Description

[Technical Field]

[0001] The present invention relates to a technology for displaying architectural structures on a display or the like, and more specifically to a structural element display system that can separately display composite elements including a core, base, and finish. [Background technology]

[0002] Traditionally, the planning and design stages of architectural structures mainly relied on drawings created using CAD (Computer Aided Design) (hereafter simply referred to as "CAD drawings"). These CAD drawings basically only show the shape, dimensions, and location, and do not include attribute information. Therefore, if you wanted to understand detailed information about a wall, for example, you had to refer to documents such as design documents and quantity calculations in addition to the CAD drawings.

[0003] Therefore, in recent years, there have been more opportunities to use BIM (Building Information Modeling) instead of CAD. BIM uses a model that contains not only 3D shape information created on a computer, but also attribute information of the structure (materials, use, construction procedures, etc.), and can be used consistently throughout the life cycle, including not only the design stage but also the construction stage and maintenance stage.

[0004] The Ministry of Land, Infrastructure, Transport and Tourism is promoting the "Subsidized Construction BIM Acceleration Project," which subsidizes the costs of creating various BIM models, and it is expected that the number of businesses embracing BIM will increase accordingly. Furthermore, those already working on BIM have proposed various improved BIM technologies. For example, Patent Document 1 proposes a "material counting system" that sets information about the materials used for the interior and exterior of a building as color information for objects on the building's BIM model, and then tallies the quantity of objects in the BIM model that correspond to the set color information.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2023-92194 Summary of the Invention [Problem to be solved by the invention]

[0006] BIM models of buildings are sometimes created using CAD drawings. Generally, the CAD drawings are created by designers, and the BIM models are created by engineers different from the designers (hereinafter referred to as "model creators"). Designers are often not proficient in BIM operation techniques, while model creators are often not well versed in specialized knowledge about buildings. As a result, the BIM objects (composing the BIM model) created by the model creators are checked by the designers using methods other than BIM, and the BIM objects are modified based on the designers' correction instructions.

[0007] Designers have been checking BIM objects using viewers that simply display them, rather than directly operating them. Viewers for viewing BIM objects are already available on the market, such as Autodesk's "Forge Viewer." However, as mentioned above, designers are often not familiar with BIM operations and are therefore unable to fully utilize Forge Viewers and similar tools. Sharing BIM through the Docs browser is also an option, but its functionality is limited, making it difficult to say that it is a sufficient method for checking BIM objects.

[0008] Furthermore, conventional technologies such as the Forge Viewer and the material calculation system in Patent Document 1 were unable to properly display the elements that designers wanted to check. In particular, composite elements, including the core, base, and finish, could not be displayed separately. Moreover, although the relationship between rooms and objects in a building is close in design, the two are not linked in the BIM model, so it was not possible to display BIM objects such as composite elements for each room, for example.

[0009] The object of the present invention is to solve the problems of the prior art, that is, to provide a structural element display system that allows designers to display BIM objects for each composite element and for each room when checking. [Means for solving the problem]

[0010] This invention was created by focusing on the idea of ​​associating BIM objects with rooms and displaying each composite element (core, base, and finish) in a different color, and is based on an entirely new idea.

[0011] The structural element display system of the present invention displays structural elements contained in a structure, such as walls, floors, and ceilings, that make up a room. The system includes an object storage means, an element designation means, and an object display control means. These structural elements include at least a "core," a "base," and a "finish." The object storage means stores BIM objects generated for each structural element, and the element designation means designates a structural element through an operator's operation. The object display control means reads a BIM object associated with a structural element designated by the element designation means from the object storage means and displays the read BIM object on the display means. The element designation means can designate both a room and a structural element. The object display control means reads a BIM object from the object storage means based on a room identifier corresponding to the designated room and element information corresponding to the designated structural element, and displays the BIM object on the display means together with the room and at the planned position within the room in a display color corresponding to the element information of the read BIM object.

[0012] The structural element display system of the present invention can also be configured so that BIM objects have "material information" that identifies the material of the structural element. In this case, the element specification means is capable of specifying the material. The object display control means reads out a BIM object having material information corresponding to the specified material from the object storage means, and displays the BIM object on the display means in a display color that identifies the material information of the read BIM object.

