### Three Types of Nodes

CorelDraw has three types of nodes:

• A smooth node is used to create a seamless curve. The control points of a smooth node are always directly opposite each other. If you move a control point, the opposite control point moves, too. The distance between control points can vary (Figure 6.4). This means that the path on one side of a node can be curved differently than the path on the other side of the node.

##### Figure 6.4. The control points for a smooth node are locked into alignment, but the levers can be different lengths.

• A symmetrical node is similar to a smooth node. Its control points are always opposite each other; if you move a control point, the opposite control point moves, too. What's different is that the control points are always the same distance from each other (Figure 6.5). This results in an even shape on both sides of the node.

##### Figure 6.5. The control points for a symmetrical node are also locked into alignment, but the levers are the same length.

• A cusp node is used to create sharp corners on a path. The cusp node's control points move independently of each other; thus, a curve that passes through a cusp node can bend at a sharp angle (Figure 6.6).
