Abstract: A server includes an accessing means that accesses a database that stores 3D data sets for a plurality of objects. The 3D data sets include 3D modelling data and appendix data for each of the plurality of objects. The 3D modelling data also includes a plurality of elements. A receiving means receives an API request from an information processing device, the request including information that specifies an object, and an element to be used from among the plurality of elements. A transmitting means transmits to the information processing device, as an API response to the API request, data extracted from the database to output a 3D model of the object specified by the request information indicated by the 3D modelling data consisting of the specified element(s).

Abstract: The information processing device includes an obtaining means configured to obtain 3D modeling data that defines a 3D model of an object, an identifying unit configured to automatically identify an element to be edited among elements constituting the 3D modeling data based on appendix data corresponding to the 3D modeling data, and an editing means configured to automatically edit the identified element.

Abstract: A centrifugal water pump for use in a diesel engine cooling system provides an improved water pump construction including multiple features which combine to provide increased operating life for the supporting and wearing components of the pump. The improvements include one or more of: a water seal system is provided having a stationary seal and a rotating seal made of silicon carbide with at least one of the seals having embedded lubricant; an o-ring added to the stationary seal ensures that pressurized water does not get past the stationary seal; metallic bearing seals and covers to prevent leeching of the lubricant from the bearing; optimized spring force on the rotating seal; tapered shaft impeller interface to minimize torsional stresses on these components from the keyway design of the prior art; and the housing engine oil inlet is removed to prevent the direct flow of hot, dirty, and contaminated oil from damaging the water pump bearings.
