Description

[Technical field]

[0001] The present invention relates to a data conversion device and a program for heterogeneous model linkage. [Background technology]

[0002] In architectural design, the layout of the building (architecture) is decided while taking into consideration the site conditions and the surrounding environment, and the design of the interior and exterior, floor plan, decoration, etc. is carried out first. In this design, 2D drawings as well as 3D drawings including perspective drawings are created using commonly used CAD (Computer-Aided Design). After this design, the structural design is carried out to set the columns and beams that make up the main frame of the building so that it meets safety requirements against snowfall, earthquakes, etc. Furthermore, after this structural design, production design is carried out to create a production model in which each component that will actually be used and produced in the factory is reflected in the model.

[0003] Recently, in the design of the above-mentioned buildings, information about buildings is shared among designers and engineers using a BIM (Building Information Modeling) model. Here, a BIM model is a three-dimensional model that has information about the shape in a virtual three-dimensional space of the components (also called objects, including beams, columns, walls, etc.) that make up a building, as well as information about the materials, dimensions, placement positions, etc. (collectively referred to as "specification information"). Using this BIM model, it is possible to create three-dimensional drawings of the three-dimensional model viewed from various angles, as well as to cut the three-dimensional drawings in various ways and create two-dimensional drawings such as floor plans (including floor plans) and elevation drawings (including framework drawings) viewed from various angles. In other words, each component that makes up a three-dimensional model contains various specification information, and this specification information can be changed, modified, or added, and a history of changes, additions, etc. can also be kept.

[0004] Incidentally, among the buildings to be designed, buildings in which the construction of the framework, roof, exterior walls, etc. is standardized, and the production process of the components is systemized, are generally referred to as "system buildings." For example, factories, logistics warehouses, and retail stores such as drugstores and convenience stores are given as examples of system buildings.

[0005] Here, an information management system using the above-mentioned BIM has been proposed. Specifically, it is an information management system having an information processing terminal used by a user and a server device communicably connected to the information processing terminal via a network. The server device is provided with a storage unit that stores shape information and specification information of an object in association with the object, stores work information in which the object is associated with a work item related to the object, and resource information in which the work item is associated with a resource item related to the object, a control unit that acquires information requested by a user using the information processing terminal based on the shape information, specification information, work information, and resource information, and a communication unit that transmits the acquired information requested by the user to the information processing terminal that is the request source. In addition, the information processing terminal is provided with a display unit that displays a predetermined screen for the user using the information processing terminal based on the information requested by the user using the information processing terminal received from the server device via the network.

[0006] [Patent Document 1] JP 2013-164681 A Summary of the Invention [Problem to be solved by the invention]

[0007] According to the information management system described in Patent Document 1, information about buildings can be appropriately managed, and users can easily obtain the information they need. In the design of the BIM design model for the above-mentioned system architecture, a BIM design model is created in which the plan and height dimensions of the building are set, multiple exterior materials of predetermined dimensions are arranged around the periphery of the building, and a folded-plate roof with a predetermined slope is arranged on the roof. This BIM design model makes it possible to directly imagine the exterior of the building.

[0008] After the architectural designer has created the BIM design model, the structural designer imports the BIM design model into, for example, high-performance integrated structural calculation software on a user terminal, creates a calculation model within the calculation software, enters specification information for the various components that make up the calculation model, and then performs structural calculations.

[0009] However, in reality, due to insufficient data compatibility between BIM software and high-performance integrated structural calculation software, when creating a structural calculation model, structural designers input plan and height dimensions based on the BIM design model and design drawings, etc., and then create the structural calculation model by registering components that are not registered in the high-performance integrated structural calculation software, or by selecting components of a similar weight from among the registered components.

[0010] Therefore, since creating a structural calculation model requires a great deal of time and effort, there is a demand for devices and programs that can quickly and automatically create (data convert) data for structural calculation models based on the BIM design model.

[0011] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a data conversion device and program for linking heterogeneous models that can quickly and automatically create data for a structural calculation model based on a BIM design model. [Means for solving the problem]

[0012] In order to achieve the above object, one aspect of the data conversion device for heterogeneous model integration according to the present invention comprises: A data conversion device for heterogeneous model linkage that converts first data related to a BIM design model of a building included in a system architecture into second data related to a structural calculation model, An acquisition unit that acquires the first data; A conversion unit that converts the first data into the second data; a storage unit that stores the created second data; The first data is characterized in that it includes provisional structural component data for each object constituting the BIM design model.

