Title: THREE-DIMENSIONAL PRINTING SYSTEM AND INFORMATION PROCESSING APPARATUS
Abstract: A three-dimensional modeling system (1) includes a three-dimensional modeling apparatus (3) that models a three-dimensional object, and an information processing apparatus (2) that transmits information about a three-dimensional object to be modeled to the three-dimensional modeling apparatus (3). The information processing apparatus (2) includes modeling data generating means (203) for generating modeling data based on three-dimensional object shape data (31) representing a three-dimensional shape of a predetermined three-dimensional object and based on streamline shape data (32) of a streamline representing fluid flow around the predetermined three-dimensional object, the modeling data being for modeling, by the three-dimensional modeling apparatus (3), a three-dimensional object including the predetermined three-dimensional object and the streamline, and data transmitting means (204) for transmitting the modeling data to the three-dimensional modeling apparatus (3), the modeling data being generated by the modeling data generating means (203).

text: The three-dimensional modeling system (1) according to claim 1, characterized in that 
the modeling data generating means (203) generates at least one piece of support plane data of a support plane, the support plane being capable of supporting both the predetermined three-dimensional object and the streamline.
number: 5
text: The three-dimensional modeling system (1) according to claim 1, characterized in that 
the support plane data is data on a plane, the plane being substantially perpendicular to a direction of the fluid flow of the predetermined three-dimensional object, and having a certain thickness.
number: 6
text: The three-dimensional modeling system (1) according to claim 1, characterized in that 
when the streamline comprises a plurality of streamlines, the modeling data generating means (203) generates modeling data for modeling one of the plurality of streamlines with a different color than a color of another streamline.
