The Shape Builder tool is a great way to create shapes in Illustrator. You can use it to create basic shapes, or you can use it to create more complex shapes. To use the Shape Builder tool, first open the toolbox and select the shape you want to create. Then, click on the blue arrow at the top of the toolbox and select the shape type you want to use. Next, click on the green arrow at the bottom of the toolbox and select the size of your desired shape. You can choose a small or large size for your shape. Once you have selected your shape, click on the blue arrow at the top of the toolbox and select one of Illustrator’s built-in features: perspective or perspective projection. If you choose perspective projection, then your shape will be projected onto its surrounding objects in a 3D space. If you choose perspective without projection, then your shape will be projected onto its surrounding objects in a 2D space.
