To draw a shape from Bezier curves:
Select the Bezier Curve Tool.
Click to create the first node and start drawing the first line segment.
Click again to complete the first line segment. This creates a second node and also starts drawing a second line segment. NOTE: A shape's outline always passes through all of its nodes.
Continue constructing your shape in this way by adding more line segments and clicking to add each new node.
To draw a shape with tight curves and frequent changes of direction, create more nodes that are closer together than when drawing a simpler shape.
To correct a mistake, press the Backspace key to delete the last line segment drawn. Press the Backspace key repeatedly to delete more than one line segment. Press the Escape key to delete all of the line segments and start drawing the shape again.
End drawing by double clicking. To draw a closed shape, end drawing sufficiently near to the first node to display the mouse text "Double-click to Close". This will join the last line segment to the first node.
You can adjust your shape in various ways using the Pointer, Reshaping and Rotation Tools.
