Or, there may be only one handle which controls a curve on one side of the anchor. The shape has an angle or corner at that anchor instead of a smooth curve through it. In the Disconnected method, each handle is independent of the other. However, they are not the same distance from the vector point so the curve tapers off more quickly on one side. If both handles are at the same angle, there’s no visible corner or point in the contour.Īs in the Mirrored method, in the Asymmetric method the handles are at the same angle. The handles align to form a single line tangent to the curve. It involves two handles that extend the same distance from the vector point, at the same angle. Mirrored is the default and most common method. There are three methods for controlling a Bézier curve: Mirrored, Asymmetric, and Disconnected. A line segment with Bézier points at both its endpoints has two handles that control its shape. Each anchor point has two handles, one corresponding to the line on either side of the anchor. Handles control the curve of the line and its direction. With a little knowledge and some practice, you can understand how moving a Bézier point changes the contour of a curve.īézier curves in Keynote have two parts: Anchors and Handles. They are differentiated by how the curve is controlled and the complexity with which it is drawn. There are different types of Bézier curves. They are used in typeface design because the paths can be scaled infinitely. Bézier curves were quickly adopted in computer graphics because they work well for drawing. In the 1960s he used them to design Renault cars.

Which gives you some idea of how subtle and complex curves can be.

The Bézier curve is named after Pierre Bézier, an engineer with degrees in mechanical and electrical engineering, plus a doctorate in math. The third type, Bézier, is more powerful but less intuitive to use so it helps to understand how they work. Manipulating them is intuitive enough for you to learn by doing. The first two types of points are easy to understand. This may seem innocuous and convenient, but most of the time it’s not. If it checked, when a line in a shape is clicked and a new point is formed, it is a Bézier point.

In the Keynote Preferences panel, uncheck General > Editing: Curves default to Bézier.

That is, a point that was a Smooth point that is then changed into a Bézier point may behave differently than if the point started out as a Bézier point.

A curve may be affected by what type of point a point was previously.

Simple lines and arcs are easier for a viewer to read than complex curves so be sure the complexity is needed. Bézier points should only be used if more complex or subtle curves are needed.

Rely mostly on Sharp and Smooth points.

Then, points can be set to Smooth or Bézier as needed. This makes it easy to block in the overall area of the shape.

When making a shape not based on an existing shape, it’s usually best to use Sharp points.

The fewer the points in a shape, the easier it is to understand how each point affects the contours of the shape. If you’re nervous about it, make a copy of the shape first.

If you have trouble getting the shape you want, remove points.

To change the type of a point, right click on it and select Sharp, Smooth, or Bézier.

Change them to Smooth or Bézier points as needed.

Unless you already know what kind of curve you need, start with Sharp points.

The simpler the shape, the easier it is to change.

If you strategically place vector points along a curve, you can reduce the amount of points in the shape which makes it a simpler.

Here’s some suggestions about how to use them: If you instead place a Bézier point on the line, you can create a more complex curve. If you place a Smooth point on that line, you can create an arc. A line between two Sharp points has no curves in it. Each type of point affects the line in a different way. The type of a point affects the line its on.
