Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an architectural model production system, an architectural model production program, and an architectural model for producing a building obtained by scaling a real building at a predetermined scale factor.
[0002]
[Prior art]
For example, when a single-family house is to be built, it is advanced while confirming in advance a plan view of the structure of the house in a drawing. In the case of a two-story house, in addition to the floor plan of the first floor part and the floor plan of the first floor part, the structure of the house can be confirmed in a state where fittings are also appropriately arranged. In addition, the configuration of the outer groove is similarly confirmed by a plan view. In some cases, there is also a method of displaying the exterior and interior of a house in a three-dimensional manner.
[0003]
However, it is difficult to see the actual structure from such a drawing. Therefore, various systems for producing an architectural model in which an actual house (building) is scaled at a predetermined scale factor are known (for example, Patent Document 1 below). Such an architectural model is provided as a service to a housing contractor.
[0004]
[Patent Document 1]
Patent No. 2811878 [0005]
[Problems to be solved by the invention]
The subject of the present invention is as follows. A method of cutting out a model member for manufacturing an architectural model by printing out a drawing using normal CAD software for building and pasting the drawing on a board can be considered. However, since the structure of the model member in manufacturing an architectural model is different from an actual building, it is difficult to obtain a drawing for manufacturing the model member. For example, in the case of an actual house, the outer wall member and the inner wall member are composed of different members, but considering the scale factor, in the case of an architectural model, it is not necessary to actually make it faithfully, and will be omitted. This is preferable in terms of cost. Moreover, even if it is actually a shaft construction method, it takes time to assemble to reproduce a complex structure shaft with an architectural model.
[0006]
Therefore, in consideration of the above points, it is possible to rationally perform a series of processes from inputting necessary data to obtaining a model member constituting the architectural model when constructing a system for manufacturing an architectural model. And reducing costs. In particular, architectural models are often provided free of charge to employers, so it is important to solve this problem in order to reduce the cost burden on real estate brokers and the like. That is, the present invention has been made in view of the above circumstances, and its object is to provide an architectural model manufacturing system and an architectural model manufacturing program that can rationalize the process of manufacturing an architectural model and reduce the cost. It is.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, an architectural model production system according to the present invention is:
An architectural model production system for producing an architectural model obtained by scaling an actual building at a predetermined scale factor,
A means for creating a model drawing of the scale at a predetermined scale based on the input drafting data for the architectural model;
Based on this model production drawing, means for calculating the dimensions of individual model members,
And a means for creating a drawing for cutting a model member to which a cutter cutting line is added based on the calculated dimensions.
[0008]
The functions and effects of the architectural model production system with this configuration are as follows. First, drafting data for a building model is input, and a model drawing for working at a predetermined scale is created. This is different from the drawings for an actual building, in which unnecessary portions as models are removed. Such drawings include, for example, an elevation from four directions, a first floor plan, a second floor plan, and a cabin plan. Next, based on this model production drawing, the dimension of each model member is automatically calculated, and a model member cutting drawing to which a cutter cutting line is added is created. This model production drawing, calculation of model member dimensions, and creation of model member cutting drawings can be performed by the function of a computer program. Moreover, when making it cut with a cutter, the data from the model member cutting drawing can be used. In this way, a series of processes from inputting drafting data to creating a drawing for cutting a model member can be rationally performed. As a result, it is possible to provide an architectural model production system capable of rationally performing the architectural model production process and suppressing the cost.
[0009]
As an embodiment of the present invention, means for externally outputting the model production drawing and the model member cutting drawing,
From the board on which the drawing for cutting the model member that has been output externally is pasted, a cutter that cuts each model member along the cutter cutting line, and
An example is a model in which an architectural model is manufactured by assembling the cut boards.
[0010]
The drawing for cutting the model member is output in a hard copy form on paper or the like by an external output means (for example, a laser printer). This model member cutting drawing is attached to a board (for example, styrene board) constituting the model member. Then, using a cutter, the board is cut along the cutter cutting line. Thereby, each model member can be obtained. Thus, by outputting the drawing for cutting the model member on which the cutter cutting line is printed, it is possible to easily perform the cutting with the cutter.
[0011]
As a preferred embodiment of the present invention, there is one provided with an index generating means for adding a cutting reference index to the model member cutting drawing.
[0012]
By adding this cutting reference index to the drawing for cutting the model member and printing it, it can be used as a reference when cutting with a cutter. Thereby, the cutting | disconnection by a cutter can be performed with sufficient precision.
[0013]
As a preferred embodiment of the present invention, among the model members, when the wall surface member and the wall surface member are abutted at an angle of θ, the end surface of each wall surface member at the abutting position is θ / 2 with respect to the wall surface. And those that are cut by the cutter.
