Selection R egion flyout
The Selection Region flyout provides access to five
methods you can use to select objects by region.
Clicking the Selection Region button displays
a flyout containing the
Rectangle (page 1–80) ,
Circular (page 1–81) , Fence (page 1–81) , Lasso
(page 1–82)
,and Paint (page 1–82) Selection
Region buttons.
For the first four methods, you can select either
objects that are completely w ithin the selection
region (window method), or objects that are
w ithin or touched by the selec tion shape (crossing
method). Toggle between the window and crossing
selection methods by using the
Window/Crossing
Selection button (page 1–88)
on the Main toolbar.
Note: If you hold down CTRL while specifying
a region, the affected objects are added to the
current selection. Conversely, if you hold down
ALT while specifying a region, the affected objects
areremovedfromthecurrentselection.
Procedure
To s elect using a r egion (gener al met hod):
1.
Choose a Selection Region method from the
flyout.
2. Drag in a viewport, then release the mouse.
The first location you click is one corner of the
rectangle, and where you release the mouse is
theoppositecorner.
Impor tant: If you’re using Select Object (page 1–77) ,
you can start dragging anywhere to select a region:
on an object or off. However, if you’re using one of
the transform tools, such as
Select and Move (page
1–419)
, start the drag operation away from an object;
that is, in an empt y part of the viewport. Otherwise,
if you start dragging on an object, m ost likely the
software will assume you intend to select where
you click and will begin the transform operation
immediately.
To cancel the selection, right-click before you
release the mouse.
