1. It helps objects to be altered, grouped, hidden and moved as the designer wishes.
2. Layers can be grouped and worked on separated and common properties like color and line weight assigned to them.
3. Layers can be manipulated as the user wishes. They can be locked, frozen, turned off, etc. Locking prevents accidental changes being made on objects.
