  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<Configuration of Design Support Apparatus According to First Embodiment>

  FIG. 1 shows an example of a configuration of a design support apparatus 100 according to an embodiment of the present invention. The design support apparatus 100 of the present embodiment can be functionally represented by a configuration including a receiving unit 10, a computer 20, and a display unit 30, as shown in FIG. The design support apparatus 100 of the present embodiment supports wall design performed by a building designer.

  When designing a wall inside a building, it is necessary to design a wall that satisfies predetermined conditions. However, the number of conditions to consider when designing a wall is enormous.

  For example, a wall (hereinafter, simply referred to as “LGS wall”) constituted by LGS (Light Gauge Steel) will be described as an example. The specification regarding the size of the skeleton of the wall base of the LGS wall is determined by the height of the LGS wall. In addition, in order to determine the height of the LGS wall, it is necessary to consider the sound insulation performance between the fire prevention compartment and the room. In addition, in a portion in contact with the underground outer wall, it is necessary to consider that the frame material of the LGS wall is made of stainless steel (SUS) instead of steel.

  As described above, the conditions to be considered when designing a wall are complicated and enormous, but in the past, architects have determined the specifications of each wall.

  On the other hand, in the field of architectural design, BIM (Building Information Modeling) is being utilized. When using BIM, a building designer creates a BIM model representing a three-dimensional model of a building to be designed and performs architectural design.

  When utilizing the BIM, the architect assigns attribute information indicating the specification of each object to each object in the BIM model representing the building to be designed. Thereby, for example, the specification of the wall object is determined. However, this method is not different from the conventional method because the specification of the wall is determined by the architect.

  Therefore, the design support apparatus 100 of the present embodiment automatically generates a wall in a building by using a room requirement table indicating required performance of each room in the building.

  In the present embodiment, information relating to the required performance of each room is extracted as a room requirement table from the BIM model represented by the object representing the shape of the building and the attribute information representing its specifications, and this room requirement table is used. Generate walls automatically. The room requirement table according to the present embodiment is an example of basic requirement information indicating the requirements of the room of the building to be designed.

  In the present embodiment, as shown in FIG. 2, a room requirement table RC including information on room requirements of a design target building and a basic object PM which is an object representing the shape of the design target building are managed separately. . Each piece of information in the room requirement table RC is information indicating required performance of each room in the building to be designed. By separately managing the room requirement table RC and the basic object PM, it is possible to appropriately and automatically generate a wall according to the required performance of each room of the building to be designed.

  Note that each piece of information in the room requirement table RC also includes information that is determined according to a request from the builder. Therefore, when each piece of information in the room requirement table RC is reflected on the basic object PM, the BIM model M to be designed is in a state in which the request of the builder is reflected.

  Hereinafter, the present embodiment will be specifically described.

  The receiving unit 10 receives information input by a user. The receiving unit 10 is realized by, for example, a keyboard, a mouse, or an input / output device that receives an input from an external device. In the present embodiment, the user inputs a design support instruction signal to the computer 20 via the receiving unit 10.

  The computer 20 includes a CPU (Central Processing Unit), a ROM (Read Only Memory) storing a program for realizing each processing routine, a RAM (Random Access Memory) for temporarily storing data, and a memory as storage means. , A network interface and the like. As shown in FIG. 1, the computer 20 functionally includes a basic requirement information storage unit 22, an object storage unit 24, a BIM model storage unit 25, an information acquisition unit 26, and a wall generation unit 28. Have.

  The basic requirement information storage unit 22 stores a room requirement table RC as basic requirement information representing the requirements of the room of the building to be designed. The room requirement table RC stores information on the required performance of each room.

  For example, the room requirement table RC includes information on sound insulation in each room, information on water use in each room, information on movable partitions in each room, information on radiation shielding in each room, information on electromagnetic shielding in each room, and the like. include. Further, the room requirement table RC may include information on a fire prevention section, information on the type of an outer wall, information on a room facing a blow-off, information on a partition wall in a toilet, and the like.

  FIG. 3 shows an example of the room requirement table RC. The room requirement table RC shown in FIG. 3 includes information “sound insulation setting” about sound insulation of each room, information “water use room” about water use of each room, and information “movable partition” about movable partition of each room. In addition, information “radiation shielding” regarding radiation shielding in each room and information “electromagnetic shielding” regarding electromagnetic shielding in each room are included. The wall of each room is generated using these pieces of information.

