When drawing with the Pen tool in Adobe Illustrator, it's easy to create beautifully curved lines that are connected to fixed points. These are known as Bézier curves, and they're named after Pierre Bézier, a French engineer who helped to establish the field of geometric modeling. Bézier decided to patent his iconic curve, and today, the Bézier curve is used in most graphic design applications. Below, we've shared how to create a Bézier curve in Illustrator, adjust the curve using anchor points and control handles, and combine multiple curves into a complex shape.
Drawing a Bézier Curve
In most cases, you'll be drawing bézier curves using the Pen tool, which is truly one of the most versatile tools in Illustrator. Unlike the Line tool, the lines you create with the Pen are called paths, and they're created with an anchor point on each side. These points look like tiny squares, and they allow you to transform a straight line into a dramatic curve.
Adding and Deleting Anchor Points
The designers at Adobe have made it easy to edit your designs, all with the same Pen tool. You may have noticed that the Pen cursor changes when you move it over certain objects. If you place the Pen on a path, it turns into the Add Anchor Point tool, and if it's on an anchor point, it turns into the Delete Anchor Point tool. After that, all you have to do is click.
