Circular Selection Region

Selects objects within a circular area.

Main Toolbar > (Circular Selection Region), on the Selection Region flyout

You can use Circular to select either objects that are completely within the selection region (window method), or objects that are either within or touched by the selection shape (crossing method). Toggle between the window and crossing selection methods by using the Window/Crossing toggle 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 are removed from the current selection.