  The object storage unit 24 stores a basic object PM which is an object representing the shape of a building to be designed.

  The BIM model storage unit 25 stores a plurality of different BIM models representing a building to be designed.

  Building design work is often performed using multiple BIM models. As the plurality of BIM models, for example, a design model in which information on a design of a building is stored, a facility model in which information on equipment of a building is stored, a structural model in which information on a structure of a building is stored, and a fire section of the building For example, a zone model in which information relating to the information is stored.

  For example, a structural designer creates a structural model in consideration of the structure of a building to be designed. The structure model is configured to include an object representing the shape of the building related to the structure and attribute information given to the object.

  When the design work is performed by a plurality of BIM models, information necessary for generating a wall is distributed and stored in each BIM model. Therefore, in the present embodiment, based on the room requirement table RC representing the requirements of the room of the building, the basic object PM representing the shape of the building, and the information stored in the plurality of BIM models, the building requirement of the building to be designed is determined. Automatically generate each of the walls.

  The information acquisition unit 26 acquires the room requirement table RC stored in the basic requirement information storage unit 22. Further, the information acquisition unit 26 acquires the basic object PM stored in the object storage unit 24. Further, the information acquisition unit 26 acquires each piece of information stored in a plurality of different BIM models.

  The wall generation unit 28 generates each of the walls in the building to be designed based on the information acquired from the room requirement table RC, the basic object PM, and the plurality of BIM models acquired by the information acquisition unit 26. .

  FIG. 4 is an explanatory diagram for explaining generation of a wall. FIG. 4 shows a method for generating a wall composed of LGS members.

[Generation of wall according to exterior wall type]

  First, the generation of a wall according to the type of outer wall will be described.

  When generating a wall, if the generation target wall is a wall located on the back side of the outer wall, the wall generator 28 generates the wall according to the type of the outer wall. In steps A1 to A7 of FIG. 4, a specific method of generating a wall located on the back side of the outer wall is shown.

  Specifically, first, in step A1 shown in FIG. 4, the wall generation unit 28 sets a necessary range of the wall base. For example, the wall generation unit 28 sets the wall on the back side of the wall facing the outside as a range where the wall base is necessary.

  Next, in step A2, the wall generation unit 28 starts specifying a wall facing the outside. Specifically, in step A3, the wall generation unit 28 specifies an outer wall which is a wall facing the outside, among the basic objects PM representing the shape of the building. Then, in step A4 and step A5, for example, the wall generation unit 28 reads information from the outer wall model in which information on the outer wall type is stored, and specifies the type of the outer wall.

  When the type of the outer wall is any one of PCa, ECP, and ALC, the wall generation unit 28 proceeds to step A6, and as a wall base specification, “insulating material t = 25 LGS 50 ＠ 303 GB-R 12.5 ”is determined. In addition, when the type of the outer wall is RC, the wall generating unit 28 proceeds to step A7 and determines “insulation material t = 25 GL method GB-R 12.5” as the wall base specification. “GB-R” represents the type of board, “$ 303” represents the frame interval, “t = 25” and “12.5” represent the thickness of the board or the like.

[Generation of walls in accordance with the fire compartment of the building and the sound insulation performance of the room]

  Next, generation of a wall according to the fireproof section of the building and the sound insulation performance of the room will be described.

  When generating a wall of an arbitrary room, if the wall to be generated corresponds to a fire protection section, the wall generation unit 28 may lower the slab on the upper floor of the arbitrary room from the floor of the arbitrary room in the building. Or create a wall up to the bottom of the beam. In addition, when the wall to be generated forms a room that requires sound insulation when generating the wall, the wall generation unit 28 may control the floor of the arbitrary room in the building to the lower floor of the slab on the upper floor of the arbitrary room. Or create a wall up to the bottom of the beam.

  In steps B1 to B9 of FIG. 4, a specific method for generating a wall related to a fire protection compartment or a wall related to a room requiring sound insulation is shown.

  Specifically, first, in step B1 shown in FIG. 4, the wall generation unit 28 starts to determine specifications regarding the size of the skeleton of the LGS wall constituting the wall.

  In step B2 and step B3, the wall generation unit 28 determines whether or not the generation target wall is a wall facing a fire protection section (1 hour fire resistance). If the wall to be generated is a wall facing the fire protection section, the process proceeds to step B5 via step B2. On the other hand, if the wall to be generated is not the wall facing the fire protection section, the process proceeds to step B4 via step B3.

