Description

3-D graphic data producing system and the method using 2-dimensional graphic drawings}

The present invention relates to a three-dimensional graphic data production system using a two-dimensional graphic drawing and a method for manufacturing the same, and more specifically, to a three-dimensional shape using a two-dimensional graphic drawing such as a CAD drawing created by a conventional two-dimensional design method. The present invention relates to a three-dimensional graphic data production system for producing a logical three-dimensional shape by receiving additional information and to a physical three-dimensional shape, and a method of manufacturing the same.

Conventional methods for manufacturing three-dimensional shapes include a method in which an operator directly inputs three-dimensional coordinates using a three-dimensional CAD or a modeling tool and automatically extracts three-dimensional coordinates using a three-dimensional scanner. 1 shows a flowchart of this conventional method. That is, before shaping the 3D object, information about the object (object characteristics, relations between objects, etc.) is input separately using a specific program to generate object information, and coordinate values (shape coordinates) for each generated object information ) Is input by the operator using a specific program, and finally adopts a method of deriving a three-dimensional shape through an output device. Specifically, in the conventional method, a three-dimensional shape is distinguished and combined by elements. (For example, if you want to separate the elements of a specific part and combine them as a whole, in the mechanical structure where several elements are combined), separate and distinguish the elements by grouping coordinate values constituting the elements. Then, the element corresponding to the coordinate value is visualized on a separate display device (monitor, etc.) and used for a certain purpose (output, Modifications, etc.) imply a fundamental technical limitation that the 3D data must be used in some way.

That is, when designing a structure such as a building, such a method using the conventional three-dimensional CAD and the like, it is impossible to use the two-dimensional design drawings (normal design drawings) that have been used for decades in design services, etc. It is necessary to fundamentally change the design approach that is easy and accessible, and from the designer's point of view, the work of fundamentally changing the design method creates a lot of confusion and the burden of acquiring a new three-dimensional design method. .

In addition, in recent years, in the case of high-rise, complicated, and large-scale buildings, when the three-dimensional shape of each element constituting the building is independently processed due to the complexity of the building, the processing takes a great deal of time. If the number of elements is large, the same elements (because each element has a separate position value, but the same elements can be distinguished as different elements) are overlapped with each other, resulting in overlapping construction (separation and combination work) for the same elements. In addition, the worker (designer) also has an inherent limitation that it is not easy to identify where each component belongs, and that the design work by the three-dimensional shape is not easy, and the overall shape of the building It must be firmly organized in each worker's head, Because it allows the completion of the three-dimensional shape of, work to complete the design and many workers are shaping the design work itself is not real choice but to participate in the design work of one of the buildings in three dimensions it is a situation that is hardly used.

In other words, in the design of buildings, it is necessary to spend a lot of time and derive a three-dimensional shape only when it costs a lot of money. Due to this problem, the contractor or work manager who manufactures a real building with two-dimensional design drawings is required to separate the three-dimensional shape (three-dimensional shape) by the operator. There is a problem in that the design drawings are reconfigured, and cumbersome re-editing and changing operations are required according to the purpose.

Therefore, in the design of buildings, etc., the problems of the conventional three-dimensional shape manufacturing method are improved, and a system for easily and efficiently using the two-dimensional design drawings to produce the object in three dimensions, and using the two-dimensional design drawings three-dimensional There is an urgent need for a method that can be changed.

The present invention is to solve the above problems,

The object of the present invention is to use the existing two-dimensional drawings produced by the two-dimensional design method that has been traditionally used as it is, using a two-dimensional graphic drawing that is easy for designers to access without changing the existing design method and concept 3 The present invention provides a dimensional graphic data production system and a method of manufacturing the same.

Another object of the present invention is to create a three-dimensional graphic shape that can be accessed logically and stepwise by inputting space information by dividing complex building structures into minimum unit spaces by applying the concept of spatial division, especially in the design of building structures. It is possible to provide a three-dimensional graphic drawing production system and a method of manufacturing the same using an efficient and economical two-dimensional graphic drawing that can be easily produced and used by designers, builders, and managers.