[0013] According to this aspect, the first data on the BIM design model is converted into the second data on the structural calculation model by the conversion unit, so that the second data can be automatically created based on the first data, and the input of data for creating the structural calculation model by the structural designer can be suppressed or prevented. In addition, the first data includes provisional structural member data on each object constituting the BIM design model, so that the quick data conversion to the second data is promoted, and the input work for the structural calculation software can be reduced.

[0014] Here, the term "provisional structural member", which can also be called "provisional member" or "temporary structural member", means a member that is provisionally set before structural calculations are performed, and the provisional structural member data is literally data related to provisional structural members. Even if it is a provisional structural member, for example, the specifications of each member such as the exterior columns, exterior beams, and center columns can be roughly set based on past performance from the scale of the building, and therefore the specifications do not deviate significantly from the members (called actual members) that are set when the structural designer creates the BIM structural model. Therefore, the basic information in the first data can be linked to the second data that can be read into high-performance integrated structural calculation software.

[0015] Furthermore, since the building to be designed is a building included in a system architecture, it tends to have longer spans than ordinary buildings, and because this increases the time required for data input, the effect of the data conversion device of this embodiment becomes even more pronounced in the creation of a structural calculation model of a building included in this system architecture.

[0016] In another aspect of the data conversion device for heterogeneous model linkage according to the present invention, The provisional structural component corresponding to the provisional structural component data is characterized in that it is a component that is set for each object to enable a rough estimate based on a BIM design model.

[0017] According to this aspect, the provisional structural member data corresponds to the provisional structural member data, and is set for each object to enable a rough estimate based on the BIM design model, so that the steel frame weight of the entire building can be calculated based on the provisional structural members that make up the BIM design model. Therefore, it is possible to calculate the steel frame weight with a much higher accuracy than, for example, a method of calculating the steel frame weight of the entire building from the steel frame weight per tsubo in past performance. In other words, by applying the provisional structural member data, it is possible to realize both a quick data conversion to a structural calculation model and a rough estimate with a high accuracy at the BIM design model creation stage.

[0018] In another aspect of the data conversion device for heterogeneous model linkage according to the present invention, The second data includes target building specific information data, including plan dimensions and height dimensions, specific to the building to be designed, as well as system building specific information data specific to the system building, and the system building specific information data is preset as a default value for the second data.

[0019] According to this embodiment, the second data includes system-architectural-specific information data specific to the system architecture, and the system-architectural-specific information data is pre-set as a default value for the second data, thereby making data conversion from the first data regarding the BIM design model of a building included in the system architecture to the second data regarding the structural calculation model even smoother, thereby reducing the input effort required for structural calculation software.

[0020] In another aspect of the data conversion device for heterogeneous model linkage according to the present invention, The second data includes: Periphery model data on a periphery model having plan dimensions and height dimensions of the building, exterior columns located on the periphery, and exterior beams connecting adjacent exterior columns; Center pillar data relating to a center pillar to be placed inside the perimeter model as necessary; Girder data relating to a girder connecting the exterior columns to each other or connecting the exterior columns to the center columns; Vertical brace data relating to a vertical brace to be incorporated into the perimeter model; column connection data relating to column connections that are incorporated into the perimeter model and connect adjacent exterior columns; Sub-beam data relating to a sub-beam perpendicular to the main beam; Rafter data relating to a rafter connecting the exterior column and the small beam; Horizontal brace data regarding horizontal braces; The data includes foundation data relating to a continuous footing under the outer columns and an independent footing under the center columns.

[0021] According to this aspect, the second data regarding the structural calculation model of the building included in the system building includes outer perimeter model data, center column data, main girder data, vertical brace data, column connection data, minor beam data, rafter data, horizontal brace data, and foundation data, making it possible to create a structural calculation model that enables structural calculations using high-performance integrated structural calculation software.

[0022] Moreover, one aspect of the program according to the present invention is A program for causing a computer to convert first data related to a BIM design model of a building included in a system building into second data related to a structural calculation model, the program comprising: acquiring the first data; converting the first data into the second data; and storing the created second data. The first data is characterized in that it includes provisional structural component data for each object constituting the BIM design model.

