Description

Technical Field

[0001] The present invention relates to an information processing apparatus and a program.

Background Art

[0002] In recent years, in the fields of architecture and facilities, the use of BIM (Building Information Modeling) software has been progressing (for example, see Patent Document 1 below). BIM software is software for constructing a BIM model including a 3D model corresponding to a building and attribute information. A user can set and change parameters of the attribute information on the BIM software. Then, this setting and change are reflected in the 3D model.

[0003] Also, when designing a part of a building structure, for example, a system toilet, using BIM software, after loading attribute information related to the system toilet as a family into a project file used in the BIM software, the setting and change of the attribute information are performed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] As mentioned above, loading a system toilet family into a project file, for example, results in a large amount of data due to the variety of attribute information (complexity of choices). Furthermore, this system toilet is merely an example of a structural component of a building; actual buildings contain multiple structures, resulting in a very large amount of data for the entire BIM model corresponding to that building. This can impair the usability of the software, such as by worsening usability.

[0006] In view of the problems described above, the present invention aims to provide an information processing device and program that can reduce the amount of data used in BIM software. [Means for solving the problem]

Embodiments for Carrying Out the Invention

[0014] Hereinafter, a plurality of embodiments of the present invention will be described with reference to the accompanying drawings. For ease of understanding of the description, the same reference numerals are given to the same components and steps in each drawing as much as possible, and duplicate descriptions are omitted.

[0015] ===First Embodiment=== First, a first embodiment of the present invention will be described.

[0016] ≪Hardware Configuration≫ FIG. 1 is a diagram schematically showing an example of the hardware configuration of an information processing apparatus 1. The information processing apparatus 1 generates a BIM model corresponding to a building by incorporating BIM parts corresponding to a structure as a part of the building. Note that the building may be, for example, a building or a commercial facility, and the structure may be, for example, a device such as a system toilet, a wall, a pillar, or the like.

[0017] Although not shown, the information processing apparatus 1 can transmit and receive data to and from an external device (server device or terminal device) via a communication network such as the Internet, a telephone line, or an intranet, and is, for example, a computer such as a PC or a tablet.

[0018] As shown in FIG. 1, the information processing apparatus 1 includes a control device 2, a communication device 5, a storage device 6, a display device 7, and an input device 8 as main parts of the hardware configuration. The control device 2 is mainly configured to include a CPU (Central Processing Unit) 3 and a memory 4.

[0019] In the control device 2, the CPU 3 executes a predetermined program stored in the memory 4 or storage device 6, etc., thereby functioning as various functional means. Details of these functional means will be described later.

[0020] The communication device 5 consists of a communication interface and the like for communicating with external devices. The communication device 5 transmits and receives various types of information, for example, with other information processing devices (not shown) or with communication terminal devices such as mobile phones and smartphones.

[0021] The storage device 6 is composed of a hard disk or the like. This storage device 6 stores various programs, various information, and processing result information necessary for executing processing in the control device 2.

[0022] The display device 7 is a display responsible for display functions and is capable of displaying various images and videos. The input device 8 is a keyboard or the like, responsible for input functions and is capable of detecting the user's input position for various images. However, the display device 7 and the input device 8 may be a single unit (such as a touch panel).

[0023] Furthermore, the information processing device 1 can be implemented using a dedicated or general-purpose PC, tablet, or other information processing device. The information processing device 1 may consist of a single information processing device or multiple information processing devices distributed across a communication network. Also, Figure 1 only shows a portion of the main hardware configuration of the information processing device 1; the information processing device 1 may have other configurations commonly found in information processing devices such as PCs and tablets.

[0024] ≪Functional means≫ Figure 2 is a schematic block diagram showing an example of the functional means of the information processing device 1 shown in Figure 1. As shown in Figure 2, the information processing device 1 first includes a storage means 10 as the main functional component.

[0025] The storage means 10 is implemented by one or more storage devices 6. Other functional means, described later, are implemented by the control device 2 executing various programs stored in the storage devices 6, etc.

[0026] The storage means 10 has the function of storing part information 10A, BIM parts 10B, overall attribute information group 10C, partial attribute information group 10D, and BIM model 10E.

