Concentric circles
The Concentric Circles tool draws nested rings of ovals or circles.
You can set the number and spacing of the rings before or after you
draw concentric circles.
To use the Concentric Circles tool
1
Select the Concentric Circles tool.
2
Drag to draw a bounding box that defines the size of the con-
centric circles object. A rectangular bounding box creates concen-
tric ovals; a square bounding box creates true circles.
3
When you finish, the concentric circles object is selected.
To draw true concentric circles: Press Shift to constrain the
bounding box to a square when you drag the Concentric Circles tool.
To draw from the center: Press Option (Mac) or Ctrl (Win-
dows) to draw from the center outward with the Concentric Circles
tool. Press Shift also to draw perfect circles outward from the center.
To edit concentric circles
You can change the number of rings of an existing object drawn with
the Concentric Circles tool.
1
Double-click the Concentric Circles object. The Concentric
Circles dialog box appears.
2
Adjust the settings as described in the next section. Click OK
to close the dialog box and apply the settings to the object.
To configure the Concentric Circles tool
Before you draw an object, you can double-click the Concentric Cir-
cles tool icon to open the Concentric Circles dialog box. Use the dia-
log box to configure the Concentric Circles tool before you draw
with it, or to change the configuration of an existing concentric cir-
cles object.