In order to achieve the above object, a three-dimensional graphic data production system using the two-dimensional graphic drawing of the present invention and a method of manufacturing the same in a computer system that can manipulate a two-dimensional graphic drawing to extract surface shape information, the surface shape Each object is combined with hierarchical spatial information defining the spatial position of the object represented on the two-dimensional graphic drawing including the information, and detailed object position information and object characteristic information according to the hierarchical spatial information. By independently constructing 3D graphic data (logical 3D graphic shapes) that are not bound to specific coordinate values, and then physical 3D graphic data (specifically, generating the logical 3D data based on specific coordinate values) To provide a means for generating a three-dimensional shape drawing). FIG separated three-dimensional graphics data production system and the 3D graphic data, the manufacturing method of the structure, such as using the same using a two-dimensional graphic diagram based on the 5 will be described in detail.

[3D graphic data production system using 2D graphic drawing]

3D graphic data production system using 2D graphic drawing

In a computer system 100 in which an operator can manipulate a two-dimensional graphic drawing for a given construction or manufacturing field using an input device 40 such as a keyboard and a coordinate input device and an output device 50 such as a monitor, Information storage means (10) in which hierarchical spatial information (11), location information (12), and object characteristic information (13) of an object implemented on the two-dimensional graphic drawing are input and stored by an operator's input device operation. ; Logical three-dimensional data generation means for combining the object characteristic information and the positional information with the surface shape information extracted from each object of the two-dimensional graphic drawing to calculate a logical three-dimensional graphic shape that is not affected by a specific absolute coordinate value. 20; And physical three-dimensional data generating means (30) showing the logical three-dimensional data based on a specific coordinate value.

As can be seen in FIG. 2, the system of the present invention displays a two-dimensional graphic drawing on an output device 50 such as a monitor, which is input device such as a keyboard 41 and a position coordinate input device 42 (mouse, etc.). 40) based on the computer system 100 that the operator can arbitrarily manipulate the two-dimensional graphic drawing.

A program for creating the 2D graphic drawing itself may use a commercially available 2D CAD program 21 or the like, and the 2D graphic drawing 22 includes an object to be represented (in the case of an architectural structure, a wall according to the construction type). The planar shape of the back) is shown in planar shape using dots and lines in a planar manner, and the planar shape information extracted using a separate program 1 is included in the two-dimensional graphic drawing.

In other words, if the surface shape information is described as an example of a building structure, the building structure may be divided into upper concepts from lower concepts including tools, copper, floors, households, rooms (meeting rooms, warehouses, etc.), and the lowest level. The conceptual space (which may correspond to the thread or may be a layer in some cases) is the finishing work area (floor, baseboard, wall, ceiling, molding and curtain) as shown in Figure 3a, depending on the type of work to complete the space. Boxes, etc.), skeleton work areas (bases, columns, beams, slabs, retaining walls and stairs) as shown in FIG. , Struts, underground continuous walls, etc., facility work areas (such as ventilation equipment, sewage pipes, storm pipes, gas pipes, etc.) as shown in FIG. 3D, and power process areas such as switchboards, plants, extensions, cables, and outlets as shown in FIG. Communication facility, communication station, communication In detail it can be divided into a table, terminal, communication connectors 0 kinds sites), such as and the like in the present invention is referred to this hierarchical information space (11). The parts according to the various types of work are represented by a certain plane using points and lines on a two-dimensional graphic drawing, and such a plane usually has a certain shape such as a circle or a rectangle. In order to implement these various types of faces as independent elements, the coordinate values of the face, the reference axis of the face, the tilt angle of the face, the radius in the case of a circular face, the relative distance to the reference axis of the face, It is necessary to have basic information for displaying in three dimensions such as thickness, direction of projection of the surface, and distance of projection of the surface, which is generated using separate program 1 and included in the two-dimensional graphic drawing. In the present invention, the object characteristic information 12 is referred to and combined with the hierarchical spatial information 11 through a separate program 1 on the two-dimensional graphic drawing. The shape of the surface of a specific part is extracted from the two-dimensional graphic drawing 22 including the object characteristic information and the hierarchical spatial information through a separate program 1, and the extracted surface is the surface shape information 23a according to the present invention. It is called. This surface shape information is combined with the positional information 23b described later to generate logical three-dimensional data 24.

