A shape layer is simply a layer that contains a vector graphic called a shape. To create a shape layer, draw a shape directly in the Composition panel, using any of the drawing tools or the Pen tool.
To duplicate a layer, select it, and choose Edit > Duplicate, or press Ctrl+D (Windows or Command+D (macOS). All the original layer’s properties, keyframes, and other attributes are included in the new layer.
To snap one layer to another in the Composition panel, select Snapping in the options section of the Tools panel. Then click next to the handle or point you want to use as a snapping feature, and drag the layer close to the point to which you want to align it. After Effects highlights the points to which it will align when you release the mouse button.
Pucker & Bloat pulls the vertices of a path outward while curving the segments inward (puckering), or pulls the vertices inward while curving the segments outward (bloating). You can animate the degree of pucker or bloat over time.
