In Blender 2.7 or 2.8 how can you slice off parts of a 2D grease pencil drawing and move it to its own layer? Basically, I am trying to create something like this https://youtu.be/nEM_oY-RZjg. I have downloaded that file and noticed that each body part is on a separate layer. The issue is when I draw a face I never would draw a body part, create a new layer and then draw another body part. so I would like to draw my entire character first then slice it in blender to make sure the eyes, nose, mouth are on its separate layers so I can then add a parent bone and make a rig out of it. How can I do that?



If I use the 2d monkey from 2.8 as an example I would like to slice off that on its own layer so I can add bones to it to make a 2d eye rig. Unless there is a better way.
Begin editing the GP strokes. In 2.80 you select the GP objects and go into edit mode, while in 2.79 you need to select Edit Strokes in the mode menu.
Select the curve points that you want to move to another layer.
Press M and either choose an existing layer or New Layer.
