Using the Shape Builder Tool in Illustrator: Step by Step

Draw overlapping shapes and select them all with the Selection Tool (V).

2. Choose the tool

Press Shift+M or pick the Shape Builder tool from the Tools panel. Regions highlight as you hover.

3. Merge shapes

Click and drag across several regions to unite them into one shape.

4. Subtract shapes

Hold Option (Mac) or Alt (Windows) and click a region or drag across edges to delete it.

5. Split and refine

Click a single region to split it from the others. Use the Direct Selection Tool to refine corners and Pathfinder for fast Unite or Minus Front operations.

Tips for Better Results

• Double-click the tool to open options such as gap detection and fill color.
• Use it to build icons and logos from circles and rectangles.
• Use Pathfinder when you want exact boolean results on whole shapes.
• Group the result so it stays together.

Common Problems and Fixes

• Regions will not highlight: select all the shapes first.