[0023] According to this aspect, a program installed or downloaded to a personal computer or the like acquires first data related to a BIM design model of a building included in a system building, converts the first data into second data related to a structural calculation model, and stores the second data, thereby enabling automatic creation of the second data based on the first data, and suppressing or eliminating the need for a structural designer to input data for creating a structural calculation model. In addition, since the first data includes provisional structural member data related to each object constituting the BIM design model, rapid data conversion to the second data is promoted, and the effort required for inputting data into the structural calculation software can be reduced.

[0024] In another aspect of the program according to the present invention, The second data includes target building specific information data, including plan dimensions and height dimensions, specific to the building to be designed, as well as system building specific information data specific to the system building, and the system building specific information data is preset as a default value for the second data.

[0025] According to this embodiment, the second data includes system-architectural-specific information data specific to the system architecture, and the system-architectural-specific information data is pre-set as a default value for the second data, thereby making data conversion from the first data regarding the BIM design model of a building included in the system architecture to the second data regarding the structural calculation model even smoother. Effect of the Invention

[0026] As can be understood from the above description, the data conversion device and program for linking different types of models according to the present invention make it possible to quickly and automatically create data for a structural calculation model based on a BIM design model.

[0028] Hereinafter, an example of a data conversion device for heterogeneous model linkage according to an embodiment will be described with reference to the accompanying drawings. In this specification and the drawings, substantially identical components may be denoted by the same reference numerals to avoid redundant description.

[0029] [Data conversion device for heterogeneous model integration according to the embodiment] An example of a data conversion device for heterogeneous model linkage according to an embodiment will be described with reference to Fig. 1 to Fig. 7. Here, Fig. 1 is a diagram showing an example of a hardware configuration of a data conversion device for heterogeneous model linkage according to an embodiment, and Fig. 2 is a diagram showing an example of a functional configuration of a data conversion device for heterogeneous model linkage. Also, Figs. 3 to 7 are diagrams showing display examples on a display screen of the data conversion device for heterogeneous model linkage.

[0030] The data conversion device 10 for heterogeneous model linkage (hereinafter, data conversion device) is a data conversion device that is applied when, for example, a structural design engineer converts first data related to a BIM design model into second data related to a structural calculation model.

[0031] Although not shown in the figure, various user terminals such as design engineers and structural engineers, production engineers, cost estimation user terminals, construction plan user terminals, and actual construction user terminals (none of which are shown) are connected to the shared server via a network, and BIM models (BIM design model, BIM structural model, BIM production model, etc.) created by each design user terminal are transmitted to and stored in the shared server each time, and a design support system is constructed in which user terminals to which access rights have been granted can access the shared server. In this design support system, the data conversion device 10 for heterogeneous model linkage may be a device constituting the design user terminal of the structural engineer, or may be a device constituting the shared server. That is, the structural engineer may use his own data conversion device 10 to convert first data related to the BIM structural model into second data for the structural calculation model, or the structural engineer may use the data conversion device 10 in the shared server to convert the first data into the second data.

[0032] This design support system includes a closed network where information is shared only within a single house manufacturer or other company, as well as an open network that allows information to be shared with external organizations (such as material and equipment suppliers owned by material and equipment suppliers who work together at the stages of production design, facility design, construction planning, etc.) In addition, the shared server may be a cloud server that allows multiple users to share various types of application software in addition to storing data.

[0033] Before describing the data conversion device 10 for linking different types of models according to the embodiment, the creation of a BIM design model used when a structural designer creates a structural calculation model will be described.

[0034] The creation of a BIM design model by a design engineer using a design user terminal is carried out during the planning stage of a building included in a system architecture. Autodesk Revit (registered trademark) (manufactured by Autodesk) is installed or downloaded as BIM software onto the design engineer's user terminal, and is started up during design. During the planning stage, by looking at the image data (BIM design model) of a three-dimensionally modeled building, the designer can directly imagine the exterior and layout design of the building.

[0035] Here, buildings included in the system architecture include logistics warehouses, retail stores such as drug stores and convenience stores, etc.

[0036] The design engineer selects one of the product types set for each structure and purpose. Here, the product type includes, for example, the structure of the steel-framed structural frame, such as one-story or two-story, a structure using single beams, or a structure using truss beams. The purpose includes a logistics warehouse or a retail store. The "product" includes products developed and commercialized by Daiwa House Industry Co., Ltd., such as "Frest," "Comfort," "Lead," and "Lead Free."

