Consolidate layers and groups

Merging and flattening layers are similar in that they both let you consolidate objects, groups, and sublayers into a single layer or group. With merging, you can select which items you want to consolidate; with flattening, all visible items in the artwork are consolidated in a single layer. With either option, the stacking order of the artwork remains the same, but other layer-level attributes, such as clipping masks, aren’t preserved.

  • To merge items into a single layer or group, hold down Ctrl (Windows) or Command (Mac OS) and click the names of the layers or groups that you want to merge. Alternatively, hold down Shift to select all listings in between the layer or group names you click. Then, select Merge Selected from the Layers panel menu. Note that items will be merged into the layer or group that you selected last.

    Layers can only merge with other layers that are on the same hierarchical level in the Layers panel. Likewise, sublayers can only merge with other sublayers that are within the same layer and at the same hierarchical level. Objects can’t be merged with other objects.

  • To flatten layers, click the name of the layer into which you want to consolidate the artwork. Then select Flatten Artwork from the Layers panel menu.
