Select and Arrange Objects in Adobe Illustrator
In Adobe Illustrator there are selecting, stacking, and positioning objects precisely to layout and organize the artwork. We measure, align, and group objects to treat it as a single unit.
Selection options and preferences
We need to differentiate the object from the objects around it before we can modify an object. The selection tools and methods available in Illustrator are as follows:
Isolation mode: The isolation mode can be used to quickly isolate a layer, sublayer, group, or path of objects from different art in our document. All other materials will be dimmed until the selected segment is in isolation mode.
Layers panel: It can be used to select individual or multiple objects quickly and precisely.
Selection tool: The selection tool 
can be used to select the objects or group of objects by a click and dragging over them.
Direct Selection tool: The direct selection tool 
can be used to select path segments or individual anchor point.
Group Selection tool: 
It can be used to select the object inside a group or a group within multiple groups.
Perspective Selection tool:

Lasso tool: We can use Lasso tool 
to select anchor points, objects, or path segments.

can be used to select objects of the same color, stroke weight, etc.
Live Paint Selection tool: 
It can be used to select the faces and edges of the live paint group.

Layers in Adobe Illustrator can be used to manage all the obejcts that make up our artwork when we create any complex artwork. The structure of the layers can be simple or complex depending on the need. The document can be organised in single parent layer by default.
