1. Have a current object selected.
2. Choose the “Assign a Path” command in the Animation menu.
OR Toggle the current tool palette by pressing the spacebar or selecting Render & Animation in the Toolbars menu and click on the Animation Path Icon.
3. If you already have a curve drawn in your scene, you can click on it to select it as the desired path.
If you want to draw the path of the object by hand, click on the object itself. You are now in the Bezier curve construction tool. Build the curve and leave the tool as usual.
The selected curve or the drawn curve is now assigned as the animation path of the currently selected object.
Two things will happen:
¨ The current object will be snapped to the first point of the curve (first frame of the animation path).
¨ The curve will be subdivided so its number of points will be the number of desired animation frames (50 by default).