[0013] The structural element display system of the present invention can also be configured so that the BIM object has "structure information" that identifies the structure. In this case, the element designation means can designate the structure. The object display control means reads out and displays a BIM object having structure information corresponding to the designated structure from the object storage means.

[0014] The structural element display system of the present invention can also be configured so that the BIM object has "floor information" that identifies the floor. In this case, the element designation means can designate the floor. The object display control means reads out the BIM object having the floor information corresponding to the designated floor from the object storage means and displays it.

[0015] The structural element display system of the present invention may further include an object registration means and a modification information registration means. The object registration means is a means for registering a BIM object in the object storage means, and the modification information registration means is a means for associating modification information for the BIM object with the BIM object and registering it in the object storage means. In this case, the object display control means displays the BIM object related to the modification information in a "modification display color" indicating that a modification has been made. Then, when the BIM object modified in accordance with the modification information is registered in the object storage means, the object display control means hides the modification display color.

[0016] The structural element display system of the present invention may further comprise an object room identifier change means for changing the room identifier (unique ID) to which the object belongs. This object room identifier change means is a means for changing the room identifier of the BIM object displayed on the display means to a room identifier different from the displayed room, by an operator operation. In this case, the modification information registration means registers the destination room identifier as modification information, and associates it with the BIM object moved by the object room identifier change means. [Effects of the Invention]

[0017] The structural element display system of the present invention has the following advantages. (1) It is possible to display each room individually and with different display colors for each composite element (core, base, finish). As a result, designers can check BIM objects more easily than before. (2) By providing a means for registering correction information, the model creator can easily and quickly check the results of the designer's checks, and the designer can easily and quickly check the results of the model creator's corrections. As a result, smooth communication between the model creator and the designer can be achieved, and more appropriate BIM objects can be created. (3) Designers can check BIM objects without having to learn how to operate BIM and without needing special licenses. (4) It is also possible to calculate the quantity by room and by composite element (core, base, finish). [Brief explanation of the drawings]

FIG. [Figure 8] FIG. 2 is a flowchart showing the main processing flow of the structural element display system of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0019] An example of an embodiment of the structural element display system of the present invention will be described with reference to the drawings. Figure 1 is a model diagram showing an overview of the structural element display system of the present invention. As shown in this figure, the structural element display system of the present invention can narrow down and display the objects desired by the viewer by querying a BIM model on the cloud, for example. Note that this BIM model is composed of individual BIM models (hereinafter referred to as "BIM objects") related to the wide variety of objects that make up a building.

[0020] The requirements for narrowing down objects (hereinafter referred to as "narrowing down requirements") include the "rooms" and "floors" within a building, the "structure (floors, walls, ceilings, doors, windows, etc.)," ​​the "structural elements (core, base, finish, etc.)," ​​and the "materials" of the structural elements. For example, if a viewer specifies a living room (room) and a finish (structural element) as the narrowing down requirements, the viewer's display means (such as a monitor) will display the living room finish, and the finish will be displayed in a color that identifies the type of object element. Therefore, even if two types of structural elements, such as a finish and a wall core, are specified, the finish and the wall core will be displayed in different colors, allowing the viewer to distinguish between them.

[0021] 2 is a block diagram showing the main components of the structural element display system 100 of the present invention. As shown in this figure, the structural element display system 100 of the present invention is configured to include element designation means 101, object display control means 102, and object storage means 103, and can also be configured to include object registration means 104, correction information registration means 105, object room identifier change means 106, display means 107, tallying means 108, etc.

[0022] Among the main components constituting the structural element display system 100, the element designation means 101, object display control means 102, object registration means 104, revision information registration means 105, object room identifier change means 106, and tallying means 108 can be manufactured as dedicated components, or general-purpose computers can be used. That is, each computer performs its own specific processing by executing a predetermined program. This computer includes a processor such as a CPU, memory such as ROM and RAM, input means such as a mouse and keyboard, and a display. It executes the processing according to the predetermined program and can be configured as a personal computer (PC), a server, a tablet PC such as an iPad (registered trademark), or a mobile device such as a smartphone. When using a computer including a display, the display can also be used as the display means 107.