[0027] Part information 10A is data for generating BIM part 10B. Part information 10A may be, for example, data corresponding to the members that make up the structure described later (3D data of the member, and member ID, etc.).

[0028] BIM part 10B is data corresponding to a structure as part of a specific building. Specifically, it consists of 3D data of the structure and a BIM part ID. BIM part 10B is used to generate BIM model 10E.

[0029] The overall attribute information group 10C consists of multiple types of attribute information and an overall attribute ID. The overall attribute information group 10C is linked to each BIM part 10B. The parameters of each of these attribute information items can be changed by the user. Here, "linking" may also refer to linking the IDs of each other (the same applies to various types of linking below). Specific examples of attribute information will be described later.

[0030] The partial attribute information group 10D consists of some of the attribute information and partial attribute IDs from the overall attribute information group 10C. The partial attribute information group 10D is also linked to each BIM part 10B. Here, "some" refers to one or more types of attributes.

[0031] BIM Model 10E is data corresponding to a specific building. Specifically, it consists of the building's 3D data and its BIM Model ID.

[0032] Furthermore, as shown in Figure 2, external application software 11 (first software) and BIM software 16 (second software) are downloaded and installed on the information processing device 1. The external application software 11 and BIM software 16 are each launched individually in response to user operations to realize their respective functions.

[0033] The information processing device 1 comprises, as the main functional components realized by the external application software 11, a receiving means 12, a first modeling means 13, an extraction means 14, and an output means 15. Furthermore, the information processing device 1 comprises, as the main functional components realized by the BIM software 16, a receiving means 17 and a second modeling means 18.

[0034] Reception means 12 and reception means 17 are functional means that receive various operation instructions from the user, as will be described later. Reception means 12 also receives setting inputs such as parameters of the overall attribute information group 10C from the user.

[0035] The first modeling means 13 is a functional means that generates a BIM part 10B based on the overall attribute information group 10C (parameters of each attribute information set by the user) when the receiving means 12 receives user operation instructions. The first modeling means 13 may also generate the BIM part 10B by combining part information 10A stored in the storage means 10.

[0036] Furthermore, the first modeling means 13 can change the range of the BIM part 10B. This "range" may be, for example, a single device (structure), multiple adjacent devices (structures), multiple devices connected by a flow path, or multiple devices (structures) within a predetermined spatial range. Here, "device" refers to, for example, a system toilet. This point will be discussed later.

[0037] The BIM part 10B generated by the first modeling means 13 is stored in the storage means 10.

[0038] The extraction means 14 is a functional means that, upon receiving user operation instructions from the reception means 12, extracts a partial attribute information group 10D (a portion of the attribute information from the multiple types of attribute information included in the overall attribute information group 10C) from the overall attribute information group 10C (a portion of the attribute information included in the multiple types of attribute information included in the overall attribute information group 10C) associated with the BIM part 10B. The extraction means 14 also associates the extracted partial attribute information group 10D with the BIM part 10B.

[0039] Here, Figure 3 is a table illustrating an example of attribute information as a partial attribute information group 10D extracted from the overall attribute information group 10C, which includes multiple types of attribute information.

[0040] As shown in Figure 3, the attribute information included in the overall attribute information group 10C includes, for example, the number of units, fixture pitch, fixture end dimensions, color, part number, release date, and service life. Of these, attribute information such as the number of units, fixture pitch, fixture end dimensions, and color is necessary for manufacturing (estimation or production). In addition, attribute information such as part number, release date, and service life corresponds to the structure that BIM part 10B is related to. This is basic information (however, the part number may be treated as information necessary for manufacturing). Note that "device" here may also refer to the components that make up a device. For example, if the device is a system toilet, the device may be a single toilet bowl (urinal or toilet bowl).

[0041] The attribute information included in the partial attribute information group 10D includes, for example, the number of units, the equipment pitch, the equipment end dimensions, and the color. As shown in Figure 3, it is preferable that the partial attribute information group 10D includes at least all of the attribute information related to estimation or production from the overall attribute information group 10C.

