[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0016] <Outline of the design drawing creation system> In the present embodiment, when planning the floor plan of a house such as a detached house or an apartment building, the design drawing creation system 1 omits the creation of a floor plan of the floor plan, combines multiple model parts to assemble a three-dimensional model, and creates a floor plan design drawing from the three-dimensional model.

[0017] An overview of a design drawing creation system 1 according to the present embodiment will be described with reference to Figs. 1 to 4. Fig. 1 is a perspective view of a three-dimensional model, and Fig. 2 is a plan view thereof. Fig. 3 is a diagram showing position identification points of a base plate. Fig. 4 is a diagram showing an example of a data structure of model parts. In Fig. 1, grid lines are shown by dashed lines.

[0018] The design drawing creation system 1 according to the present embodiment creates a plan view design drawing 70 shown in Fig. 2 from a three-dimensional model 60 shown in Fig. 1. As shown in Fig. 1, the three-dimensional model 60 includes a base plate 20 and a plurality of model parts 21.

[0019] The base plate 20 is, for example, a plate-like member. The base plate 20 may be formed entirely of a non-magnetic material (not shown) in order to fix the model parts 21. As shown in FIG. 3, the surface of the base plate 20 has vertical and horizontal grid lines intersecting in a lattice pattern. The grid lines extend in the X direction (horizontal direction) and the Y direction (vertical direction) and divide the position of the horizontal plane. The intersections of the X lines and the Y lines are position identification points. The position identification points are used to recognize the positions of the multiple model parts 21 arranged on the base plate 20 in the horizontal plane. To make it easier to understand, the position identification point P shown in FIG. 1 is a corner where the outer walls intersect, and coincides with P shown in FIG. 3, and its coordinates are (X, Y) = (8, 1).

[0020] The base plate 20 is connected to an output terminal such as a personal computer or tablet by a wired cable such as a USB cable, but may also be provided with a communication unit that communicates via a network. The position identification points of each of the multiple model parts 21 are transmitted to a control unit 30 (FIG. 5) described later by the USB cable or the communication unit.

[0021] As shown in FIG. 1, the model parts 21 are parts that can be installed at any position on the base plate 20. For this reason, the model parts 21 are provided with magnets and are fixed onto the magnetic model parts 21. The model parts 21 are, for example, fittings such as doors and walls, residential equipment such as kitchens and toilets, furniture such as tables and shelves, and home appliances such as refrigerators and washing machines, and are parts that make up a house. Furthermore, human models may be prepared as the model parts 21. Human models that match the family structure make floor plan planning more interesting.

[0022] A plurality of model parts 21 are provided. It is preferable that a plurality of types of model parts 21 are provided for each fitting, rather than one type for each fitting. For example, a plurality of types of stairs, such as straight stairs, return stairs, and spiral stairs, are prepared, and a plurality of types of walls with different sizes are prepared. The base plate 20 and the model parts 21 are formed to the same scale.

[0023] Each of the model parts 21 is assigned an identification number. As shown in Fig. 4, the all-parts data storage unit 10 stores information such as the type, width, depth, and height of each model part in association with a number. The all-parts data storage unit 10 stores information on all parts including model parts that are not placed on the base plate 20. To make it easier to understand, No. 1 is a door, and No. 2 and No. 3 are walls, but even if the fittings are the same, if the types or sizes are different, different identification numbers will be used, and No. 2 will be displayed as Wall 1, No. 3 as Wall 2, etc.

[0024] <Configuration of design drawing creation system> After arranging a plurality of model parts 21 on a base plate 20 to complete a three-dimensional model as shown in Fig. 1, a design drawing of a plan view is created as shown in Fig. 2. Next, a design drawing creation system for creating a design drawing of a plan view from a three-dimensional model will be described in detail with reference to Fig. 5. Fig. 5 is a block diagram of the design drawing creation system.

[0025] 5, the design drawing creation device 2 of the design drawing creation system 1 includes, as main functional components, a control unit 30, a design drawing creation machine 40, and a scanning unit 50. The processing of the control unit 30 and the design drawing creation machine 40 is performed in an output terminal such as a personal computer or a tablet, and the scanning unit 50 is performed, for example, on the base plate 20. The control unit 30 includes a part data storage unit 31, a position information storage unit 32, and a discrimination unit 33.

