Controlling Layer Appearance
Suppose you need to create a series of objects that all have the same type of drop shadow or some other effect. Instead of applying the effect to each object, you can apply effects and other appearance attributes to an entire layer or sublayer. This approach can be a great way to keep the effect options consistent on each object, and any new object added to the layer or sublayer will have the effect applied automatically. Here's how you do it:
- Create a layer or sublayer; then create a series of objects on it.
- Click the target button to select it. The target button is in the Target column to the right of the sublayer or layer name in the Layers panel (see Figure 7).
- To apply an effect, open the Effect menu or click the Add New Effect button at the bottom of the Appearance panel, and select the desired effect. Notice that the effect is applied to all objects on the layer (that is, wherever it can be applied).
This technique also works if you drag-and-drop content from one Illustrator document into another.