[0042] The output means 15 is a functional means that outputs a partial attribute information group 10D to the storage means 10 when the receiving means 12 receives an operation instruction from the user. The storage means 10 stores this partial attribute information group 10D. Alternatively, the BIM part 10B generated by the first modeling means 13 and the partial attribute information group 10D associated with the BIM part 10B may be output to the receiving means 17 of the BIM software 16. In the latter case, the receiving means 17 receives the user instruction information and also receives the BIM part 10B and partial attribute information group 10D output from the output means 15.

[0043] The second modeling means 18 is a functional means that generates a BIM model 10E by incorporating multiple BIM parts 10B, each associated with a partial attribute information group 10D, when the receiving means 17 receives user operation instructions.

[0044] Furthermore, the information processing device 1 is equipped with a display means 19 as a functional means. The display means 19 is a functional means for displaying various screens. These various screens include, for example, an operation screen for the user to perform various operations, a display screen for displaying part information 10A, BIM parts 10B, a group of partial attribute information 10D, and a BIM model 10E, etc.

[0045] Although the partial attribute information group 10D was described as being part of the overall attribute information group 10C, this "part" may be modified as appropriate by user instructions (the reception means 12 will receive these instructions). In other words, the amount of information (granularity of attributes) that should be linked to the BIM model 10E changes as the phases related to construction progress, such as planning, design (basic design, detailed design), construction, completion, and maintenance of the building. Therefore, it may be possible to change the "part" according to the content of the phase.

[0046] For example, in the planning phase, the only equipment specification required as the partial attribute information group 10D is A-1 in Figure 3. Furthermore, in the basic design phase, attribute information regarding the fitting of BIM part 10B to the building is required. Therefore, the partial attribute information group 10D for BIM part 10B consists of the fixture specifications (A-1), the number of units (A-2), the fixture pitch (A-3), and the fixture end dimensions (A-4) as shown in Figure 3. Furthermore, in the detailed design phase, more detailed attribute information will be required. Therefore, the partial attribute information group 10D will consist of the following: A-1 fixture specifications, A-2 number of units, A-3 fixture pitch, A-4 fixture end dimensions, A-5 piping type, A-6 piping exit direction, A-7 color, B-4 part number, B-5 ​​product name, B-7 material, B-9 flushing water volume, B-10 water supply load unit, B-11 power consumption, and B-12 power consumption.

[0047] Alternatively, from another perspective, the above "parts" may be modified depending on the user's attributes. Here, user attributes may refer to occupations such as architectural designers, construction engineers, clients, contractors, and maintenance workers.

[0048] <<Processing Flow>> The following describes an example of the process by which the information processing device 1 generates the BIM model 10E, using the flowchart in Figure 4. Note that the order and content of the following steps can be changed as appropriate.

[0049] (Step SP1) The user inputs the overall attribute information group 10C (parameters for each attribute information, etc.) on an operation screen not shown in the diagram. The input overall attribute information group 10C is received by the reception means 12. The overall attribute information group 10C is linked to the BIM part 10B. After step SP1 is completed, the process moves on to step SP2.

[0050] (Step SP2) The first modeling means 13 generates a BIM part 10B based on the overall attribute information group 10C received by the receiving means 12 in step SP1. For example, if BIM part 10B is a system toilet and the attribute information included in the overall attribute information group 10C indicates a number of units, the first modeling means 13 generates a BIM part 10B with three toilets (urinals) lined up. The BIM part 10B generated by the first modeling means 13 is output by the output means 15 to the storage means 10, and is stored in the storage means 10 with the overall attribute information group 10C linked to it. After step SP2 is completed, the process moves on to step SP3.

[0051] (Step SP3) The extraction means 14 extracts a partial attribute information group 10D from the overall attribute information group 10C associated with the BIM part 10B generated by the first modeling means 13 in step SP2. Furthermore, the extraction means 14 associates the extracted partial attribute information group 10D with the BIM part 10B. This partial attribute information group 10D is then output by the output means 15 to the storage means 10, whereupon it is associated with the BIM part 10B and stored in the storage means 10. After step SP3 is completed, the process moves on to step SP4.

[0052] (Step SP4) The user inputs a generation instruction for the BIM model 10E on an operation screen (not shown). The input generation instruction is received by the receiving means 17. After step SP4 is completed, the process moves on to step SP5.

