Yes, the "Extract Surface" filter's name is a little misleading. What it really
does is convert a dataset from an unstructured grid (which may contain
volumetric elements) to a polydata (which may only contain 0-, 1-, or 2-d
primitives). In the process, any volume elements are represented by the
portions of their bounding surface not shared with other volume elements.
The Tube filter only runs on polydata. So it is not exactly extracting the
surface of a line so much as converting representations.
