If an object has been selected, clicking on it a second time (while holding down the
S
HIFT
key) will remove it
from the Select List).
Objects can also be selected by extent. To select objects by this method, click on a starting location, then
press and hold the left mouse button until the resulting box encloses all of the objects to be selected. When
the mouse button is released, all the objects totally within the extent of the box are selected.
To deselect all objects, click on the Select arrow button in the Shape toolbar, or position the pointer on an
empty area of the Working View and click the right mouse button.
4.2.6.3 Grouping and Ungrouping Objects
A group of objects and/or submodels can be configured so that they are all affected by the same opera-
tions (e.g., Move, Delete) or expressions

. (Grouping should be done prior to selecting the Dynamic
Attributes item, described in
sub-section.) Holding the
S
HIFT
key down, click on all
objects that are to be grouped; the number of objects which have been selected is shown by the Sel indi-
cator in the status bar. When all objects to be grouped have been selected, click on the
Group button
on the View toolbar.
A group can be changed back to a collection of individual objects. Click on the group to select it, then click
on the Ungroup button
on the View toolbar to remove all objects from the group. Any dynamics
attached to the group via the Dynamic Attributes entry will be deleted.
4.2.6.4 Depth and Grouped Objects
A collection of objects can be saved as a group. This group in turn can become part of another group, and
so on. The use of groups within groups gives rise to the concept of depth.
The Select Deeper button
on the View toolbar permits selection of objects within a Group. Each
time this button is clicked on, the Depth= indicator in the status bar is incremented by one. This number
indicates how deep within Groups an object can be selected. The default level is 0. A level of 1 permits
selecting objects within Groups, a level of 2 allows selecting an object which is inside of a Group which is
inside of another Group, and so on.
To reset the depth to the default of 0, click on the Select arrow button in the Shape toolbar, or position the
pointer on an empty area of the Working View and click the right mouse button.
4.2.6.5 The Extent of an Object
The extent of an object, also known as an extent rectangle, is the smallest rectangle, with a horizontal
base, which completely encloses all parts of an object. The extent of an object is used to determine the
location of the object's center; thus the center of any object is also the center of the object's extent.
