, various grouping manipulations are available. Hitting Group
OK icon signals the target selection confirmation, and the user is
returned to the original permanent FM.
This icon is enabled if grouping is allowed. Clicking
this icon sets a temporary function mode for grouping elements. Select an element to be grouped.
A grouped element will be highlighted. Clicking an
already-selected element will remove it from the group. To facilitate grouping, the user can
use a “trap box” by R-clicking one corner of the trap box and then
R-clicking the other diagonal corner of the box. All the elements
within the trap box will be highlighted to show they are grouped. The
user can use this box trapping as many times as needed. An individual
selection of an element alters the grouping status: That is, an element
already in the group will be removed from the group, an element not in
the group will be placed in the group. TOGGLE alters the grouping
status of all elements all at once.
Key in a layer
number to include all elements with that layer value. To remove all
elements of the same layer value, just key in the negative value.
Click this icon to put all existing
elements in the group.
Click this icon to clear the group –
remove all elements out of the group.
Grouping is in lieu of selecting and
identifying target elements. When
grouping is satisfactorily accomplished, the user hits this button to
invoke the intended action at hand, such as deletion of the elements,
for instance. This Group OK icon is enabled only if the FM in effect
accepts grouped elements as a target.
