Main toolbar > Lasso Selection Region (Selection Region flyout)

The Lasso Selection method lets you select multiple objects within a complex or irregular region with a single mouse action.

The Lasso Selection Region button, available from the Selection Region flyout, provides one of five methods you can use to select objects by region. The other methods are Rectangular, Circular, Fence, and Paint.

You can use Lasso 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 button 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.