[0053] (Step SP5) The second modeling means 18 generates a BIM model 10E using the BIM parts 10B and partial attribute information group 10D stored in the storage means 10. As a specific example, the BIM parts 10B and partial attribute information group 10D stored in the storage means 10 may be loaded into a project file usable in the BIM software 16, and the second modeling means 18 may generate the BIM model 10E using this project file.

[0054] Figure 5 is a schematic diagram showing an example of a display screen 21 that displays the BIM model 10E generated by the second modeling means 18. As shown in Figure 5, the display screen 21 is a screen that includes a first display area 22 and a second display area 23.

[0055] The first display area 22 displays the partial attribute information group 10D. For example, if the structure is a urinal unit, setting the number of units to 3 means that the structure is a urinal unit with three urinal bodies lined up.

[0056] Furthermore, each attribute information and each parameter of the partial attribute information group 10D are extracted by the extraction means 14 of the external application software 11. However, these parameters may be modified by the user in the first display area 22 (before or after the BIM model 10E is generated). This is processed by the second modeling means 18. For example, attribute information with a "▼" in the first display area 22 can have its numerical value changed using a pull-down menu (for example, changing the number of units from 3 to 2). In addition, the fixture end dimensions in the first display area 22 can be changed by the user by entering numerical values.

[0057] The second display area 23 is an area that displays part or all of the BIM model 10E into which the BIM part 10B is incorporated. Based on the partial attribute information group 10D displayed in the first display area 22, the shape of the BIM part 10B displayed in the second display area 23 changes. This is performed by the second modeling means 18. For example, if the number of urinals in the first display area 22 is changed from 3 to 2, the number of urinals in the BIM part 10B corresponding to the urinal unit, which is the fixture displayed in the second display area 23, will change from 3 to 2.

[0058] Figure 6 is a schematic diagram showing the state in which the display range of the BIM model 10E is expanded by reducing the size of the BIM model 10E displayed in the second display area 23 shown in Figure 5. As shown in Figure 6, the second display area 23A, which expands the display range of the BIM model 10E, displays not only the urinal unit but also other items such as multiple toilets. In this way, it is possible to expand or narrow the display range of the BIM model 10E. This allows for detailed viewing or viewing the overall structure, improving usability.

[0059] Here, Figure 7 is a schematic diagram illustrating the setting and modification of the scope to which BIM part 10B corresponds. Note that Figure 7 corresponds to a design drawing showing one floor of a building. For example, in Figure 7, area A1 refers to the case where the area corresponding to BIM part 10B is a urinal unit, i.e., a fixture. Furthermore, in Figure 7, area A2 refers to the case where the area corresponding to BIM part 10B is a urinal unit, i.e., a piece of equipment. Furthermore, in Figure 7, area A3 refers to the case where the area to which BIM part 10B corresponds is a toilet room, i.e., a predetermined space. Thus, it is preferable that the range to which BIM part 10B corresponds can be changed in various ways.

[0060] Furthermore, the BIM model 10E generated by the second modeling means 18 in step SP5 is stored in the storage means 10. Returning to Figure 4, the process ends after step SP5 is completed.

[0061] <Effects> An information processing device 1 according to the first embodiment of the present invention is an information processing device 1 that generates a BIM model 10E corresponding to a building by incorporating BIM parts 10B corresponding to structures as part of the building, and comprises: a first modeling means 13 realized by first software (external application software 11) that generates BIM parts 10B based on a total attribute information group 10C which is a plurality of types of attribute information; an extraction means 14 realized by first software (external application software 11) that extracts a partial attribute information group 10D which is a subset of attribute information from the total attribute information group 10C and links the partial attribute information group 10D to the BIM parts 10B; and a second modeling means 18 realized by second software (BIM software 16) different from the first software (external application software 11) that generates a BIM model 10E by incorporating a plurality of BIM parts 10B to which each partial attribute information group 10D is linked. With this configuration, the external application software 11 generates the BIM part 10B, and the BIM software 16 generates the BIM model 10E using some attribute information (as project data), thus reducing the amount of data used by the BIM software 16. Furthermore, since the command operations for generating the BIM part 10B are performed by external application software 11, the operations in the BIM software 16 can be simplified.