[0014]
When the wall member is formed by cutting the board, the butt is usually as shown in FIG. If it does so, the end surface of a board will be exposed in a butt | matching position, and the external appearance of an architectural model will fall. Therefore, by setting the end face of the wall member to θ / 2 as described above, it is not necessary to expose the end face as shown in FIG. 6B as an example. Therefore, it can be set as a good-looking architectural model.
[0015]
As another preferred embodiment of the present invention, when the roof member and the roof member are abutted at an angle of θ among the model members, the end surfaces of the roof members at the abutting position are θ / 2 with respect to the wall surface. The thing cut | disconnected by the said cutter is mention | raise | lifted.
[0016]
The butt of the roof member is the same as the butt of the wall surface member. By setting the end face of the roof member to θ / 2 with respect to the wall surface, it is not necessary to expose the end face to the external appearance, and it is possible to obtain a building model with good appearance.
[0017]
As yet another preferred embodiment of the present invention, an automatic numbering means for automatically assigning a part number to each model member is provided, and the part number is printed on the model member cutting drawing. Things can be raised.
[0018]
By printing such a part number, it can be used for collation with a counterpart part when assembling the model member, and the assembling work can be facilitated.
[0019]
The architectural model production program for constructing the architectural model production system according to the present invention is:
Based on the input drafting data for the architectural model, a process of creating a model drawing of the scale at a predetermined scale,
Based on this model production drawing, means for calculating the dimensions of individual model members,
Based on the calculated dimensions, the computer is caused to execute a process of creating a drawing for cutting a model member to which a cutter cutting line is added. The operations and effects of this configuration are as described above.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of an architectural model production system according to the present invention will be described with reference to the drawings. First, the configuration of the architectural model production system will be described with reference to FIG. This system is a system for producing a housing model (corresponding to an architectural model) in which an actual house (corresponding to a building) is scaled at a predetermined scale factor (for example, 1/50). The model members that make up the house model have styrene board as the main member, and after pasting the printed drawing using the architectural model production system on the surface of this styrene board, each model member using a predetermined cutting machine Is obtained by cutting from a styrene board. An architectural model is produced by assembling this model member.
[0021]
As shown in FIG. 1, an architectural CAD software 1 is configured as the core of the system, and the CAD software 1 is installed in a personal computer and used. That is, a function for manufacturing a model is added to general architectural CAD software. This CAD software can be configured based on, for example, MADRIC 2000 manufactured by CPI Corporation. FIG. 1 illustrates only typical functions of the CAD software 1. The data input unit 10 inputs drawing data for a model. For example, site data, floor data, inner / outer wall data, pillar / stairs data, joinery data, ceiling data, hut data, and roof data are input. The scale setting unit 11 sets the scale of the architectural model to be manufactured. Although the scale can be set as appropriate, in this embodiment, 1/50 is set.
[0022]
The model making action drawing creating means 12 has a function of making a model making action drawing having a set scale magnification (1/50) based on the input drawing data. This model production drawing is a drawing specialized for a model unlike an actual architectural drawing, and the shape and the like of a portion unnecessary as a model are removed by filtering. For example, even when an actual house is constructed by a shaft construction method, a shaft assembly portion is unnecessary as a model, and is therefore removed from the model manufacturing drawing. This model production drawing includes, for example, a plan view, a detailed plan view, an elevation view (each side of east, west, south, and north), a development view, a rectangular view, a ceiling plan view, a cabin plan view, and a roof plan view.
[0023]
The automatic numbering means 13 has a function of automatically assigning a part number (or identification code) to each model member. Further, this part number can be printed on a model production drawing or a model member cutting drawing, and can be used as a reference when assembling a model member cut by the cutting machine 20. Of course, the part number may be used for normal use.
[0024]
The dimension calculating means 14 has a function of calculating the dimension of each model member based on the model manufacturing action drawing. This dimension data can be used as data for moving the blade when cutting the styrene board by the cutting machine 20. The model member cutting drawing creating means 15 creates a model member cutting drawing based on the model production drawing and the calculated dimension data. A cutting line cut by a cutter is added to this drawing.
[0025]
The mark adding means 16 adds a mark (cutting reference index, for example, a register mark) to the model member cutting drawing. This mark can be used as a reference when cutting with the cutting machine 20.
[0026]
The monitor 2 can be used for confirming a drawing produced by the CAD software 1 on a monitor screen, confirmation when inputting various data, and the like. The printer 4 is used for printing a model production drawing and a model member cutting drawing. For example, a color laser printer is preferably used as the printer 4. As the cutting machine 20, for example, a sample cutter can be used. However, the present invention is not limited to this, and other cutters or a plurality of types of cutters may be used.