[0026] The parts data storage unit 31 stores the identification numbers of the multiple model parts 21 arranged on the base plate 20. Specifically, the parts data storage unit 31 extracts and stores only the identification number information of the model parts 21 arranged on the base plate 20 from the identification number information stored in the above-mentioned all parts data storage unit 10. As shown in Fig. 5, parts No. 1 indicated by reference numeral 11, No. 3 indicated by reference numeral 12, No. 5 indicated by reference numeral 13, etc. are arranged on the base plate 20, and the parts data storage unit 31 extracts and stores the identification number information of these parts 11, 12, 13, etc. from the all parts data storage unit 10.

[0027] The position information storage unit 32 stores position identification point information 22 of multiple model parts 21 arranged on the grid lines of the base plate 20. The position identification point information 22 is information on the above-mentioned position identification points, specifically, position information in the X direction and Y direction (horizontal direction). Similarly, multiple model parts 21 are arranged on the base plate 20, and the position information storage unit 32 stores position identification point information 22 for all of the model parts 21.

[0028] The identification numbers of the model parts 21 stored in the part data storage unit 31 and the position identification point information of the model parts 21 stored in the position information storage unit 32 are discriminated by the discrimination unit 33. In other words, the discrimination unit 33 identifies all information about the model parts 21 arranged on the base plate 20, and identifies the position of each model part 21.

[0029] The design drawing creation machine 40 creates a plan view design drawing 70 shown in Figure 2 based on the identification numbers of multiple parts 11, 12, 13, etc. stored in the part data storage unit 31 and the position identification point information 22 stored in the position information storage unit 32.

[0030] The scanning unit 50 is provided separately from the position identification points of the base plate 20, and is provided to accurately grasp the positions of the model parts 21. Specifically, the scanning unit 50 scans the multiple model parts 21 arranged on the base plate 20 in the X and Y directions (horizontal plane) and the Z direction (height direction), and transmits information on the multiple model parts 21 in the X and Y directions to the design drawing creating machine 40.

[0031] As described above, since the base plate 20 has position identification points provided by vertical and horizontal grid lines that intersect in a lattice pattern, it is possible to grasp the position of the model part 21. However, accurate position information of the model part 21 cannot be grasped by only this position identification point information 22. Therefore, in this embodiment, in addition to the position identification point information 22 of the base plate 20, position information in the X and Y directions (horizontal plane) and position information in the Z direction (height direction) are measured by scanning. This makes it possible to obtain accurate position information of the model part 21.

[0032] Next, a method for acquiring position information in the Z direction will be described with reference to Fig. 6 to Fig. 8. Fig. 6 is a perspective view showing a wall with a window as an example of a model part, and Fig. 7 is a diagram showing a method for fixing the window. Fig. 8 is a diagram showing a method for scanning the height position of the window. In Fig. 7 and Fig. 8, the scanning line is shown by a dashed line.

[0033] As shown in Fig. 6, the wall with a window 61 includes a wall portion 62 and a window portion 64. This wall with a window 61 is not a single component, but is composed of two components, the wall portion 62 and the window portion 64. As shown in Fig. 7, the wall portion 62 has a first magnet 63, and the window portion 64 has a second magnet 65 that is attracted to the first magnet 63 of the wall portion 62.

[0034] The first magnet 63 of the wall portion 62 and the second magnet 65 of the window portion 64 are attracted to each other, so that the windowed wall 61 is formed simply by overlapping the wall portion 62 and the window portion 64. This makes it possible to adjust the height position of the window portion 64 in an easy manner. Furthermore, since there is no need to prepare the windowed wall 61 as the model part 21, the number of parts of the model part 21 can be reduced.

[0035] 8, for example, three scanning lines are positioned in the X direction and five scanning lines are positioned in the Z direction (height direction) on the wall 62. By pressing a window 64 arranged on the wall 62, scanning lines are generated and the height position of the window 64 is detected. Also, for example, a Hall element and a reed switch may be used as the switch 66 for generating the scanning lines.

[0036] Specifically, if the window 64 is detected, it is set to "1", and if it is not detected, it is set to "0", so that from the top it is (1,1,1) (1,1,1) (1,1,1) (0,0,0) (0,0,0). In this way, it is possible to detect the height position of the window 64 using a simple method. Also, in the above-mentioned method, a method for detecting the height position of the window 64 has been described, but the above-mentioned method may also be used to detect the horizontal position of the window 64.

