The Layers Panel in Illustrator–Tips and Tricks

In my last post, I mentioned that the Layers panel serves a more vital function in Photoshop than it does in Illustrator. No offense to Illustrator, of course! But there is a reason I said this.

In Illustrator, unless the user makes it happen, objects cannot “smear” together as if they were oil paint that doesn’t dry. So the need to separate things by layer for Photoshop-ish reasons does not exist. But the Layers panel in Illustrator does serve another, equally useful, function—that of organizer.

Doc and Layers Panel

In fact, there are two levels of organization we can see in a typical Illustrator document:

First, the layers themselves, which can be used to keep things together in the same fashion as having two or three storeys in a house. A real-life example might be a document intended for publication in Canada, which requires many documents, especially legal ones, to be bilingual. If one places all the graphics in one layer, all the French text in a second, and all the English in a third, one can easily show or hide the appropriate text for printing two versions of the document, and avoid having to create two separate documents, which would take rather more space.

Basic Layers

Second, within each layer, there can be objects whose “stacking order” (in which one object is above or below another) determines what we see or don’t see of each object. The layers’ stacking order can be changed by simply dragging any layer up or down within the Layers panel. Ditto the objects within each layer. So one might describe the Layers panel as a stack of stacks.

Layers and Stacking Order

The only downside to this story is that it can get a little complicated, especially when one has grouped objects within the layers. Groups, however, show themselves by indenting the objects within the group, and having twist/folding arrows to open or close the group, allowing objects within the group to be moved up and down within them.

But one point remains the same between Illustrator and Photoshop: Don’t create more layers than you need, for whatever reason. Each layer is almost a separate document within the file, and takes up a significant amount of room, so be sparing.
