You can see how each wheel turns at a constant rate, and how this affects the drawing point. The resulting line is idential to the line drawn with animation turned off. When animation is on, Spiro pauses briefly between each step to slow down the drawing and let you see better what is happening. The Status Line Below the Animate button is the status line. Advanced Commands Pressing the Advanced button in the main window brings up the Advanced window.
Additional commands appear at the top of that window.
Add Wheel Adds an additional wheel to the main window. The additional wheel lets you make even more complicated patterns. If the layout of your main window is now not quite right, resize it slightly to force it to relayout. After you have added wheels and decided you have too many, this command removes a wheel from the main window. As with the Add Wheel command, if your main window layout is not correct, resize it slightly.
