All Blender versions – from the oldest to the current:
Creating thin long objects like pipes and wires is the often task in the interior, scientific of fantastic scenes. One of the easiest and most convenient ways to create such objects is using curves.
The main curves advantage is the easiest control and editing: any time you can change the shape of the curve, move its points, add new and delete unnecessary ones. You do not have to work with a lot of mesh points, but only with several points of the curve, which is much more convenient. Preprocessing for rendering scene with curves is also performed faster than with meshes.