[0037] The design engineer selects from among the products the product that is best suited to the structure and use of the system-built building to be designed, and then selects the exterior materials specific to the product (standard exterior material manufacturers, product numbers, etc.). In addition, the engineer selects whether or not to include a waist wall below the exterior material. After selecting the product, exterior material, and whether or not to include a waist wall, the engineer sets building information including the floor and height dimensions of the building, and a BIM design model (an example of a BIM design model) is created in the early stages of design for a retail store or similar.

[0038] FIG. 3 shows a BIM design model 40 in the initial stage of a building included in a system building, displayed on the display unit 24 (display screen) of the data conversion device 10.

[0039] The BIM design model 40 has an exterior wall 42 formed of multiple exterior materials 41 along the X and Y directions of a roughly rectangular shape when viewed from above, a waist wall 43 below the exterior material 41, a slab footing 47 supporting the waist wall 43, and a folded plate roof 45 with a predetermined water gradient.

[0040] Next, architects use this early-stage BIM design model to create a tentative structural component layout model (another example of a BIM design model) that will enable highly accurate rough estimates.

[0041] The BIM design model, which is a provisional structural member arrangement model for a system building, is, for example, a rectangle in plan view, and exterior columns are arranged at the grid points between multiple grid lines extending in the X and Y directions and the exterior walls, and center columns are arranged inside the exterior walls at one or multiple grid points formed by each grid line, as necessary. For example, the necessity of arranging center columns and their arrangement positions and number when they are arranged are set in accordance with the arrangement rules. The necessity of installing center columns is influenced by snow depth (snow load), which is one of the design conditions for a system building building, but an example of an arrangement rule is that center columns are not required when the column spacing in the direction parallel to the water gradient is, for example, 14 m or less, and the column spacing in the direction perpendicular to the water gradient is, for example, 6 m or less, with respect to the overall plan dimensions of the building, and center columns are arranged under other conditions.

[0042] By setting exterior beams (eaves beams and gable beams) that connect the exterior columns, a perimeter model is created from the exterior columns and exterior beams. In addition, a large beam is placed to connect the exterior columns and center columns, and a small beam that connects the large beam to the exterior columns, a rafter that connects the small beam to the exterior columns, a small beam to the rafter, an exterior beam, etc. are placed in the planar grid formed by the exterior beams.

[0043] For example, when setting the main beam, a provisional structural member with specifications according to its length and load width is set. When setting the minor beam, the pitch and length of the minor beam are set according to the specifications of the folded plate that constitutes the folded plate roof and the snow load, and a provisional structural member with a predetermined specification is set. When setting the vertical brace, the number and specifications of the vertical brace are set based on the larger horizontal force between the horizontal force during an earthquake calculated from the building weight and design seismic intensity according to the scale of the building, and the horizontal force during wind according to the standard wind speed. Since the multiple vertical braces with the number and specifications set need to be installed in a position that avoids entrance and exit openings, window openings, etc., the vertical brace is installed in a position that the designer considers to be suitable.

[0044] FIG. 4 shows a provisional structural member arrangement model 50 (BIM design model) capable of realizing a rough estimate, which is drawn by the drawing unit 23 of the data conversion device 10 and displayed on the display unit 24 (display screen).

[0045] The BIM design model 50 is a model in which provisional structural members are assigned to each object. The BIM design model 50, which is rectangular in plan view, has an outer perimeter model 65 formed by exterior columns 61 spaced apart along the X and Y directions and exterior beams 62 connecting adjacent exterior columns 61.

[0046] The outer perimeter model 65 is provided with a column joint 63 in the middle of the outer column 61, and cross-shaped vertical braces 64 above and below the column joint 63.

[0047] Inside the rectangular outer perimeter model 65 in a plan view, multiple center columns 66 (two in the illustrated example) are arranged, a main girder 67 is arranged connecting the outer columns 61 and the center columns 66, a minor beam 68 connecting the main girder 67 and the outer columns 61, a tie beam 69 connecting the minor beam 68 and the outer columns 61, a horizontal brace 70 arranged within a planar lattice formed by the minor beam 68 and the tie beam 69, the outer beam 62, etc.

[0048] A slab 47 is placed below each of the outer columns 61 that make up the perimeter model 65, and an independent footing (not shown) is placed below the center column 66. In the illustrated example, a eaves truss 71 is placed above a part of the perimeter model 65 (the front side in FIG. 4).