  In step B4, the wall generation unit 28 determines the sound insulation performance of the room formed by the generation target wall based on the information on the sound insulation of each room stored in the room requirement table RC. Here, NI = (0, 1, 2) is used as information indicating the sound insulation performance of the room. When NI = 0, it indicates that sound insulation is not required. When NI = 1, it indicates that composite sound insulation between the wall and the ceiling is necessary. When NI = 2, it indicates that sound insulation is required only by the wall.

  If the information NI = 0 or NI = 1 indicating the sound insulation performance of the room, the process proceeds to step B6. On the other hand, when the information NI = 2 representing the sound insulation performance of the room, the process proceeds to step B5.

  In step B5, the wall generation unit 28 sets so as to generate a wall up to the lower floor of the slab on the upper floor. Then, in step B7, the wall generation unit 28 extracts information on the height under the slab or under the beam stored in the structural model SM.

  In step B6, the wall generation unit 28 sets so as to generate a wall up to the top of the room. Then, in step B8, the wall generation unit 28 extracts information CH related to the height to the ceiling stored in the basic object PM.

  Then, in step B9, the wall generation unit 28 calculates the height CH under the slab or beam extracted in step B7 or the height CH up to the ceiling extracted in step B8 as the height h of the LGS wall. And Further, the wall generation unit 28 determines the specification information LGS (x) regarding the size of the skeleton of the LGS wall according to the following conditional expression (A) according to the height h of the LGS wall.

h ≦ 2.7m → LGS 50 × 45 × 0.8 (50 type)
2.7m <h ≦ 4.0m → LGS 60 × 45 × 0.8 (60 type)
4.0m <h ≦ 4.5m → LGS 90 × 45 × 0.8 (90 type)
4.5m <h ≦ 5.0m → LGS 100 × 45 × 0.8 (100 type)
(A)

  Then, the wall generation unit 28 outputs specification information LGS (x) regarding the size of the skeleton of the LGS wall. X in the LGS (x) is identification information indicating the size of the LGS wall. When x = 50, it indicates that the LGS is a 50-type LGS.

  Next, with reference to FIG. 5, a detailed process of steps B1 to B9 shown in FIG. 4 will be described. As shown in FIG. 5, the wall generation unit 28 generates a wall using functions lgs1 and lgs2 for generating an LGS wall. In FIG. 5, for simplicity of description, it is assumed that the information regarding the sound insulation of each room is information indicating whether the room is a sound insulation required room or a sound insulation unnecessary room.

  The function lgs1 for generating a wall is represented by the following equation (1). The function lgs1 is a function for determining whether the LGS wall generated in the target room reaches below the slab or the beam on the upper floor.

lgs1 = f _LGS1 (ZM, RC)
(1)

  ZM in the above equation (1) represents a zone model including information on a fire protection section. RC in the above equation (1) represents the room requirement table RC.

  As shown in FIG. 5, for each of the plurality of rooms, the wall generation unit 28 includes information on the fire prevention section stored in the zone model ZM, which is the BIM model, and information stored in the room requirement table RC (necessary for sound insulation). A function lgs1 for generating a wall of the room is calculated in accordance with the following equation (2) based on the information on whether the room is a room or a sound insulation unnecessary room).

lgs1
= F _LGS1 (1,0) = 1
= F _LGS1 (0,0) = 0
= F _LGS1 (0,1) = 1
= F _LGS1 (1,1) = 1
(2)

In the above equation (2), f _LGS1 (1,0) indicates that the target room faces the fire prevention compartment, and the target room is a room that does not require sound insulation. Also, f _LGS1 (0,0) indicates that the target room does not face the fire prevention compartment and the target room is a room that does not require sound insulation. Further, f _LGS1 (0, 1) indicates that the target room does not face the fire prevention compartment and the target room is a room requiring sound insulation. Also, f _LGS1 (1,1) indicates that the target room faces the fire prevention compartment and the target room is a room that requires sound insulation.

  Therefore, by using the above equations (1) and (2), it is determined whether the target room faces the fire prevention compartment and whether the target room is a sound insulation required room or a sound insulation unnecessary room. , The specification of the wall can be determined.

  A function lgs2 for generating a wall is represented by the following equation (3). The function lgs2 is a function for determining the specification of the height of the LGS wall.

lgs2 = f _LGS1 (lgs1, (PM, SM))
(3)

  PM in the above equation (3) represents a basic object PM representing a building to be designed. Further, SM in the above equation (3) represents a structural model.

