Now it’s time to create our B-Spline. From the main menu of Cinema 4D, go to Create | Spline | B-Spline. In order to start drawing your B-Spline, click somewhere in the viewport to create the first handle of your B-Spline. When we later attach our camera to this spline, the camera is attached to this initial handle. So care should be taken to select a good initial point for your B-Spline.
Click somewhere else to create your second handle. This will draw a line from first handle to second handle.
