Drawing and editing vector objects : Drawing curves
 
Drawing curves
You can draw Bézier and freehand curves.
To draw an object with Bézier curves
Edit workspace 
1 On the Tools toolbar, choose the Pen tool .
Note: If you want to place the line segment on the current vector layer, mark the Create on Vector check box on the Tool Options palette. If no vector layer exists, marking this check box creates one for the line segment. If this check box is unmarked, the line segment is placed on a raster layer. Placing a line segment on a vector layer makes it easier to edit.
2 On the Materials palette, click the Foreground and Stroke properties box, and choose a color for the outline.
If you want to apply a fill to the curve, click the Background and Fill properties box, and choose a color. If you do not want to apply a fill to the curve, click the Transparent button .
3 In the Tool Options palette, click the Draw Point to Point button .
4 Mark the Show Nodes check box.
5 Click where you want to place the first node, and drag.
As you drag, the arrow-end of the control arm handle points in the same direction. Release the mouse button when the first control arm reaches the desired length.
6 Click where you want to place the second node, and drag.
As you drag, the curve segment appears on the image canvas.
Note: If you marked the Connect Segments option, you can continue adding segments in this manner.
7 On the Tool Options palette, click one of the following buttons to complete the Bézier curve object:
Start New Contour button — creates an open shape where the first and last segments are not connected
Close Selected Open Contours button — creates a closed shape where the first and last segments are connected
8 Click the Apply button .
