Using the Bézier tool in CorelDRAW® 12

In CorelDRAW 12, a Bézier line is a line made up of straight or curved segments, or both. The line segments are connected by nodes, which are depicted as square points. Each node has control points that allow the shape of the line to be modified.

 Each node in a Bézier line is depicted by a square point.

The Bézier tool gives you incredible control, allowing you to draw a line one segment at a time and to manipulate the line using its nodes.

                                The Bézier tool is located in the Curve flyout

To draw a Bézier line, click to place its first node, and then do one of the following:
  • Click where you want to end a straight line segment.
  • Click where you want to end a curved line segment, and then drag to draw the curve itself. Hold Ctrl as you drag to constrain the curve to 15-degree angles, or hold Alt to move the node before you actually drop it.
Add as many line segments as you want, and then press the Spacebar (or click the Pick tool) to end the line. To create a closed shape instead, click the first node you placed.

When you draw a line by using the Bézier tool, the pointer changes when you point to the first node you placed, indicating that you can create a closed object.

The Bézier tool shares a property bar with the Shape tool. Using the Shape tool, you can edit your Bézier line by doing any of the following:
  • Add or delete nodes.
  • Join two nodes, or break the line apart.
  • Convert a curve to a line or a line to a curve.
  • Make a node cusped, smooth, or symmetrical.
  • Reverse curve direction.
  • Extend a curve to close it.
  • Extract a subpath.
  • Auto-close a curve.
  • Stretch, scale, rotate, or skew a node.
  • Align nodes.
  • Enable the Elastic mode.
  • Select all nodes.

The available tools on the Bézier/Shape property bar change, depending on the type of node you select.
The Bézier/Shape property bar also has a new feature that lets you reflect nodes. To create intricate symmetrical lines, draw a Bézier line, and flip a duplicate of it. By selecting nodes from both lines, you can then use the Reflect nodes horizontally button or Reflect nodes vertically button on the property bar to mirror changes across their left and right side, or top and bottom.

You can create symmetrical Bézier lines by reflecting nodes.
Many handy Bézier tool features are also available by using the Shape tool and right-clicking a node in a Bézier line.

Finally, to customize the Bézier tool's settings, double-click the Bézier tool in the toolbox. The Freehand/Bezier tool page of the Options dialog box appears, allowing you to specify your own settings for the Bézier tool.
