merging layers

How do you merge layers in the animation timeline into one . Flatten options dont seem to work when i select a afew layers and click on it. I just need selcted layes to become one layer.


select everything from from the edit menu choose create drawing from selection. Then delete the old layers if you don’t want them anymore.

Another option if you want to keep the option of them in layers for editing while having them as one layer you can make them into a symbol.
