Description

  The present invention relates to a CAD information generation apparatus, a CAD information generation method, a CAD information generation program, a medium, and a three-dimensional model, and in particular, a CAD information generation apparatus and a CAD information generation method for generating three-dimensional CAD data according to process management data , A CAD information generation program, a medium, and a three-dimensional model.

  Conventionally, in product development and structure design, several prototypes are created at the design and development stages, and the appearance and performance are evaluated. The most primitive prototype model includes a clay model made of clay and a wood model made by cutting wood. However, such model production has problems such as manpower, time and cost, poor reproducibility, and too much dependence on the skill of the model craftsman. Now that computer technology has advanced in place of the conventional prototype model production technology, the rapid development of the prototype product is created using 3D CAD data for the developed product, and a prototype model is created using this 3D CAD data. A technology called “typing” has been developed and put into practical use. This is a technique for creating a target “stereoscopic model” from three-dimensional CAD data at extremely high speed and low cost without manpower and time.

  A typical technique for rapid prototyping is the “layer fabrication method”, which is based on the three-dimensional CAD data of an object and slice data (to be precise, a thin plate having a slight thickness constituting the object). The three-dimensional object (three-dimensional model) is formed by stacking the sliced data one layer at a time. And what is put to practical use in the layered modeling method is broadly divided into “photocontrast method” in which a photocurable resin is solidified with a laser, and a solidifying agent / binder supplied by an ink jet method or the like. There is a “powder-fixing-type lamination method” in which the shape is solidified, but the latter is superior in terms of low cost, high speed, and colorization. Regarding the “powder fixing type laminating method”, several related patents have been filed and acquired, and three-dimensional printers using the same have been put on the market. For example, as a conventional technique, there is a “method and apparatus for manufacturing a model of a three-dimensional object” (see Patent Document 1).

JP-T-2004-538191

  Conventionally, the focus has been on modeling a target three-dimensional object more accurately, cheaply, and in a shorter time from already created three-dimensional data. This means that if the product being developed is a single product such as a machine part or a mobile phone terminal, that is, a model of a relatively small article, there is not much problem with setting such a development target. “Optical imaging” is suitable for various applications.

  On the other hand, in recent years, the “powder fixing type laminating method” has been technically innovative, and it has become possible to form a “colored three-dimensional object” at an extremely low cost and at high speed. For this reason, application to various fields other than shaped articles such as machine parts is being expected.

  However, in the case of a three-dimensional model of a building or a civil engineering structure, if a three-dimensional model is created using the three-dimensional CAD data of the building or the civil engineering structure as it is, the user can observe the “completed monolith” Will be created as "Only the appearance of the completed three-dimensional model". In the case of buildings, civil engineering, and construction structures, it is important to observe the final structure as a whole, but grasp the status of the structure at each stage until the structure is completed. It is very important to do.

  In particular, in large-scale structure construction projects, intermediate inspections are set at each stage of the process, and visual progress confirmation is set monthly or weekly. It is thought that it is very effective to grasp the appearance of the structure. However, in the prior art, there is final three-dimensional CAD data of the structure, but it is difficult to extract the three-dimensional CAD data of the intermediate structure from the intermediate structure. The appearance is grasped on a paper base such as drawings at the construction stage. In addition, in the case of buildings, civil engineering, and construction structures, it is important to have an intermediate structure or an external structure that can be observed from the outside, but room allocation, internal structure, cross-sectional structure, layer structure, concrete arrangement The situation is often more important. However, in the prior art, if the three-dimensional data of the three-dimensional object is used as it is, the inside of the intermediate stage building or structure cannot be seen. That is, it is not possible to create a three-dimensional model capable of observing the structure of the structure under construction, the room layout of the structure, the internal structure, the cross-sectional structure, and the concrete bar arrangement.

  In order to create a solid model of a structure at an intermediate stage, construction is performed by instructing a skilled operator of 3D CAD software that requires complicated operations to process the original 3D CAD data. It is necessary to create CAD data for an “incomplete solid model” at an intermediate stage so that a building on the way can be observed. Or, instruct a skilled operator of 3D CAD software who needs complicated operations to process the original 3D CAD data so that the room layout, internal structure, cross-sectional structure, and concrete bar arrangement can be observed. Thus, it is necessary to create CAD data for a “notched solid model” in which a part of the building is cut out so that the cross section of the building can be observed. As described above, even if CAD data for a “notched three-dimensional model” is created by bothering the hands of a CAD operator having specialized skills, and the internal structure can be observed, In the “model”, there is a dilemma that the “whole” structure and appearance of buildings and civil engineering works (civil engineering structures) cannot be observed.

