How do I make layers invisible?
Just like objects, layers can be manipulated as well. However is this used for making designing easier and not for designing itself.
When you worked on a piece of the design, but it's interferring with the rest of the workspace. You can make layer invisible.
When you select a layer in the layer pane, a lock and eye will appear. When you click the eye (it will close) the layer is made hidden. You can also do this by right-clicking the object and select "Show/Hide."
To show the layer, click the eye again (it will open) or right-click and select "Show/Hide."
