Using node types

You can change the nodes on a curve object to one of three types: cusp, smooth, and symmetrical. The control handles of each node type behave differently.

Cusp nodes let you create sharp transitions, such as corners or sharp angles, in a curve object. You can move the control handles in a cusp node independently of one another, changing only the line on one side of the node.

With smooth nodes, the lines passing through the node take on the shape of a curve, producing smooth transitions between line segments. The control handles of a smooth node are always directly opposite one another, but they may be at different distances from the node.

Symmetrical nodes are similar to smooth nodes. They create a smooth transition between line segments, but they also let you give lines on both sides of a node the same curve appearance. The control handles of symmetrical nodes are directly opposite each other and at an equal distance from the node.

Each node type appears with a different shape - smooth nodes as circles, cusp nodes as squares, and symmetrical nodes as diamonds.

You can also change an existing node from one type to another by using shortcut keys. To change a smooth node to a cusp node or a cusp node to a smooth node, click the node using the Shape tool, and press C. To change a symmetrical node to a smooth node or a smooth node to a symmetrical node, click the node with the Shape tool, and press S.
