In order to create an animated path, you must first create the curve that is used to derive the animation.

To create a 3D curve:

1. Double-click 3D Curve in the Asset browser’s Elements folder. The cursor becomes a cross hair.
   

   Asset browser A. 3D Curve asset

2. Click anywhere in the Viewer window to set red points that are connected by a green line. This line is a 3D curve.

   Use the middle mouse button to create a point between the last two points, or click the right mouse button to add a point at the start point.

3. To accept the curve, press Enter. To undo a point, press Ctrl-Z. To delete the entire path, press Escape.
