Aim: What is a Bezier curve?

Pierre Bezier The anchor points can define a curve’s attributes. The curves are known as Bezier Curves. They are named

after the French mathematician Pierre Bezier, who developed a method for defining curves automatically.

Rules About Bezier Curves1. The length and angle of the handles “anticipate” the curves that follow.2. To ensure that the curve is smooth, place anchor points on either side of an arc, not in between.3. The fewer the anchor points, the smoother the curve will look and the faster it will print.4. Adjust a curve’s height and angle by dragging the direction points, or grab the curve itself to adjust the height.

Ways to Hinge Bezier CurvesAs You Draw

1. While you are click-dragging to draw a curve, press the Alt key to hinge the curve - pulling the

handle in a new direction.