The information storage means (10) is a hierarchical spatial information (11), location information (12) and the object is connected to the object displayed on the two-dimensional graphic drawing by the operator using the keyboard 41 or the position coordinate input device 42 It is stored by inputting the characteristic information 13, a secondary storage device such as a hard disk or CD can be used and has a separate interface on the system.

The hierarchical spatial information 11 is spatial information on the spatial position of each object (which may be a detailed part of an architectural structure or a detailed part of a mechanical device, etc.) on a two-dimensional graphic drawing. For example, if an object on a two-dimensional graphic drawing is a floor plan of one of the building structures, then that floor is a specific generation, the generation is a specific copper, the copper is a specific tool, It can be divided into specific complexes, and can be divided into specific threads as sub-concepts, and the spatial information such as the layers or threads will have a part corresponding to each process. , Baseboards, walls, ceilings, moldings, curtain boxes, etc. , Earth anchor, strut, underground continuous wall, etc.), facility work area (ventilation device, sewage pipe, storm pipe, gas pipe, etc.), electric process part (power distribution site, switchboard, plant, extension, cable, outlet, etc.) Communication industry such as communication cable, terminal, connector, etc.).

The hierarchical spatial information 11 is input according to the hierarchical space (just, tool, household, building, floor, room, etc.) required by the operator according to the object of the 2D graphic drawing. If the object of the two-dimensional graphic drawing is about the complex, the operator will enter the spatial information of the tool, generation, building, floor and room of the subconcept, depending on the characteristics of the object and the number of spatial information of the subconcept and The range is changed. 4A illustrates an input state of the hierarchical spatial information. In FIG. 4A, hierarchical / equilibrium information can be inputted in a window window by a separate program 1 as hierarchical spatial information in relation to a specific two-dimensional graphic drawing. It is configured to be connected internally to the two-dimensional CAD drawing. Thus, a single hierarchical spatial information can be connected to a number of objects on the two-dimensional CAD drawing.

The location information 13 is information on the location of an object in a two-dimensional graphic drawing to which the above-described hierarchical spatial information is connected. The location information is described as an example of an architectural structure as follows. If the hierarchical spatial information of the object on the 2D CAD drawing is a floor plan of a specific floor, the lower spatial information immediately constituting the floor corresponds to a room such as a warehouse or a library, and the upper upper spatial information corresponds to the same. The two-dimensional CAD drawings related to the upper and lower spatial information may be many drawings. Since the two-dimensional CAD drawings do not have reference points set to each other, they may relatively determine the positions of specific reference points so that they can be connected to each other by specific reference points. There is a necessity, and the information about the reference point is referred to as position information 13 in the present invention, and is input by the operator to the keyboard or the coordinate input device. In fact, in the system of the present invention, the coordinate value will be internally, and the information on the relative position of each object in the two-dimensional CAD drawing is characterized, and will be included in the two-dimensional CAD drawing unlike the hierarchical spatial information described below. Rather, it is stored separately in the system of the present invention so that it can be used as needed.

The object characteristic information 12 is information on a specific part of an object of a two-dimensional graphic drawing to which the above-described hierarchical spatial information is connected. The object characteristic information is described as an example of a building structure as follows. If the two-dimensional graphic drawing is a floor plan of a specific floor of a building structure, the subspace information will be a room such as a library, a warehouse, etc., and if a worker designates a room such as the warehouse (a separate code and The number corresponding to the code is pre-selected by the worker in the work window through a separate program), and in order to construct the warehouse, a finishing work is required to form a specific part constituting the warehouse, and the finishing work requires flooring. There may be information on specific areas such as floorboards, walls, ceilings and moldings. Specifically, the height of the baseboard, material code and price, etc., and the object characteristic information is input by the operator through a separate program 1, which is illustrated in FIG. 4E. The object characteristic information 12 is included in a two-dimensional graphic diagram in the system of the present invention, and the object characteristic information is combined with surface shape information and position information to form logical three-dimensional data described below.

