Editing the shape of a B-spline curve

You can edit the shape of a B-spline curve by moving the control points.

1. Select the B-spline curve.

   

   The control points are displayed on the curve. Each point has a label.

   

2. Drag a control point to change the shape of the curve.

   In the example below, control point 4 is dragged upwards.

   

   When you drag the control points that are not at the end of the curve, the shape of the curve changes and some of its points move too.

   

Note: The end points always remain fixed, unless you drag them. If you drag an end point, only that point moves.

You can also move a selected control point using the Position dialog.

1. Click Curve Tools tab > Selection panel > Point to display the Select Point dialog.
2. Use the Select Point dialog to select a control point.
3. Click to display the Position dialog.
4. Use the Position dialog to move the selected control point.
