Description: A Freehand object is a Spline or Multiline that you create by freeform drawing.
Creation: Click on the Freehand tool. Click where you want the line to start and drag to create a line that follows your mouse movements. To end the line, release the mouse button.
The Freehand object is automatically smoothed into a Spline when you release the mouse button.
To control the amount of smoothing, set the slider in the Object pane of the Preferences window.