  As illustrated in FIG. 5, the wall generation unit 28 determines, for each of the plurality of rooms, the height CH to the ceiling of the target room stored in the basic object PM and the target room stored in the structural model SM. A function lgs2 for generating a wall related to the room is calculated in accordance with the following equation (4) based on the heights h1 and h2 of the above and the calculation result of the function lgs1.

lgs2
= F _LGS2 (1, SM) = max (h1, h2)
= F _LGS2 (0, PM) = CH + 150
(4)

  As shown in the above equation (4), the calculation formula of lgs2 differs depending on the value of lgs1.

  Specifically, when lgs1 = 1, the wall generation unit 28 determines the LGS to be generated according to the following equation (5) according to whether the position of the wall to be generated is under the beam or under the slab. Determine the height of the wall.

lgs2
= F _LGS2 (1, SM) = max (h1, h2)
(5)

  On the other hand, when lgs1 = 0, the wall generation unit 28 determines the height of the LGS wall to be generated according to the following equation (6) according to the ceiling height CH of the target room.

lgs2
= F _LGS2 (0, PM) = CH + 150
(6)

  Then, according to the value output from the function lgs2, the wall generation unit 28 specifies the frame size of the LGS wall according to the above conditional expression (A) (50-type, 65-type, 90-type, and 100-type). To determine.

[Generation of wall according to water use room]

  Next, the generation of a wall according to indoor water use will be described.

  When generating a wall of an arbitrary room, the wall generation unit 28 determines the type of the material of the LGS wall according to whether or not the room is a water use room. In steps C1 to C4 of FIG. 4, a specific method of generating a wall according to whether the room is a water use room is shown.

  Specifically, first, in step C1 shown in FIG. 4, the wall generation unit 28 starts to determine the material of the skeleton of the LGS wall.

  When generating a wall of an arbitrary room in step C2, the wall generation unit 28 determines whether the room is a water use room. In the present embodiment, Hm = (0, 1) is used as the information indicating the water use room. When Hm = 0, it indicates that the room is not a water use room. When Hm = 1, it indicates that the room is a water use room.

  When the information Hm indicating the water use room is 0, the process proceeds to step C3. Then, in step C3, the wall generation unit 28 sets the material of the LGS wall to steel.

  On the other hand, when the information Hm indicating the water use room is 1, the process proceeds to step C4. Then, in step C4, the wall generation unit 28 sets the material of the LGS wall to SUS (stainless steel).

  Then, the wall generation unit 28 outputs information LGS (y) representing the material of the skeleton of the LGS wall. Y in LGS (y) is identification information indicating the material of the skeleton of the LGS wall. When y = 0, it indicates that the material of the skeleton is made of steel. When y = 1, it indicates that the skeleton material is made of SUS.

[Generation of wall according to adjacency with blowhole]

  Next, generation of a wall according to the proximity to the blow-off will be described.

  When generating a wall of an arbitrary room, the wall generation unit 28 determines the specifications of the LGS wall according to whether or not the room formed by the wall to be generated is adjacent to the blowout. Steps D1 and D2 in FIG. 6 show a specific method of generating a wall in accordance with the proximity to the blowout.

  When the room formed by the wall to be generated is not adjacent to the blow-off at step D1, the wall generation unit 28 generates a wall using the wall generation table T1 shown in FIG.

  In the wall generation table T1, the “fireproof section”, which is information on the fireproof section read from the zone model ZM, and the “sound insulation setting”, which is information on sound insulation of each room read from the room requirement table RC, are as follows. This has already been considered in B1 to B9.

  Further, in the wall generation table T1, “water use room” which is information on water use of each room read from the room requirement table RC has already been considered in steps C1 to C4.

  Therefore, the wall generation unit 28 stores the “movable partition” representing the information about the movable partition of each room, the “radiation shield” representing the information about the radiation shielding of each room, and the information about the electromagnetic wave shielding of each room in the wall generation table T1. The “electromagnetic wave shielding” represented is read from the room requirement table RC. Then, when generating the wall of each room, the wall generation unit 28 generates the wall of each room based on “movable partition”, “radiation shielding”, and “electromagnetic wave shielding” read from the room requirement table RC. Determine the wall specifications.

