Understanding Bézier shapes

Before reshaping Bézier boxes and lines, make sure you understand the following definitions.

Point: A point connects line segments and defines where line segments start and end. Points connecting curved line segments have curve handles that control the shape of the curves. QuarkXPress offers three types of points: Corner, smooth, and symmetrical.

Corner point: A corner point connects two straight lines, a straight line and a curved line, or two noncontinuous curved lines. With curved lines, the corner point’s curve handles can be manipulated independently, usually to form a sharp transition between the two segments:

Smooth point: A smooth point connects two curved lines to form a continuous curve. The curve handles always rest on a straight line through the point, but they can be distanced independently:

Symmetrical point: A symmetrical point connects two curved lines to form a continuous curve. The result is similar to a smooth point, but the curve handles are always equidistant from the point:

Curve handles: Curve handles extend from either side of a point and control a curve’s shape:

Line segments: Line segments are straight or curved line sections positioned between two points:

When the Select Point tool is positioned over an active Bézier box or line, various pointers display indicating whether you can select a point, the curve handles, or a line segment. Click and drag using the pointers to reshape the Bézier box or line.

  • To change the shape entirely, choose a different option from the Item > Shape submenu.
  • To add a point to a Bézier box while working with the Bézier Pen tool QuarkXpress tool bezier Understanding Bézier shapes, click a line segment. Alternatively, you can use the Add Point tool QuarkXpress tool add point Understanding Bézier shapes.
  • To remove a point from a Bézier box while working with the Bézier Pen tool QuarkXpress tool bezier Understanding Bézier shapes, click the point. Alternatively, you can use the Remove Point tool QuarkXpress tool remove point Understanding Bézier shapes.
  • To convert a point to another type of point while working with the Bézier Pen tool QuarkXpress tool bezier Understanding Bézier shapes, Option+click/Alt+click the point. Alternatively, you can use the Convert Point tool QuarkXpress tool convert angle Understanding Bézier shapes.
  • To move a point or change the shape of a line segment while working with the Bézier Pen tool QuarkXpress tool bezier Understanding Bézier shapes, Command+drag/Ctrl+drag the point or line segment.
  • To select curves or points so that you can move them or delete them, use the Select Point tool QuarkXpress tool select Understanding Bézier shapes. Press Shift and click to select multiple points. Option+click/Alt+click a point to make it symmetrical.
