58 Lines, Curves, and Shapes
To extend a line:
1. Move the cursor over either of the end nodes, a small + cursor will
appear. Click at that location.
2. The line that you drag out will be a continuation of the existing line, as
a new line segment.
To draw a curved line:
1. Choose the Pen Tool from the Drawing toolbar.
2.
From the displayed context toolbar, choose to create your
drawn segments in Smooth joins or Sharp joins creation mode. By
default, you'll be in Smooth joins mode (i.e., drawing Bézier curves
segment-by-segment). Sharp joins would create a zig-zag line without
curving through nodes.
3. Click where you want the line to start (1).
4. Click again for a new node and drag out a pair of control handles
which orbit the node (2). (Control handles act like "magnets," pulling
the curve into shape. The distance between handles determines the
depth of the resulting curved line.) Release the mouse button to create
your curve segment (3).

5. To extend an existing line, click beyond the end of your current curve
to create a new node (thus creating another curve segment). Normally,
curve segments end in a symmetric (evenly rounded) corner (4), with
control handles locked together.