[0027]
<Housing model production concept>
Next, the concept for producing a house model will be described with reference to FIG. The housing model can be roughly divided into a housing body and an outer groove. As shown in FIG. 5, the model members constituting the house model include a roof member, a ceiling member, an outer wall member (corresponding to a wall surface member), an inner wall member (corresponding to a wall surface member), a staircase member, a column / beam member, and a fitting member. Can be divided into floor members. The outer groove is made of site material.
[0028]
As shown in FIG. 5, the roof member, the wall surface member, and the like need an appropriate pattern on the surface. Therefore, the printer 4 prints the necessary color and pattern on the model member cutting drawing. For the outer wall member and the inner wall member, the butted portion is cut at 45 °. This is to improve the appearance of the mating part (described later). For the staircase members, staircases are manufactured from styrofoam blocks (described later). Columns and beams are manufactured by cutting the matching shafts 90 ° to the required dimensions. However, this is limited to Japanese-style rooms.
[0029]
As for the joinery members, not all of them are manufactured according to the drawing for cutting the model member, but commercially available products for models such as windows, entrance doors, and doors are used. Of course, these windows, doors, and the like may be obtained by printing on a drawing, but a higher quality feeling can be obtained by using commercially available products. Use commercially available models for outer grooves such as trees and hedges.
[0030]
In FIG. 5, consideration points for the CAD software (CG2000) work will be briefly described. For the roof member, a roof plan is output based on the function of the model production drawing creating means 12, and then the dimensions of the roof member are calculated based on the function of the dimension calculating means 14. For the ceiling member, the ceiling plan is similarly output, and the dimensions of the ceiling member are calculated. The outer wall member outputs an elevation and calculates dimensions. The other dimension calculation procedures are the same, and are shown in FIG. This dimension is used for adding a cutter cutting line as data and printing the cutter cutting line on the drawing. The calculated dimension data can also be used as data when moving the cutter when cutting the cutter cutting line by the cutting machine 20.
[0031]
FIG. 4 shows a system flow for outputting the model drawing of the house model. First, the site outline and plan map are created by performing the property summary process by inputting the drafting data for the model (site, floor, inner wall, outer wall, pillar, stairs, joinery, ceiling, hut, roof data). The From this site map and plan map, a layout map, a plan view, a detailed plan view, and a roof plan are obtained. In the same manner, a house figure, a rectangular figure, a ceiling figure, a developed figure, and an elevation figure are obtained. Each of these drawings is the basis for calculating the dimensions of the individual model members.
[0032]
Next, the matching of the wall surface members will be described with reference to FIG. FIG. 6A shows the butt of the wall member in the present invention, and FIG. 6B shows the conventional butt. In the conventional type, the end surface of the wall surface member is not subjected to special treatment, and the end surface of the other wall surface member 30 is applied to the inner surface side of one wall surface member 31 and bonded thereto by adhesion. In this butting method, the end face of one wall surface member 31 is exposed to the outside. Therefore, the exposed portion has a poor appearance and it is necessary to cover the exposed portion. On the other hand, in the butting according to the present invention, the end surface of one wall surface member 33 and the end surface of the other wall surface member 32 are both cut at 45 ° to the wall surface. Thereby, since the end surface of any wall surface member 32 and 33 is not exposed in a butt | matching position, it can improve appearance. In the example of (a), since the butt angle is θ = 90 °, the angle of the end face is θ / 2 = 45 °. The same can be considered when θ is not 90 °.
[0033]
Next, the matching of the roof members will be described with reference to FIG. FIG. 7A shows a joining method according to the present invention, and FIG. 7B shows a conventional joining method. In the conventional type, the notch 35a is formed in the central portion of the roof member 35 and folded, but this also has a drawback that the appearance is deteriorated. Therefore, as shown in (a), when the butt angle is θ, the butt end surface 36a (37a) between the roof members 36 and 37 can be set to θ / 2 to improve the appearance of the butt portion. .
[0034]
<Configuration of staircase members>
Next, the structure of the staircase member will be described with reference to FIG. 8 (first embodiment) and FIG. 9 (second embodiment).
[0035]
First, the first embodiment will be described. First, an elevation view of a staircase as shown in FIG. 40 is produced by the CAD software 1, and this elevation view is printed out and pasted on cardboard. Since the shape of the elevation view is necessary on both sides in the width direction, cut two. Next, styrofoam (a kind of hard foam material) is cut into a dice shape (cubic shape) according to the external dimensions of the staircase. A double-sided tape is affixed to the back surface of the cardboard 42, and both sheets are affixed to the opposing surfaces of the styrofoam 41. Next, a cardboard can be used as a mold and cut with a hot wire cutter to produce a staircase member.
