Digitize circles and ovals, squares and rectangles with a few clicks. With the addition of a third reference point, the Circle tool can create oval shapes. If you only want a perfect circle, press Enter twice. You can use any fill stitch type. When in doubt, follow the prompts in the Status Bar.
When using the Rectangle / Square tool, you only require two points. To create a perfect square, hold down Ctrl as you drag the pointer.