[0049] By setting provisional structural components for each object in the BIM design model 50, highly accurate rough estimates can be made at the design stage.

[0050] A structural design engineer applies first data related to a BIM design model 50 to the data conversion device 10 to automatically create second data for a structural calculation model (data conversion). Hereinafter, an example of a data conversion device according to an embodiment will be described with reference to Figs. 1 and 2 and Figs. 5 to 7.

[0051] As shown in FIG. 1, the data conversion device 10 is an information processing device such as a personal computer (PC), a workstation (WS), or a tablet, all of which are constituted by a computer.

[0052] The computer constituting the data conversion device 10 includes a CPU (Central Processing Unit) 11, a main memory device 12, an auxiliary memory device 13, a communication IF (interface) 14, and an input / output IF 15, which are interconnected by a connection bus 16. The main memory device 12 and the auxiliary memory device 13 are computer-readable recording media. Note that the above components may be provided separately, or some of the components may not be provided.

[0053] The CPU 11 is also called an MPU (Microprocessor) or a processor, and may be a single processor or a multiprocessor. The CPU 11 is a central processing unit that performs overall control of the data conversion device 10, which is a computer. The CPU 11, for example, develops a program stored in the auxiliary storage device 13 in an executable manner in the working area of ​​the main storage device 12, and controls peripheral devices through the execution of the program, thereby providing a function that meets a predetermined purpose.

[0054] The main storage device 12 stores computer programs executed by the CPU 11, data processed by the CPU 11, etc. The main storage device 12 includes, for example, a flash memory, a RAM (Random Access Memory), and a ROM (Read Only Memory). The auxiliary storage device 13 stores various programs and various data in a readable and writable recording medium, and is also called an external storage device. The auxiliary storage device 13 stores, for example, an OS (Operating System), various programs, various tables, etc. The OS includes, for example, a communication interface program that transfers data to and from an external device connected via the communication IF 14. The external device includes, for example, an information processing device such as a personal computer (PC), a workstation (WS), a server, or a mobile terminal connected to a network, and an external storage device.

[0055] The auxiliary storage device 13 is used, for example, as a storage area that assists the main storage device 12, and stores computer programs executed by the CPU 11, data processed by the CPU 11, etc. The auxiliary storage device 13 is a silicon disk including a non-volatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD: Hard Disk Drive) device, a solid state drive device, etc. Examples of the auxiliary storage device 13 include a drive device for a removable recording medium such as a CD drive device, a DVD drive device, and a BD drive device. Examples of the removable recording medium include a CD, a DVD, a BD, a USB (Universal Serial Bus) memory, and an SD (Secure Digital) memory card, etc.

[0056] The communication IF 14 is an interface with a network to which the data conversion device 10 and the like are connected. The communication IF 14 is connected to a shared server via the network, and downloads various application software used in creating a structural calculation model, and receives first data related to a BIM design model 50 shown in FIG. 4 that is created by a design engineer and stored in the shared server.

[0057] The input / output IF 15 is an interface for inputting and outputting data between devices connected to the data conversion device 10. For example, input devices such as a keyboard, a touch panel, a mouse, or the like, and a microphone are connected to the input / output IF 15. The data conversion device 10 receives, via the input / output IF 15, operation instructions from an operator who operates the input device.

[0058] In addition, for example, a display device such as a liquid crystal panel (LCD: Liquid Crystal Display) or an organic EL panel (EL: Electroluminescence) and an output device such as a printer and a speaker are connected to the input / output IF 15. The data conversion device 10 outputs data and information processed by the CPU 11 and data and information stored in the main storage device 12 and the auxiliary storage device 13 via the input / output IF 15.

[0059] 2, the data conversion device 10 provides various functions of at least an acquisition unit 21, a conversion unit 22, a drawing unit 23, a display unit 24, and a storage unit 25 by executing a program by a CPU 11. At least a part of the above processing functions may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), or the like, and similarly, at least a part of the above processing functions may be a dedicated LSI (large scale integration) such as an FPGA (Field-Programmable Gate Array), a numerical calculation processor, an image processing processor, or other digital circuits, or the like.

