If your design works are organized into different layers, you can try to lock the layer to avoid unintended modifications.
Lock layers to prevent changes
Locking a layer means you cannot make any changes to it – you can’t add, move, edit, stye or delete the shapes and connectors placed on that layer.
- When editing your design, you can go to View, Layers to bring up the layer window. Or you can press Ctrl+Shift+L / Cmd+Shift+L to display or hide the layers window.
- In the Layers window, click on the padlock icon to the left of the layer’s name that you want to lock.
Tips: You can lock a layer to avoid unintended modifications, or unlock it for editing.
See which layer an element belongs to
Select one element or a single group of elements. The little dot in the layer indicates your current selected element is in this layer.
Tips: This does not work when you select multiple shapes, as they may be on multiple layers.