The means 20 for generating the logical three-dimensional data includes a specific program 2 for combining the surface shape information extracted from the two-dimensional CAD drawing including the hierarchical spatial information and the object characteristic information described above and the location information stored in the system. By this combination, the space and location of the object of the 2D graphic drawing can be determined, and the specific surface (plane shape information) that actually composes the object can be determined. Can be. At this time, the reference point that defines the position of the object relatively inside the system is already specified, but the reference point of the actual three-dimensional shape is not defined. The same object is duplicated by not defining the reference point that is actually present. The effect is not to form internally in the system. In other words, when a worker selects a specific layer (for example, one layer) including each thread, all information about each part of the thread is combined to generate a three-dimensional shape internally in the system, and a layer different from the specific layer ( For example, if the second layer) is selected, the same area information used in the first floor is newly combined to fit the second floor again, and since the separate information is not combined, the same area information does not need to be duplicated and stored in the system. It is possible to provide a three-dimensional shape very efficiently.

When the logical three-dimensional data is generated as described above, it is necessary to express the actual three-dimensional shape with respect to a specific position. In order to display the actual three-dimensional shape, the logical three-dimensional data cannot be used as it is, and the operator Needs to be transformed into the actual physical three-dimensional shape according to the desired location. This is because the logical three-dimensional data does not exist as the data that the worker can recognize from the actual position. This is automatically converted in the system of the present invention by a separate program 2, and no separate work is required, and in the present invention, this is called a means 30 for generating a physical three-dimensional graphic. Is implemented. When the operator selects a specific location, for example, a tool, a copper, a floor, etc. in a separate input window using an input device such as a keyboard or a mouse, such as contained in hierarchical spatial information, the operator selects a desired location through an output device. Three-dimensional shape, that is, physical three-dimensional data is derived. As a result, the operator can easily check the three-dimensional shape for a specific position desired, and by adding a variety of other information to the three-dimensional shape is provided a base that can be used according to the desired purpose. 4G shows an example in which such a physical three-dimensional shape is derived.

[3D Data Production Method Using 2D Graphic Drawing]

3D data production method using a 2D graphic drawing,

On computer system 100, which allows an operator to manipulate two-dimensional graphical drawings of a given building or manufacturing sector using input devices such as keyboards and coordinate input devices,

(S10) inputting and storing hierarchical spatial information of an object implemented on the two-dimensional graphic drawing in a system by a separate program;

(S20), in which position information is input and stored in a system by using a separate program for an object implemented in the 2D graphic drawing;

An object on the two-dimensional graphic drawing is designated using a separate program, and object characteristic information is input and stored on the system to the designated object (s30);

Combining hierarchical spatial information and object characteristic information with an object on the 2D graphic drawing by using a separate program (s40);

After the surface shape information of the object on the two-dimensional graphic drawing including the hierarchical spatial information and the object characteristic information is generated by a separate program, generating logical three-dimensional data by including the position information (s50). ;

Outputting the logical three-dimensional data as physical three-dimensional data to an output device using a separate program (s60);

It includes, and a method of forming a three-dimensional shape using a two-dimensional graphic drawing for the building structure will be described with reference to FIG. 4 as a specific example.

Steps s10 to s60 are based on a system in which the operator can edit the two-dimensional graphic drawing while the two-dimensional graphic drawing is already completed, and based on the state in which the two-dimensional graphic drawing is displayed on an output device such as a monitor on the system. (Of course, the operator can work even when the 2D graphic drawing is not displayed on the monitor. This means that inputting hierarchical spatial information, location information, and object characteristic information is performed by the program. Because you can work separately from the drawing.)

[S10 step]

In the step s10, the operator sees the objects (such as a floor plan of a specific floor of an apartment building, etc.) represented in a two-dimensional graphic drawing on the system, and these objects belong to which floor / floor, and in which compartment (specific agreement). It is a step of registering using the input window provided by the separate program 1 as shown in FIG. 4A to determine whether the floors may be made of several drawings. Will enter. Of course, the hierarchical spatial information may have a tool at a higher level above the same layer, which is not shown in FIG. 4A, but using a separate input window, information about each tool (such as a tool code and a tool name) may be used. In addition, it can also be composed of households (households) and rooms (rooms) at the lower level below the same level, so if necessary, the code and name for each household and room can be registered. Registration per square meter). As described above, the hierarchical spatial information is input by the worker from the highest level to the lower level according to the object, and its details may be changed according to the purpose of the work and the detailed work.