[0036]
Next, a second embodiment will be described. By CAD software, the planar shape of the staircase portion is output from the plan view. This is indicated by reference numeral 45. This is affixed to a beige 5 mm thick styrene paper and cut along the line. Thereby, as shown in FIG. 44, the step portion of the staircase member can be manufactured. Further, the side shape of the staircase is created by drawing with the CAD software 1. This is printed out and affixed to a 1 mm thick styrene board 43 and cut according to the side shape.
[0037]
<Model production procedure>
The procedure for manufacturing a house model is shown in the flowchart of FIG. 2, and the process for manufacturing the house model will be described based on this. FIG. 3 shows a process list when manufacturing a house model.
[0038]
First, model drawing data is input (# 1 in FIG. 2). The drafting data is site data, floor data, etc. as already described (see FIG. 3). Then, the scale magnification is set to 1/50, and a drawing of the model manufacturing action is created (# 2). At this time, portions not related to model production are filtered and removed. It is preferable that the part number given by the automatic numbering means is given to this model manufacturing action drawing. This model production drawing is output by the printer 4 (# 3). As already described, these are the drawings shown in FIG. The output drawings are shown as an example in FIGS. 12 to 14 (elevation, detailed plan view 1F, detailed plan view 2F). Other drawings are created in the same manner.
[0039]
Next, a drawing for cutting the model member is created and output by the printer (# 4). The output drawings are shown as an example in FIGS. A cutting line L for cutting with a cutter is printed on the model member cutting drawing. In addition, a part number (not shown) is printed at an appropriate location on the model member cutting drawing. 15 and 16 are obtained by adding a cutting line L to the elevation view. As can be seen from this figure, the outer wall portion is one drawing in which the first floor and the second floor are connected. The same applies to the other elevation views. FIG. 17 shows an example of a drawing for cutting a model member used as a wall member for partitioning a room and a room from a room. FIG. 17 shows four examples as an example, but the others are the same. About each member of FIG. 17, the outermost part becomes a cutting line. In addition, since the roof member is viewed from an oblique direction in an elevation view or a plan view, a drawing developed so as to have a correct dimension is created and output.
[0040]
FIG. 10 and FIG. 11 explain the manufacturing procedure of each model member individually. In the description, CG2000 indicates CAD software.
[0041]
Next, the printed drawing for cutting the model member is used as a pattern and attached to the styrene board (# 5). This styrene board is set in the cutting machine 20 and cut based on the cutting data (# 6). In addition, since a reference is necessary when cutting with the cutting machine 20, it is preferable to print what becomes a cutting reference index (for example, a register mark of “+” mark) on the drawing for cutting the model member. Data for cutting (based on the above-described dimension data) is also preferably created as data for this reference. Thereby, setting of a styrene board can be performed easily.
[0042]
Next, each cut model member is assembled while being bonded (# 7). At this time, the model members are cut into shapes of individual model members from the drawing for cutting the model members, and it may not be immediately understood how to assemble them when the number of model members is large. Therefore, it can be assembled with reference to the model manufacturing action drawing output in step # 3. Alternatively, a dedicated drawing for explaining the assembly method may be created and printed out. As another method, a part number may be printed on a portion to be joined in an inconspicuous form, and a model member on which the corresponding part number is printed may be bonded. In other words, the assembly may be carried out using part numbers as a guide.
[0043]
The joinery may be manufactured by the cutting machine 20 based on the drawings, and commercially available products such as entrances and windows may be used. In the case of a Japanese-style room, pillars are provided at the four corners of the room so as to be exposed to the outside. Therefore, a match tree can be used to express this.
[0044]
FIG. 18 shows a schematic procedure for assembling a styrene board. FIG. 19 is a diagram showing a completed state. FIG. 20 is a diagram illustrating a state in which a completed roof portion is removed. By removing the roof part, you can see the internal room structure. If the ceiling on the second floor is removed, the interior structure of the first floor can be seen.
[0045]
<Another embodiment>
In the present embodiment, a single-family house model has been described. However, the present invention is not limited to this, and the present invention can also be applied to other buildings.
In this embodiment, although it cuts along a cutter cutting line with a cutting machine, an operator may cut with an appropriate cutter manually.
[0046]
In this embodiment, a styrene board is used as the board, but the present invention is not limited to this, and other types may be used.