  Specifically, the wall generation unit 28 outputs the information LGS (x) indicating the size of the skeleton of the LGS wall output in step B9 and the information LGS (x) indicating the material of the skeleton of the LGS wall output in step C3 or step C4. y), the specification information LGS (x, y) of the LGS wall is set. The specification information LGS (x, y) of the LGS wall includes the identification information x and the identification information y, and by referring to these information, the specification regarding the skeleton of the LGS wall is determined.

  Next, when generating a wall of an arbitrary room, the wall generation unit 28, the LGS wall specification information LGS (x, y), the “movable partition” read from the room requirement table RC, and the “radiation shielding” ”And“ electromagnetic wave shielding ”, the specifications of the wall are determined.

  For example, at the bottom of the wall generation table T1, "Fireproof section: 0", "Sound insulation setting: 0", "", "Water use room: 0", "Movable partition: 0", "Radiation shielding: 0" , And the specification of the wall of the room that is “electromagnetic wave shielding: 1”, the specification of the wall is “LGS (x, y) @ 450 GB-R 12.5 + 12.5 silicon steel plate t = 0.5 10 sheets upholstery” It has become. Here, “@ 450” indicates that the frame of the LGS wall is set up at a pitch of 450 mm. Further, “GB-R 12.5 + 12.5” indicates that two gypsum boards each having a thickness of 12.5 mm are laminated and stuck. “Silicon steel sheet t = 0.5 ten sheets” means that ten silicon steel sheets having a thickness of 0.5 mm are set. Note that the assumed room in this case is an MRI room, an MRI operation room, or the like.

  As described above, by reading various information from the room requirement table RC in which information on the required performance of each room is stored, and generating the wall of the room using the various information, it is possible to appropriately and automatically generate the wall. it can.

  In step D2, when the room formed by the wall to be generated is adjacent to the blow-off at step D2, the wall generation unit 28 generates a wall using the wall generation table T2 illustrated in FIG.

  In the wall generation table T2, the “fireproof section”, which is the information on the fireproof section read from the zone model ZM, and the “sound insulation setting”, which is the information on the sound insulation of each room read from the room requirement table RC, are described in steps. This has already been considered in B1 to B9.

  Therefore, the wall generation unit 28 outputs the information LGS (x) indicating the size of the skeleton of the LGS wall output in step B9 and the information LGS (y) indicating the material of the skeleton of the LGS wall output in step C3 or step C4. , The specification information LGS (x, y) of the LGS wall is set. Next, the wall generation unit 28 determines the specification of the wall according to the specification information LGS (x, y) of the LGS wall.

  For example, at the top of the wall generation table T2, the specification of the wall of the room with "fire protection section: 1" and "sound insulation setting: 0" is shown, and the specification of the wall is "LGS (x, y)". @ 450 GB-F 21 + 21 single-sided. " Note that the assumed room in this case is an elevator shaft or the like.

[Generation of walls according to interior pillars that require finishing]

  When generating a wall of an arbitrary room, the wall generating unit 28 generates a wall according to the presence of a pillar in the room that needs finishing. For example, the wall generation unit 28 generates a wall so as to cover a pillar that needs finishing in Step E1 of FIG.

  Note that the wall generation unit 28 reflects the generated wall on the basic object PM every time a wall of an arbitrary room is generated. Thereby, the wall is included in the basic object PM of the building to be designed, and the design work of the wall of each room is appropriately supported.

  Further, the wall generation unit 28 outputs a BIM model including the generated wall and the basic object PM as a result.

  The display unit 30 displays the BIM model output from the wall generation unit 28 as a result. The display unit 30 is realized by, for example, a display.

  An architect who is a user of the design support apparatus 100 checks a BIM model including a wall object. The architect then proceeds with the design work, for example, for more detailed locations.

<Operation of Design Support Apparatus 100>

  Next, the operation of the design support apparatus 100 will be described. When the receiving unit 10 of the design support device 100 receives the input of the room requirement table RC of each room of the building to be designed, the information acquisition unit 26 stores the room requirement table RC in the basic requirement information storage unit 22. When the receiving unit 10 of the design support apparatus 100 receives an input of the basic object PM representing the shape of the building to be designed, the information acquiring unit 26 stores the basic object PM in the object storage unit 24. When the receiving unit 10 of the design support apparatus 100 receives inputs of a plurality of BIM models (for example, the structural model SM and the zone model ZM), the information acquiring unit 26 stores the plurality of BIM models in the BIM model storage unit 25. Store. Then, when receiving the instruction signal for wall generation, the design support apparatus 100 executes the design support processing routine shown in FIG.