At this time, the operator can specify the specific motion layer as a certain compartment, and this compartment specific operation is indicated at the right end of Figs. 4A and 4B. 4A and 4B, each of the same layer is designated as A section, and its detailed name is AAAAAAA in FIGS. 4A and 4B. In the divided state, as shown in Fig. 4c, A0011 and the like to provide a criterion that can be divided into the lower level of the room for each floor.

When the hierarchical spatial information is input and registered, it is stored by a separate storage device on the system 100, and this information is connected to each object included in the 2D graphic drawing by a separate program 1, and such a connection work. By providing a foundation for the logical two-dimensional data is configured.

This hierarchical spatial information must be selected and registered by an operator to correspond to all two-dimensional graphic drawings. This is because a final three-dimensional graphic drawing may not be generated even if one two-dimensional graphic drawing is missing. This requires modification / additional work steps.

[S20 step]

Step s20 corresponds to forming a vertical positional relationship such as classifying the space in which the building structure is composed in step s10, and inputting and storing information about the space, thereby determining the horizontal positional relationship of the building structure. Entering and saving information. In other words, it provides information about the horizontal positional relationship of tools, copper, floor, household, and room of the building structure, which is also stored separately in the system, and setting the reference point for each tool, copper, floor, household, and room. When the drawings of each tool and the like are made up of several drawings, the reference points are input so that the relationships between the drawings and the drawings between the upper and lower levels can be connected to each other. This allows many two-dimensional graphic drawings that represent a building structure to be connected by establishing vertical (hierarchical spatial information) and horizontal (location information) positions so that, even if one drawing is selected by the operator, its position with other related drawings can be determined. It naturally forms in the phase.

Specifically, it is as follows.

When the operator registers the reference point of the tool of the building structure using the input window provided as a separate program 1 and saves it on the system, it calculates the position of the tool, the position of motion, the position of the floor, the position of the household and the position of the room. Used to

When the worker registers the motion reference point of the building structure using the input window provided as a separate program 1 and stores it on the system, it indicates the location of each motion, the location of the floor included in the same building, the location of the household and the location of the room. Used to calculate

When a worker registers the reference point of the floor of a building structure using the input window provided as a separate program 1 and stores it on the system, it is used to calculate the location of each floor, the location of the household belonging to the floor, and the location of the room. ,

When the worker registers the reference point of the generation of the building structure using an input window provided as a separate program and stores it on the system, it is used to calculate the location of each household and the location of the room. Of course, the range of the horizontal position level according to the property of the object in the two-dimensional graphic drawing can be adjusted flexibly.

[S30 step]

In detail, the step s30 includes a step (s31) in which an object on a two-dimensional CAD drawing is designated using a separate program, and a step (s32) in which object characteristic information is input and stored in the system on the designated object.

In step s31, the operator selects a two-dimensional graphic drawing about a plane on a specific floor on a certain hierarchical space level, that is, designates an object according to a work object, such as specifying a room constituting each floor. In FIG. 4C, a specific floor of a building structure is displayed on a monitor on a system, and each room (storage, library, conference 1 and 2, office, locker, shower room, etc.) constituting a specific floor is divided.

(This division is already made on a two-dimensional graphic drawing, and this configuration is made by a separate program. That is, the operator divides each room's boundary into a boundary line of each room on the two-dimensional graphic drawing. This division work can be modified by the operator, and the modified boundary for dividing each room is stored in the two-dimensional CAD drawing representing each room, thereby deriving the detail of each room. A borderline is created for this purpose and this is illustrated in FIG. 4D.)