[0037] A modified example of a method for fixing the window 64A to the wall 62A and a method for acquiring the height Z-direction position of the window 64A will be described with reference to Fig. 9. Fig. 9 is a diagram showing another method for fixing the window and scanning the height position of the window. Also in Fig. 9, the scanning line is indicated by a dashed line.

[0038] As shown in Fig. 9, the windowed wall 61A includes a wall portion 62A and a window portion 64A fixed to the wall portion 62A. The wall portion 62A includes a hole portion 63A, and the window portion 64A includes a pin portion 65A to be inserted into the hole portion 63A. Although not shown, a plurality of holes 63A are provided on the surface of the wall portion 62A, and the window portion 64A can be inserted into any position to be positioned at any height. Furthermore, by inserting the pin portion 65A into the hole portion 63A, a scanning line is generated, whereby the position of the window portion 64A is detected.

[0039] <An example of drawing creation> A specific example of creating a design drawing of a plan view of a three-dimensional model will be described with reference to Figs.

[0040] First, prepare a base plate 20 and a plurality of model parts 21. The plurality of model parts 21 are not placed on the base plate 20. It is preferable that the land area of ​​the house and the lot of the house are stored in the base plate 20 in advance.

[0041] A plurality of model parts 21 are arranged on a base plate 20. For example, first, an exterior wall as a fitting of the model parts 21 is arranged to separate an outdoor space from an indoor space. Then, a partition wall as a fitting of the model parts 21 is arranged on the base plate 20 to separate the indoor space into a plurality of spaces such as a living room, kitchen, bathroom, washroom / dressing room, toilet, and entrance hall.

[0042] Next, fittings are selected as model parts 21 to be placed in the multiple rooms. For example, multiple types of model parts 21 are prepared for kitchens, so a desired system kitchen is placed on the base plate 20. Finally, furniture is selected and people are placed in desired locations. In this way, a three-dimensional model 60 as shown in FIG. 1 is created. This process may be carried out together with the client who is purchasing the house, or by the designer himself.

[0043] 1 is completed, the designer sends a signal to the control unit 30 using a switch provided on the base plate 20 or a transmission button on the personal computer. The design drawing creating machine 40 creates a design drawing of the plan view of FIG. 2 from the identification information and position identification point information 22 of the multiple model parts 21 arranged on the base plate 20.

[0044] Generally, it is difficult to recognize a three-dimensional view from just the plan view of the design drawing, so the floor plan is designed based on the plan view, and a three-dimensional model of the house is created after the floor plan is determined. Since the design drawing creation system 1 of this embodiment can create the plan view design drawing 70 from the three-dimensional model 60, the three-dimensional model 60 can be completed together with the customer, and customer satisfaction can be increased. Furthermore, the designer can save the trouble of creating a floor plan again after creating the three-dimensional model 60.

[0045] <Modification> In this embodiment, the part data storage unit 31 refers to the correspondence table in the all-part data storage unit 10 to estimate the model parts 21 placed on the base plate 20, but it may also be possible to estimate part information of the model parts 21 using, for example, AI technology.

[0046] Although the design drawing creation device 2 of the present embodiment is configured by a personal computer or a tablet, the present invention is not limited to such an example. For example, each functional unit of the control unit 30 may be realized by the base plate 20.

[0047] The design drawing creation device 2 of this embodiment is equipped with a scanning unit 50, but it may also be sufficient to simply detect the positions of the model parts using the position identification point information 22 of the base plate 20, and it is not necessarily required to include the scanning unit 50.

[0048] The design drawing creation process executed by the design drawing creation device 2 may be provided as a program. Such a program may be provided by being recorded on an optical medium such as a CD-ROM (Compact Disc-ROM) or a computer-readable non-transitory recording medium such as a memory card. The program may also be provided by downloading via a network.

[0049] The program according to the present invention may be one that executes processing by calling necessary modules in a predetermined sequence at a predetermined timing among program modules provided as part of a computer's operating system (OS). In this case, the program itself does not include the above modules, and executes processing in cooperation with the OS. Programs that do not include such modules may also be included in the program according to the present invention.

[0050] The program according to the present invention may be provided by being incorporated into a part of another program. In this case, the program itself does not include the modules included in the other program, and executes processing in cooperation with the other program. Such a program incorporated into another program may also be included in the program according to the present invention.

[0051] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.