<Design support processing routine>

  In step S100, the information acquisition unit 26 acquires the room requirement table RC stored in the basic requirement information storage unit 22.

  In step S102, the information acquisition unit 26 acquires the basic object PM stored in the object storage unit 24.

  In step S104, the information acquisition unit 26 acquires each piece of information stored in a plurality of different BIM models.

  In step S106, the wall generation unit 28 sets one room in the building to be designed.

  In step S108, the wall generation unit 28 determines the room requirement table RC acquired in step S100, the basic object PM acquired in step S102, and each information of the plurality of BIM models acquired in step S104. , The indoor wall set in step S106 is generated. Specifically, the wall generation unit 28 generates a wall located on the back side of the outer wall according to steps A1 to A7 shown in FIG. Further, the wall generation unit 28 determines the size of the LGS wall according to steps B1 to B9 shown in FIG. In addition, the wall generation unit 28 determines the material of the skeleton of the LGS wall according to steps C1 to C4 shown in FIG. Then, the wall generation unit 28 generates a wall according to steps D1 to D2 and E1 shown in FIG.

  In step S110, the wall generation unit 28 reflects the wall generated in step S108 on the basic object PM acquired in step S102.

  In step S112, the wall generation unit 28 determines whether or not the processing in steps S106 to S110 has been performed for all the rooms included in the building to be designed. When the processes in steps S106 to S110 have been performed for all the rooms included in the building to be designed, the process proceeds to step S114. On the other hand, when there is a room in which the processes of steps S106 to S110 are not performed, the process returns to step S106.

  In step S114, the wall generation unit 28 outputs the BIM model including the plurality of walls and the basic object PM obtained in step S110 as a result, and ends the design support processing routine.

  The display unit 30 displays the BIM model output from the wall generation unit 28. The architect who is the user of the design support apparatus 100 checks the BIM model to be designed and checks the walls of each room. The architect then proceeds with the design work for a more detailed location.

  As described above in detail, the design support apparatus 100 of the present embodiment generates each of the walls in the building to be designed based on the room requirement sheet. Thereby, it is possible to automatically generate a wall that satisfies the required performance of each room of the building to be designed.

  In particular, in the related art, a room requirement sheet representing the required performance of each room is extracted from a BIM model of a building including objects and attribute information, and a wall is generated using the room requirement sheet. In addition, a wall satisfying the required performance of each room can be appropriately and automatically generated.

  Further, according to the design support apparatus 100 of the present embodiment, since the work of the architect to determine the specification of the wall is reduced, the design work can be performed efficiently.

  Further, according to the design support apparatus 100 of the present embodiment, it is possible to appropriately and automatically generate a wall by generating a wall based on each piece of information acquired from a plurality of different BIM models and a room requirement sheet. it can. For example, the wall can be appropriately generated in consideration of the information on the fire prevention compartment and the information on the height of the room, which are not included in the room requirement sheet.

  The present invention is not limited to the above-described embodiment, and various modifications and applications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, information on sound insulation in each room, information on water use in each room, information on radiation shielding in each room, information on electromagnetic shielding in each room, and information on movable partitions in each room are stored in the room requirement table. Has been described as an example, but the present invention is not limited to this. For example, more or less information may be stored in the room requirement table. Specifically, the room requirement table may further include information on a fire prevention section, information on a type of an outer wall, information on a room facing a blow-off, information on a partition wall in a toilet, and the like.

  Further, in the present embodiment, the case where the wall is uniquely generated based on the predetermined condition has been described as an example, but the present invention is not limited to this. For example, when there are a plurality of candidates for the wall to be generated, each of the plurality of wall candidates may be output. In this case, the architect as the user may select a specific wall from a plurality of wall candidates. Alternatively, data on the specification of the wall selected by the architect may be collected, and the specification of the wall may be recommended (recommended) in the next wall design according to the collected data. It also collects data on the wall specifications selected by the architect, sets the collected data as learning data, and generates a trained model that outputs the wall specifications from the room requirement table for the room to be designed. You may make it. In this case, probabilities for a plurality of wall candidates are output from the trained model, and the designer who is the user selects, for example, the specification of the wall having the highest probability.

  In the above description, the mode in which the program is stored (installed) in a storage unit (not shown) in advance has been described. However, the program is recorded on any of recording media such as a CD-ROM, a DVD-ROM, and a micro SD card. It is also possible to provide in the form which has been done.
