Adjusting curves

A curved line segment consists of two data points (end points) and two control points (handles). A control line connects a control point to a data point. You can change the shape of a curve by converting a data point to a different type, or by dragging the control points to a different location.

The data points are represented by squares and the control points by circles. A control point might overlay a data point.
  1. Make sure toolbar is displayed. Click View > Toolbar > Bézier.
  2. Select a curved line, and then click the Edit Points icon to display the data and control points.
  3. Do one of the following:
    • Drag a data point to resize the line. If a control point overlies the data point, drag the control point until you can see the data pilot, and then drag the data point.
    • Drag a control point. The curve pulls in the direction that you drag the control point.
    • Click the Smooth Transition, Symmetric Transition, or Corner Point icon to change the type of the data point.
  4. Optional: You can only split a curved line that has three or more data points. To split a curved line:
    1. Select a curved line, and then click the Edit Points icon on the toolbar.
    2. Select a data point, and then click the Split Curve icon on the toolbar.
  5. Optional: To create a closed shape:
    1. Select a curved line, and then click the Edit Points icon on the toolbar.
    2. Click the Close Bézier icon.
