You can use a pattern as a layer’s fill or stroke. The pattern’s source references another object on the canvas in the same file. This could be a single layer, or multiple layers in a group or frame.

Change a layer’s fill or stroke to a pattern

1. Select a layer on the canvas.
2. Click the swatch in the Fill section of the right sidebar to open the color picker.
3. Select Pattern from the fill options.
4. Click Select source, then select another object on the canvas.
5. Use the pattern options to set the tile type, scale, spacing, alignment, and opacity.

Pattern fills are dynamic. If you update the pattern’s source object, the pattern will automatically update on each layer where its used.
