To create a shape using the Shape Builder tool, do the following:

  1. Create the shapes on which you want to apply the Shape Builder tool.

  2. Using the Selection tool, select the paths that you need to merge to create the shape.

    Note:

    Make sure that you select only those paths on which you need to apply the tool. If you select all the paths before merging, then there would be a performance overhead.

  3. Select the Shape Builder tool from the Tools panel or press Shift+M. By default, the tool is in merge mode, where you can combine different paths. The pointer in this mode appears as .

  4. Identify the region that you want to extract or merge.

  5. To break or extract the region from the rest of the shape, move the pointer and click the selected region.

    Additional anchor points are introduced where the shapes break up.

  6. To merge paths, drag along the region and release the mouse, the two regions get merged to form a new shape.

    The art style that the new shape inherits, depends on the following rules:

    • The art style of the object from where the mouse drag was initiated is applied to the merging shapes.

    • If no art style is available on mouse down, then the art style available on mouse release is applied to the merging shapes.

    • If no art style is available on mouse down or mouse release, then the art style of the topmost selected object in the Layers panel, is applied.

    For coloring, you can override these rules by selecting Color Swatches from the Pick Color From drop-down list in the Shape Builder Tool Options dialog box. For details, see Setting the Shape Builder tool options.

    Pressing Shift+click+drag displays a rectangular marquee, which allows you to easily merge multiple paths.

  7. To use the Erase mode of the Shape Builder tool, press the Alt key (Windows) or the Option key (Mac OS) and click the closed region that you want to delete. When you press the Alt key (Windows) or Option key (Mac OS), the pointer changes to .

    In Erase mode, you can delete regions within selected shapes. If you delete a region that is shared by multiple objects, the shapes are broken in such a way that the regions selected by the marquee are removed from the shapes.

    You can also delete edges in erase mode. This option is useful when you want to clear the remaining portions after creating the required shape.
