An editing device for three-dimensional shape data includes: a first setting part that sets at least one first characteristic point on three-dimensional shape data forming a three-dimensional shape; a second setting part that sets at least one second characteristic point on a predetermined distribution pattern, the at least one second characteristic point corresponding to the at least one first characteristic point set by the first setting part; and an assigning part that assigns an attribute to a three-dimensional range included in at least part of the three-dimensional shape in accordance with the distribution pattern so that the at least one first characteristic point set by the first setting part and the at least one second characteristic point set by the second setting part correspond to each other.
