Abstract: To provide a design assistance system, a design assistance program, and a design assistance method which are capable of reducing or eliminating the burden on a designer of a structure when designing the structure. A design assistance system 10 includes an object recognizing unit 112 and an interference determining unit 113. The object recognizing unit 112 recognizes an object existence area which is an existence area of a different object A2 from the structure A1 on a three-dimensional coordinate system in accordance with information including the position of the object A2 on the three-dimensional coordinate system which has been specified through an input unit 12. The interference determining unit 113 determines the presence or absence of interference between each of plurality of members and the object A2 based on respective member existence areas of the plurality of members and the object existence area.

Abstract: When a display part to be set as a similar part search target is selected from among a plurality of display parts displayed on a design screen, an operation of selecting an executing button for a single-part search is performed on a recommender execution selecting screen, and an operation of selecting a YES button is performed on a search execution confirmation screen. The model number of the one display part being selected is extracted, a server is accessed via the Internet, and similar part search data including the extracted model number is transmitted. A CPU of the server refers to similar part data stored in a memory, and retrieves similar part model numbers associated with the extracted model number. The part data of the extracted model number and the part data of all of the retrieved similar part model numbers are transmitted from the server to a user terminal.

Abstract: According to one embodiment, a three-dimensional data processing apparatus includes: an acquiring unit configured to acquire point group data measured by a three-dimensional measuring instrument that emits a beam for scanning from one position in a space in which a target object exists; a discriminating unit configured to discriminate a region unirradiated with the beam in the space on a basis of the point group data; a coordinate integrating unit configured to integrate, into one global coordinate system, respective local coordinate systems at a plurality of the positions at each of which the three-dimensional measuring instrument is placed; and an extracting unit configured to extract an overlapping region formed by integrating, into the global coordinate system, the unirradiated regions discriminated in the respective local coordinate systems.

Abstract: A three-dimensional data processing apparatus includes: a superposition unit configured to superpose obtained point group data and CAD data on a three-dimensional coordinates; a segment extraction unit configured to extract a segment of the point group data corresponding to each of a CAD parts which is constituent of the CAD data; and a segment operating unit configured to operate the segment in the three-dimensional coordinates.