[0023] The object storage means 103 can be a storage device such as a personal computer, or can be built in a database server. When built in a database server, it can be placed on a local network (LAN: Local Area Network), or can be a cloud server that stores data via the Internet.

[0024] As mentioned above, designers who create CAD drawings are often not familiar with BIM operation techniques. Therefore, as shown in Figure 2, the designer side is provided with only the means for displaying BIM objects (element specification means 101, object display control means 102, display means 107) and the means for handling information for modifying BIM objects (hereinafter simply referred to as "modification information") (modification information registration means 105 and object room identifier change means 106), while the object registration means 104 that directly processes BIM objects is provided on the model creator (the person who creates the BIM model) side.

[0025] Below, each of the main elements that make up the structural element display system 100 of the present invention will be described in detail.

[0026] (Object storage means and object registration means) The object storage means 103 is a means for storing BIM objects. The object registration means 104 is a means for an operator (particularly a model creator) to register BIM objects in the object storage means 103 by operating a pointing device (such as a mouse, touch panel, pen tablet, touchpad, trackpad, or trackball), a keyboard, or the like.

[0027] A BIM object is generated for each structural element, such as the core, base, or finish, and is assigned information that identifies that structural element (hereinafter simply referred to as "element information") and information that identifies the room in which it will be installed (hereinafter simply referred to as "room identifier"). Furthermore, BIM objects can also be assigned information that identifies the floor on which they will be installed (hereinafter simply referred to as "floor information"), information that identifies structural elements such as floors, walls, and ceilings (hereinafter simply referred to as "structural information"), and information that identifies the materials of the structural elements (hereinafter simply referred to as "material information").

[0028] The object storage means 103 also stores the display color used to display BIM objects. This display color is set to a different color to identify the type of object element. Since the type of object cannot be predicted in advance, the display color of the object is set automatically. By matching the list color containing the object element name with the object element color displayed in 3D, there is no need to set a specific color for the object in advance, and it is possible to identify it. This makes it possible to understand which structural element the BIM object represents or what material it is made of based on the display color.

[0029] (Element specification method) The element designation means 101 is a means by which an operator (particularly a designer) designates narrowing-down requirements by operating a pointing device, keyboard, etc. For example, in the case of Fig. 3, rooms A, B, and C are designated as narrowing-down requirements, with "wall" designated as the structure and "wall core" designated as the structural element. In the case of Fig. 4, rooms A, B, and C are designated as narrowing-down requirements, with "door" and "window" designated as the structure.

[0030] In this way, the element designation means 101 can designate a room and a structural element as a refinement requirement. Furthermore, when structure information is assigned to a BIM object, the element designation means 101 can designate a structure as a refinement requirement. Similarly, when floor information is assigned to a BIM object, the element designation means 101 can designate a floor as a refinement requirement, and when material information is assigned to a BIM object, the element designation means 101 can designate the material of a structural element as a refinement requirement.

[0031] (Object display control means) The object display control means 102 is a means for reading out BIM objects that match the narrowing down requirements specified by the element specification means 101 from the object storage means 103, and displaying the read-out BIM objects on a display means 107 such as a display.

[0032] For example, in the case of Fig. 5, only the "wall core" of the "walls" installed in rooms A, B, and C specified by the element specifying means 101 is displayed. In this case, the wall core is displayed together with rooms A, B, and C, and at the planned position in each room, and is further displayed in a display color that identifies the type of object. Similarly, in the case of Fig. 6, the "doors" installed in rooms A, B, and C specified by the element specifying means 101 are displayed.

[0033] In this way, the object display control means 102 displays BIM objects that match the narrowing requirements specified by the element specification means 101, so viewers (especially designers) can check, for example, each structural element individually, that is, they can check the suitability of the BIM object for each structural element. Also, even if two types of structural elements, such as a wall core and a base, are displayed, the wall core and the base are displayed in different colors, so viewers can distinguish between them.