[0062] Furthermore, in the information processing apparatus 1 according to the first embodiment of the present invention, the first modeling means 13 can change the range to which the BIM part 10B corresponds. This configuration makes it easier for the second modeling means 18 to generate the BIM model 10E. For example, by expanding the range of BIM parts 10B generated by the first modeling means 13, the work of combining multiple BIM parts 10B when the second modeling means 18 generates the BIM model 10E can be reduced, thus making it easier to operate in the BIM software 16.

[0063] Furthermore, the program according to the first embodiment of the present invention is a program that generates a BIM model 10E corresponding to a building by incorporating BIM parts 10B corresponding to structures as part of the building, and the computer functions as: a first modeling means 13 realized by first software (external application software 11) that generates BIM parts 10B based on a total attribute information group 10C which is a plurality of types of attribute information; an extraction means 14 realized by first software (external application software 11) that extracts a partial attribute information group 10D which is a subset of attribute information from the total attribute information group 10C and links the partial attribute information group 10D to the BIM parts 10B; and a second modeling means 18 realized by second software (BIM software 16) different from the first software (external application software 11) that generates a BIM model 10E by incorporating a plurality of BIM parts 10B to which each partial attribute information group 10D is linked. With this configuration, the external application software 11 generates the BIM part 10B, and the BIM software 16 generates the BIM model 10E using some attribute information (as project data), thus reducing the amount of data used by the BIM software 16. Furthermore, since the command operations for generating the BIM part 10B are performed by external application software 11, the operations in the BIM software 16 can be simplified.

[0064] ===Second Embodiment=== Next, a second embodiment of the present invention will be described. In the following description, points that overlap with the configuration and functions of the information processing device 1 according to the first embodiment will be omitted as appropriate.

[0065] ≪Functional means≫ Figure 8 is a schematic block diagram showing an example of the functional means of the information processing apparatus 1A according to the second embodiment of the present invention. As shown in Figure 8, the information processing device 1A comprises a storage means 30 and a display means 19 as the main functional components. The information processing device 1A also comprises a receiving means 12, a first modeling means 33, and an output means 15 as the main functional components realized by the external application software 11. Furthermore, the information processing device 1A comprises a receiving means 17, a second modeling means 38, and a linking means 31 as the main functional components realized by the BIM software 16. Note that the display means 19, reception means 12, output means 15, and reception means 17 are the same as in the first embodiment, so their explanation will be omitted.

[0066] The storage means 30 stores part information 10A, BIM part 10B, overall attribute information group 30C, and partial attribute information group 30D. Of these, part information 10A and BIM part 10B are the same as in the first embodiment, so their description is omitted.

[0067] The partial attribute information group 30D consists of one or more types of attribute information and partial attribute IDs that are set and modified by the user. The specific examples of attribute information included in the partial attribute information group 30D are preferably the same as those in the partial attribute information group 10D in the first embodiment.

[0068] The overall attribute information group 30C is formed by adding one or more types of attribute information related to the building, and an additional attribute ID which is the ID of said attribute information, to the partial attribute information group 30D linked to each BIM part 10B (an overall attribute ID may also be set for the overall attribute information group 30C). "One or more types of attribute information related to the building" may be, for example, the name of the building, the floor to which the structure corresponding to each BIM part 10B is installed, the area used by people who live or work in the building (such as distinction between men and women for toilets), and notes specific to each building. The content and parameters of each of these attribute information items can be pre-set or changed during the process through user interaction.

[0069] The first modeling means 33 is a functional means that generates a BIM part 10B based on a set of partial attribute information 10D set by the user, upon receiving user operation instructions from the receiving means 12. The set of partial attribute information 10D is associated with the BIM part 10B.

[0070] The second modeling means 38 is a functional means that generates a BIM model 10E by incorporating multiple BIM parts 10B, each of which is associated with a partial attribute information group 30D.

[0071] The linking means 31 links attribute information related to the building to the BIM model 10E generated by the second modeling means 38. As a result, the entire attribute information group 30C is linked to the BIM model 10E.

