The Shape Builder tool lets you create new shapes by combining or subtracting vector shapes. Instead of editing paths manually, you can drag across regions to merge them or remove unwanted sections.
Select two or more vector shapes.
Click the **Shape Builder** tool from the **Create Tools** menu in the Toolbar or press **Shift** + **M**.
Drag across adjacent regions to merge them into a single shape.
Hold Alt (Windows) or Option (macOS) while dragging or clicking to remove regions from the shape.
