Rotational sweep is one of the types of sweep representation. It defined by rotating a planar curve (generator) around an axis line. So, this is coding how sweeping representation present the outer surface of a bottle water. There are two attachments which is the generator.m is for the generator curve and the sweepsurface.m is for the swept surface.