Register the name of each room (storage, library, conference 1 and 2, office, locker, shower room) and room number (a0001, a0002, etc.) using the input window provided by the separate program as shown in Figure 4e. Since the hierarchical spatial information and the location information are already registered in the previous steps (s10 and s20), such information can also be confirmed in FIG. 4E. Of course, the contents can be changed according to the object selected by the worker. If the worker selects a two-dimensional CAD drawing for a civil engineering work, a two-dimensional CAD drawing for a soil block, etc. among the civil engineering work for a particular building will be displayed, and the operator designates a desired object and then signs the designated object. Naturally, it can be registered by using an input window provided by a separate program.

Step s32 registers the characteristic information, i.e., object characteristic information, for the parts such as floor, baseboard, wall, ceiling, molding and curtain box, while specifying specific parts according to the type of work (for example, finishing type) for each designated room. It's a step.

The object characteristic information is input by the operator by an input window provided by a separate program, which is illustrated in FIG. 4F. In FIG. 4F, a locker room of one building and two ground floors of a building structure is designated, and details of the locker room, that is, floor, baseboard, wall, ceiling, molding, and curtain box, can be selected. You can enter floor vertical position, baseboard height, wall vertical position, molding vertical position, molding width, molding thickness, curtain box vertical position, curtain box width and curtain box depth. Of course, if each sub-part consists of separate sub-parts, you can enter them separately, and if you need additional information about each sub-part, you can also enter it separately.

[s40 steps]

In step S40, hierarchical spatial information and object characteristic information are combined with an object on a 2D graphic drawing by using a separate program. In other words, when a worker selects a certain object (a specific building, a specific floor, or a specific part of a specific room) as a two-dimensional graphic drawing on the system, the hierarchical spatial information, location information, and object characteristic information are already registered and stored as described above. Since it is a step, all objects and the information need to be connected to each other so that they can be used in connection with each other. Of course, this work is not done by the operator, but by a separate program 1 on the system.

In this way, the objects on all two-dimensional graphic drawings of the building structure that can be identified by the worker on the system are linked to all the information registered by the worker, so that any information on the object is selected regardless of which two-dimensional graphic drawing the worker selects. Will be included. Specifically, when a worker selects and executes a code of a specific room of a building structure on the system, the object property information of the room corresponding to the room code on the corresponding two-dimensional graphic drawing is connected. Thus, the present invention will be described later. The basis for generating the logical three-dimensional data of.

[s50 steps]

In the step s50, the plane shape information of the object on the two-dimensional graphic drawing including the hierarchical spatial information and the object characteristic information is generated by a separate program 1 (s51 (23 of FIG. 2)) and the position information is included. And a logical three-dimensional data is generated (S52, 24 of FIG. 2), and the two-dimensional drawing is performed in a state in which the objects on the two-dimensional graphic drawing and various information input by the operator are connected in the steps before the s50 step. This is the step of shaping in three dimensions.

In order to convert an object on a two-dimensional graphic drawing into a three-dimensional shape, the relative horizontal and vertical positions of the object must be set at a specific reference point, and thickness information for displaying the thickness of the object must be set in advance. These settings are pre-registered in the previous step of step s50 described above and stored on the system, and can be combined with a two-dimensional site selected by an operator to be changed into a three-dimensional shape.

Specifically, the shape of each part constituting a specific thread of a specific layer is composed of a floor, a baseboard, a wall, a ceiling and a curtain box in the case of the finishing work. Since each part will be composed of a certain surface, the position of the shape relative to the surface of each part is determined relative to the code position of the specific chamber (by position information), and the shape of the surface is determined by the object characteristic information. Will be decided. In the present invention, the result of the position and shape of the surface is called surface shape information 23a.

When the surface shape information is described as an example of the floor of the finishing work site, the floor is formed by using the coordinate values of the partition lines of the room specified in step s31 described above to form the shape of the floor, using the vertical position value of the floor The height of the floor is determined and the surface shape information of the floor is generated.

In the case of the baseboard, each coordinate of the partition line of the thread is used as the bottom coordinate of the vertical plane of the baseboard, and the top coordinate of the vertical plane is determined by the height of the baseboard. (For example, the coordinate value of a specific room is P1, P2, P3, P4. If the height of the dustpan is H in the configured state, the coordinates of the dustpan vertical plane are (P1, P2, P1 + H, P2 + H), (P2, P3, P2 + H, P3 + H), (P3, P4, P3 + H, P4 + H), (P4, P1, P4 + H, P1 + H)) The PA, P2, P3, P4 will be the X, Y axis value in the coordinate axis, H value Naturally, the Z-axis value is set, which generates the surface profile information of the baseboard.

