Selecting and Arranging Objects
Lock an Object
You can lock an object to prevent it from moving or being edited. In fact, locking prevents the object from being selected. As a consequence, you won't be able to modify it by mistake.
To lock an object, select it and tap on the Lock icon in the Layers panel.
It is possible to lock not only an individual object but a group or layer.
To unlock an object, tap on its Lock icon in the Layers panel.