[0034] (Method of calculation) The aggregation means 108 is a means for counting the quantity of BIM objects that match the narrowing requirements specified by the element specification means 101. For example, in the case of Fig. 5, the quantity (area) of "walls" is calculated for each BIM object, and in the case of Fig. 6, the quantity (number) of doors is calculated.

[0035] (Means for registering correction information) The correction information registration means 105 is a means by which an operator (particularly a designer) assigns correction information to a BIM object by operating a pointing device, keyboard, etc. For example, when a designer checks a BIM object displayed on the display means 107 and finds an error, the designer indicates the content to be corrected (i.e., correction information) by specifying (clicking) the object, selecting from a list, entering text, etc. The correction information entered by the designer is then associated with the corresponding BIM object and stored in the object storage means 103.

[0036] The object display control means 102 displays the BIM object associated with the modification information on the display means 107 in a special display color, that is, a display color indicating that there is something that needs to be modified (hereinafter referred to as "modification display color"). This modification display color is set to a color that particularly attracts attention, such as yellow.

[0037] An operator (especially a model creator) who has confirmed the BIM object with the modified display color checks the modification information and automatically modifies the BIM object in accordance with the modification information by executing a plug-in. Then, when the BIM object in question is modified, the object display control means 102 hides the modified display color and changes it to, for example, the original display color set for the structural element.

[0038] (Object room identifier change means) The object room identifier change means 106 is a means by which an operator (particularly, a designer) changes the BIM object displayed on the display means 107 to belong to a room (room identifier) ​​different from the displayed room by operating a pointing device, keyboard, or the like. If the displayed room is incorrect, the room identifier is changed using the object room identifier change means 106 so that the room belongs to a different (correct) room. For example, in the case of Figure 7, an instruction is given to change the "floor" installed in room A to room B. The BIM object instructed to change to room B by the object room identifier change means 106 is assigned correction information indicating "room change" by the correction information registration means 105. Once the correction information is assigned, the BIM object is associated with the correction information (room change) and stored in the object storage means 103, and is displayed on the display means 107 with a correction display color. The operator (particularly, a model creator) then corrects the BIM object in question (so that it has the correct room identifier) ​​according to the correction information, and the correction display color is then hidden.

[0039] (Processing flow) The main processing of the structural element display system 100 of the present invention will be described in detail below with reference to Fig. 8. Fig. 8 is a flow diagram showing an example of the flow of the main processing of the structural element display system 100, with the processing to be executed shown in the center column, information required for that processing shown in the left column, and information resulting from that processing shown in the right column.

[0040] When a BIM object is created by a model creator, the BIM object is registered in the object storage means 103 using the object registration means 104 (Step 201 in Fig. 8). This BIM object is assigned element information and a room identifier, as well as floor information, structure information, and material information.

[0041] When the designer specifies the narrowing down requirements using the element specification means 101 (Step 202 in Figure 8), the object display control means 102 reads out BIM objects that match the narrowing down requirements from the object storage means 103 (Step 203 in Figure 8), and displays the read out BIM objects on the display means 107 (Step 204 in Figure 8).

[0042] The designer checks the appropriateness of the BIM object while visually checking the display means 107 on which the desired BIM object is displayed, and inputs correction information if an error is found in the BIM object (Step 205 in Fig. 8). Then, the correction information is associated with the corresponding BIM object and stored in the object storage means 103, and the object display control means 102 displays the BIM object associated with the correction information on the display means 107 in a correction display color (Step 206 in Fig. 8).

[0043] When the model creator checks the BIM object with the modified display color, he / she modifies the BIM object in accordance with the modification information (Step 207 in FIG. 8). Then, when the BIM object is modified, the object display control means 102 hides the modified display color (Step 208 in FIG. 8) and changes it to, for example, the original display color set for the structural element. [Industrial Applicability]

[0044] The structural element display system of the present invention can be effectively applied not only to buildings, but also to civil engineering structures, electrical equipment, etc. The present invention makes it possible to consistently manage the life cycle of architectural structures from design to maintenance, which means that it is possible to provide an appropriate social infrastructure. Considering this, the present invention can be said to be not only applicable industrially but also to be expected to make a great contribution to society. [Explanation of symbols]