[0060] The acquisition unit 21 acquires first data related to a BIM design model stored by a structural designer in, for example, a shared server, and stores (stores) the data in the storage unit 25, while receiving application software stored in the shared server. The structural designer creates a structural calculation model 80 (see FIG. 7 ), executes structural calculations, and creates a BIM structural model (not shown) that satisfies structural safety. The created BIM structural model is transmitted to the shared server via the acquisition unit 21.

[0061] The first data acquired by the acquisition unit 21 includes span data and height data in the X and Y directions of the BIM design model 50, as well as provisional structural component data (the placement position of each component, the component length, etc.) regarding various provisional structural components shown in FIG.

[0062] More specifically, the first data includes the centerline, span, floor height, vertical movement of nodes, exterior columns and beams, various temporary structural components such as independent foundations and slab foundations, as well as roof loads and exterior wall loads.

[0063] The conversion unit 22 takes in the first data stored in the storage unit 25, and converts it into second data that can be taken in when creating a structural calculation model using highly functional integrated structural calculation software.

[0064] To explain an example of high-performance integrated structural calculation software, Super Build (registered trademark) / SS7 (manufactured by Union System Co., Ltd.) and BUS-6 (manufactured by Structural Systems Co., Ltd.), which are high-performance integrated structural calculation software for RC / SRC / S-construction buildings, are installed on the user terminal of the structural designer. Here, RC construction refers to reinforced concrete construction, SRC construction refers to steel-reinforced concrete construction, and S construction refers to steel-frame construction.

[0065] The second data automatically created by the data conversion device 10 is imported into the user terminal of the structural designer, a structural calculation model is created in the structural calculation software, and structural calculation is executed. ST-Bridge (manufactured by General Incorporated Association building SMART Japan), which is data linking software connecting the structural calculation software and the BIM software, is installed on the user terminal of the structural designer, and Autodesk Revit (registered trademark) (manufactured by Autodesk) is also installed as the BIM software. By starting these software, the structural calculation model (which is not a BIM model and is therefore a non-BIM calculation model) is converted into a BIM structural model.

[0066] To start the conversion unit 22, as shown in FIG. 5, with the BIM design model 50 displayed on the display screen of the display unit 24 (while the first data is being loaded), press "Revit to SS7 link tool" (add-in tool 30) from among the multiple add-in tools displayed on the display screen 24, and select "SS7 linked data output" (menu 32) from among the multiple selection menus.

[0067] By selecting this menu 32, the first data is converted into the second data by the conversion unit 22. Here, the second data is, for example, CSV data, an example of which is shown in FIG. 6. The second data includes target building specific information data including plan dimensions and height dimensions that are specific to the target building. Here, FIG. 6 is an example of output CSV data displayed in Excel, with three types of Excel data displayed overlapping each other. The automatically created second data is stored in the memory unit 25.

[0068] Here, the storage unit 25 includes system-architecture-specific information data that is specific to the system architecture, and the system-architecture-specific information data is preset and stored as a default value of the second data. For example, in the case of a system architecture, the foundation generally has a strip footing under the exterior columns and an independent footing under the center columns. This is because, for example, the exterior columns are arranged with a span of about 2 m, and therefore, from the standpoint of economy and workability, the foundations under the exterior columns corresponding to each exterior column are formed as a continuous strip footing rather than an independent footing. On the other hand, one or more center columns are independent, so an independent footing is applied.

[0069] In this way, the foundation type corresponding to each temporary structural member is preset as a default value. Furthermore, the rebar diameter (D10 for SD295A, D22 for SD345, etc.) applied to the reinforced concrete foundation is also preset as a default value.

[0070] As another example, when vertical braces are incorporated into the perimeter model, the default value is preset to two levels of vertical braces, with column ties being placed in the middle layer between them.

[0071] The second data, which is csv data, is data that can be read into, for example, Super Build / SS7, and by reading the second data into the structural calculation software, a structural calculation model 80 as shown in Figure 7 is created.

[0072] According to the data conversion device 10, the first data regarding the BIM design model is converted into the second data regarding the structural calculation model 80 by the conversion unit 22, thereby making it possible to automatically create the second data based on the first data, thereby reducing or preventing the structural design staff from inputting data for creating the structural calculation model.

[0073] Furthermore, since the first data includes provisional structural component data for each object that constitutes the BIM design model, rapid data conversion to the second data is facilitated.

[0074] In addition, the present invention is not limited to the configuration shown here, and may be implemented in other embodiments in which other components are combined with the configurations and the like of the above-mentioned embodiment.
