Merge paths using the Blob Brush tool

Last updated on Sep 11, 2025

Learn how to merge paths using the Blob Brush tool.

Use the Blob Brush tool to paint filled shapes that intersect and merge with other shapes of the same color.

Select the path into which you want to merge a new path using the Selection tool.

Select Window > Appearance.

In the Appearance panel, select More options . Then, deselect New Art Has Basic Appearance.

Tip

This ensures that new artwork created with the Blob Brush tool inherits the appearance of the selected path.

Select the Blob Brush tool and ensure that it uses the same appearance as the selected artwork.

Draw paths that intersect with the artwork.

Note

If paths do not merge, ensure the Blob Brush tool attributes match the existing path attributes and neither uses a Stroke.