[0072] <<Processing Flow>> An example of the processing of the information processing device 1A according to the second embodiment of the present invention will be explained using the flowchart in Figure 9. Note that the order and content of the following steps can be changed as appropriate.

[0073] (Step SP11) The user inputs a group of partial attribute information 30D (parameters for each attribute information, etc.) on an operation screen not shown in the diagram. The input group of partial attribute information 30D is received by the receiving means 12. After step SP11 is completed, the process moves on to step SP12.

[0074] (Step SP12) The first modeling means 33 generates a BIM part 10B based on the partial attribute information group 30D received by the receiving means 12 in step SP11. The partial attribute information group 30D is associated with the BIM part 10B. The BIM part 10B generated by the first modeling means 13 is output to the storage means 10 by the output means 15, and is stored in the storage means 30 with the partial attribute information group 10D linked to it. After step SP12 is completed, the process moves on to step SP13.

[0075] (Step SP13) The user inputs a generation instruction for the BIM model 10E on an operation screen (not shown). The input generation instruction is received by the receiving means 17. After step SP13 is completed, the process moves on to step SP14.

[0076] (Step SP14) The second modeling means 38 generates a BIM model 10E by incorporating the BIM parts 10B stored in the storage means 10. After step SP14 is completed, the process moves on to step SP15.

[0077] (Step SP15) The linking means 31 links attribute information about the building, which has been pre-set and entered by the user, to the BIM model 10E.

[0078] Furthermore, each attribute and parameter of the partial attribute information group 30D may be modified by the user before or after the BIM model 10E is generated. This modification is then processed by the second modeling means 18.

[0079] Furthermore, the BIM model 10E generated by the second modeling means 38 in step SP15, and the overall attribute information group 40E, which combines the partial attribute information group 30D and the attribute information related to the building, are stored in the storage means 10. After step SP15 is completed, the process will end.

[0080] <Effects> An information processing device 1A according to a second embodiment of the present invention is an information processing device 1A that generates a BIM model 10E corresponding to a building by incorporating BIM parts 10B corresponding to structures as part of a building, and comprises: a first modeling means 33 realized by first software (external application software 11) that generates BIM parts 10B to which attribute information groups (partial attribute information groups 30D) are linked based on attribute information groups (partial attribute information groups 30D) which are one or more types of attribute information; a second modeling means 38 realized by second software (BIM software 16) different from the first software (external application software 11) that generates a BIM model 10E by incorporating a plurality of BIM parts 10B to which attribute information groups (partial attribute information groups 30D) are linked; and a linking means 31 realized by the second software (BIM software 16) that links attribute information related to the building to the BIM model 10E. This configuration allows for the use of attribute information related to the building (for example, the building's property name, the floor to which each BIM part 10B corresponds to the structure, and the usage area for people who live or work within the building (such as gender distinctions for toilets)) in the BIM model 10E, making it easier to order, produce, and ship structures (such as system toilets). Furthermore, this configuration allows for the selection of specific units, making it easier to order, produce, and ship them.

[0081] Furthermore, the program according to the second embodiment of the present invention is a program that generates a BIM model 10E corresponding to a building by incorporating BIM parts 10B corresponding to structures as part of the building, and the computer functions as a first modeling means 33 realized by first software (external application software 11) that generates BIM parts 10B to which attribute information groups (partial attribute information groups 30D) are linked based on one or more types of attribute information; a second modeling means 38 realized by second software (BIM software 16) different from the first software (external application software 11) that generates a BIM model 10E by incorporating multiple BIM parts 10B to which attribute information groups (partial attribute information groups 30D) are linked; and a linking means 31 realized by the second software (BIM software 16) that links attribute information related to the building to the BIM model 10E. This configuration allows for the easy ordering, production, and shipment of structures (such as toilets) by using attribute information about the building in the BIM model 10E (for example, the building's property name, the floor to which each BIM part 10B corresponds to the structure, and the areas used by people who live or work within the building (such as gender distinctions for toilets)). Furthermore, this configuration allows for the easy ordering, production, and shipment of only specific units.