In case of wall, if the coordinate value of the partition line of the room is used as the lower coordinate of the wall surface, and the ceiling height which becomes the upper part of the wall is the height of the wall surface is created by adding the upper coordinate value of the wall surface to the lower coordinate, and the vertical position of the wall is inputted. In the coordinates constituting the wall, the Z-axis value is added to the wall vertical position to generate the shape coordinates of the wall. Finally, the wall shape information of the wall is generated.

For the ceiling, coordinate values of the ceiling surface shape are generated using the coordinates of the partition line of the yarn, and surface shape information about the ceiling is generated.

In the molding, the surface shape information of the molding is generated by using the vertical position and width of the molding in the coordinate values of the partition line of the yarn.

When curtain box presence / absence is specified in the window code, the curtain box surface shape information is generated by using the coordinates of the window code, the dimensions of the window, the vertical position and the width of the curtain box.

Each surface shape information described above is generated by a separate program on the system and stored separately. At this time, all the surface shape information need not be stored in advance. Since the architectural structure is composed of numerous objects, and pre-storing the planar shape information about these objects will slow down the system's work speed, so the planar shape of the object selected by the worker and the objects related to the object is selected. Preferably, the information is stored.

Such surface shape information includes hierarchical spatial information, location information, and object characteristic information (23b, which is distinguished from storage registered), which is referred to as logical three-dimensional data in the present invention. This is distinguished from physical three-dimensional data which will be described later. The difference is that each object by the logical three-dimensional data is composed of a plurality of reference coordinates without all coordinate values having absolute reference coordinates. That is, the logical three-dimensional data has the advantage that it can be displayed in various ways depending on the operator's choice in a state that is not determined by the absolute reference value. The step of generating such logical three-dimensional data is the step s52.

It is sometimes difficult to three-dimensionalize all of the two-dimensional data that is the basis of logical three-dimensional data to its original shape. In this case, the worker can add or modify the partial shape of the object. Hierarchical spatial information, location information, and object characteristic information about an object to be modified or added are inputted by a worker using a separate program to be registered / stored. This step may occur as needed, so it will be an additional / secondary step, which is referred to as s53 in the present invention.

[S60 step]

The step s60 is a step of generating the overall shape of the building structure by changing the logical three-dimensional data to three-dimensional data based on the absolute reference coordinate value. 4G shows a two-dimensional CAD drawing of a specific copper / floor of a building structure such as an apartment.

Unlike the logical three-dimensional data generated in step s52, the physical three-dimensional data has all the coordinate values constituting the graphic relative to one absolute coordinate, so that the operator can create a two-dimensional CAD drawing in an output device such as a monitor. You can check the dimensioned shape.

A concrete transformation step will be described taking the case of a building structure. The vertical position of each floor is calculated from hierarchical spatial information and location information, the floor reference point is calculated, and the horizontal position of each floor is calculated. Reposition the shape of the surface of the specific part of the object according to each type at the location using the face shape information, generate the face shape coordinate value of the relocated object using the object characteristic information as the relative coordinate value with respect to the layer reference point, The physical coordinates based on the absolute reference point are finally obtained by applying the repositioned face coordinates of the geospatial information to the layer reference point, and obtaining the tool reference point of the hierarchical spatial information, and applying the plane coordinates applied to the layer reference point. It is a process of obtaining a value.

According to the present invention, a logical three-dimensional shape is manufactured by adding information required for a three-dimensional shape by using a two-dimensional drawing manufactured by a two-dimensional design method that has been used traditionally. Existing two-dimensional drawings produced by the dimensional design method can be used as it is, so there is no need to change the existing design method and concept, and the complex structure is divided into the minimum unit space by applying the space division concept that is easy for the designer to access. This allows a logical and phased approach and makes it easy for designers to understand.
