Creating a Perfect Circle

  1. Accessing the Ellipse Tool: Navigate to the Rectangle Tool, click and hold to reveal a dropdown, and select the Ellipse Tool. The shortcut key for this tool is ‘L’.
  2. Drawing the Circle: Click and drag to start drawing an oval. To ensure it’s a perfect circle, hold the ‘Shift’ key while dragging.
  3. Filling and Stroking: Once the circle is drawn, you can fill it with a color using the ‘Fill’ option. Additionally, you can add an external path or stroke, adjust its color, and increase its size for visibility.

Crafting a Half Circle

  1. Using the Rectangle Tool: With the Rectangle Tool, draw a rectangle that covers half of the circle. Ensure it aligns perfectly with the circle’s center.
  2. Shape Builder Tool: Select both the circle and the rectangle. Then, access the Shape Builder Tool (shortcut: Shift+M). This tool identifies overlapping areas.
  3. Subtracting the Rectangle: Hold ‘Option’ (or ‘Alt’ on PC) and click and drag through the overlapping areas. This action will remove the rectangle’s portion, leaving behind a half circle.

Designing a Quarter Circle

  1. Drawing Another Rectangle: Press ‘M’ to access the Rectangle Tool and draw another rectangle, this time covering half of the half circle.
  2. Selection and Shape Builder: Press ‘V’ to use the Selection Tool and select both shapes. Use the Shape Builder Tool (Shift+M) again.
  3. Subtraction for the Quarter Circle: Just like before, hold ‘Option’ or ‘Alt’ and click and drag through the overlapping areas. This will leave you with a quarter circle.

Conclusion

Creating circles and their segments in Illustrator is a straightforward process. With the right tools, such as the Ellipse and Shape Builder, you can craft these shapes with ease and precision.