[0082] ===Literal translation=== It should be noted that the present invention is not limited to the above-described examples. That is, designs modified by those skilled in the art to the above-described examples are also included within the scope of the present invention, as long as they retain the features of the present invention. Furthermore, the elements of the embodiments described above and the modifications described later can be combined to the extent that it is technically possible, and combinations thereof are also included within the scope of the present invention, as long as they retain the features of the present invention.

[0083] For example, in the first embodiment of the present invention, the first modeling means 13 is described as generating a BIM part 10B based on the overall attribute information group 10C. However, if the first modeling means 13 receives a change in the parameters of the attribute information included in the partial attribute information group 10D after the extraction means 14 has extracted the partial attribute information group 10D, the receiving means 12 may regenerate (modify) the BIM part 10B accordingly. In that case, the generated (modified) BIM part 10B may be stored in the storage means 10 separately from the BIM part 10B linked to the overall attribute information group 10C.

[0084] Furthermore, in the second embodiment of the present invention, the second modeling means 38 generates a BIM model 10E by incorporating a plurality of BIM parts 10B, each of which is associated with a partial attribute information group 30D, and the linking means 31 links attribute information related to the building to the BIM model 10E generated by the second modeling means 38. However, the second modeling means 38, the linking means 31, and the overall attribute information group 40D may be modified as follows. The overall attribute information group 30C is the partial attribute information group 30D plus attribute information other than that in the partial attribute information group 30D (attribute information related to BIM part 10B, just like in the partial attribute information group 30D). The linking means 31 then links the overall attribute information group 30C to the BIM part 10B. Furthermore, the second modeling means 38 generates a BIM model 10E by incorporating multiple BIM parts 10B, each of which is associated with a set of overall attribute information 30C. This eliminates the need to generate BIM parts 10B in the BIM software 16, and furthermore, the external application software 11 handles only some of the attribute information used by the BIM software 16, thus reducing the amount of data used.

[0085] Furthermore, in the first embodiment of the present invention, each attribute information of the overall attribute information group 10C is linked to the BIM part 10B. However, if the part information 10A includes 3D data, the overall attribute information group 10C may also include attribute information linked to the part information 10A. Similarly, in the second embodiment of the present invention, each attribute information of the partial attribute information group 30D is linked to the BIM part 10B. However, the partial attribute information group 30D may also be linked to the part information 10A.

[0086] Furthermore, as shown in Figure 10, the first information processing device 1B on which the external application software 11 is installed and downloaded, and the second information processing device 1C on which the BIM software 16 is installed and downloaded, may be separate entities. This approach reduces the processing load on each information processing device and improves security by allowing each person in charge (the person who owns each information processing device) to access different data.

[0087] To elaborate on Figure 10, the first information processing device 1B is equipped with a reception means 12, a first modeling means 13, an extraction means 14, an output means 54, a display means 19, and a storage means 40 as the main functional components. Of these, the reception means 12, the first modeling means 13, the extraction means 14, and the output means 54 are implemented by external application software 11. The memory means 40 stores part information 10A, BIM part 10B, overall attribute information group 10C, and partial attribute information group 10D. Furthermore, the output means 54 transmits the BIM parts 10B and the partial attribute information group 10D stored in the storage means 40 to the second information processing device 1C via a communication network (not shown). The other functional configurations of the first information processing device 1B will not be explained.

[0088] Furthermore, as shown in Figure 10, the second information processing device 1C is equipped with a reception means 17, a second modeling means 18, a display means 19, and a storage means 41 as the main functional components. Of these, the reception means 50 and the second modeling means 18 are implemented by BIM software 16. The memory means 41 stores the BIM part 10B, the partial attribute information group 10D, and the BIM model 10E. Furthermore, the receiving means 50 receives the BIM part 10B and the partial attribute information group 10D transmitted by the output means 54. The BIM part 10B and the partial attribute information group 10D received by the receiving means 50 are stored in the storage means 41. The other functional configurations of the second information processing unit 1C will not be explained.

[0089] Although Figure 10 illustrates that there may be multiple information processing devices when each functional configuration is the same as in the first embodiment of the present invention, it goes without saying that there may also be multiple information processing devices when each functional configuration is the same as in the second embodiment of the present invention.
