To create the freestyle curves where you can put the point anywhere at any axis, use 3D curves at Shape -> Freestyle bundle menu. Offcourse you need to put the images of front, rear, top and left views in prior to get the dimension and geometry references. However, using the Freestyle Shape is not recommended to generate a surface, because it will not be a Class A surface that connects tangently perfect, thats why the tutor use the Generative Shape Design for better result of surfaces.