  Also, civil engineering structures such as dams, bridges, roads, and buildings, buildings, etc., or golf courses, parks, towns, and other landforms, civil engineering structures, buildings, etc. that are developed by such projects, It is often managed by a “plan management system”. In the construction plan management system, progress plans at each stage (process) of construction are managed in chronological order, and the actual construction progress is managed by volume and plan volume on a monthly, weekly, and daily basis. It is possible to compare and confirm whether it is proceeding as planned. In public construction, the deadline management until the completion of the structure is strict, and if construction is not completed by each inspection date or scheduled completion date due to construction delay, etc., the country or local government that is the owner of the huge penalty or compensation There is a risk that you will need to pay.

  Therefore, as described above, the construction plan management system is used to manage the construction progress on a monthly and inspection day basis. For example, from the information such as “completion of earthwork 500 cubic meters” as the volume information, There is a problem that it cannot be easily grasped unless it is an expert how and in which part of the structure (delivery product) that is the construction target is progressing. Therefore, veteran construction managers manage the overall construction progress by examining the volume information and related information of the construction plan management system and comparing the volume information with the actual structure. However, there is no technique for grasping the volume information and plan information with a CAD drawing or a three-dimensional model.

  Moreover, if the development project becomes large-scale, it is difficult for even an expert to accurately grasp the construction progress. It is difficult for even civil engineering and construction specialists to accurately grasp the progress of construction, which means that non-expert owners and related parties can hardly grasp the delay in construction progress. It will be. This is a big problem in terms of compliance, because in the event of fraud or any mistake, only an expert can recognize it.

  Under such circumstances, if the construction plan management system and CAD system (and model) can be linked and linked, the progress of the construction can be visualized (visualization, visualization). Not developed. If the construction progress can be visualized, not only specialists but also owners and related parties will be able to grasp construction progress accurately and in a timely manner.

  Therefore, an object of the present invention is to obtain a CAD information generation device, a CAD information generation method, a CAD information generation program, a medium, and a three-dimensional model, particularly, three-dimensional CAD data of a structure at a stage corresponding to the output of the structure process. Is to generate. Another object of the present invention is to provide a CAD information generating apparatus and CAD information generating apparatus for generating three-dimensional CAD data so as to make a target three-dimensional object as if it were made as a single object, but making the single object separable.

<Embodiment 1>
FIG. 1 is a block diagram showing an outline of a CAD information generating apparatus according to Embodiment 1 of the present invention. As shown in the figure, the CAD information generating apparatus 100 (CDG) includes a control unit (processor such as a CPU) 110, an input unit 120, an output unit 130, a communication unit 140, a storage unit 150, and a display unit 160. And have. The storage unit 150 stores process management data PMD and CAD information CDI. The control unit 110 includes an acquisition unit 111, a process management unit 112, a CAD information generation unit 113, and a three-dimensional output control unit 114.

  The process management data PMD stored in the storage unit 150 includes structures (artificial structures, buildings, roads, dams, ponds, golf courses, golf courses, harbors, dikes, or soils). Each of a plurality of work steps for constructing a layer of natural objects such as gravel, stone, hills, small mountains, cliffs, etc., or some combination thereof) The process identifier associated with is included. Similarly, the CAD information CDI stored in the storage unit 150 includes a plurality of three-dimensional objects that are constituent elements included in the structure and object identifiers associated with each of the three-dimensional objects. The object identifier corresponding to the process identifier associated with the work process is included. It is preferable to use the process management data PMD stored in the storage unit of the present apparatus (CDG100). However, whenever data is required for processing, the process management data PMD is sent from the process management server PMS to the network. You may acquire via NET. Alternatively, this apparatus may be built in the process management server PMS or the CAD system CD1.

  The acquisition unit 111 is information on the amount of work of at least one work process for constructing a structure (the volume of the work process performed, the planned volume of the work process on the execution plan, specifically, 6000 cubic meters of earth filling, slope work 40,000 square meters). The acquisition unit 111 can also function as a CAD information acquisition unit. When the acquisition unit 111 functions as a CAD information acquisition unit, it is at least an artificial structure (a building, a building, a dam, a bridge, a road, etc., and preferably these structures and the land on which they are constructed). 3D CAD data of a three-dimensional object including terrain, etc., and including three-dimensional objects for a plurality of components constituting the structure (three-dimensional object), After performing such association, the information is stored in the storage unit as CAD information CDI. The acquired three-dimensional CAD data of the structure is created by the CAD system CD1, is received by the communication unit 140 via the network NET, and is stored in the storage unit 150. The acquired three-dimensional CAD data is modeled as a three-dimensional model in a three-dimensional space by the three-dimensional output control unit 114, and this three-dimensional model (structure; solid object) is projected onto a two-dimensional plane (projection plane). Then, the display unit 160 displays the projected “structure” (three-dimensional object). The acquisition unit 111 may acquire work amount information of a work process alone, but cooperates with an operation reception unit (input unit) that receives an operation by a user, a communication unit 140 that acquires information from the outside, or the like. To obtain information.

  The process management unit 112 associates the work amount information acquired by the acquisition unit 111 with the corresponding work process among the work processes included in the process management data, identifies the work process associated with the work amount information, and The process identifier of the identified work process is extracted. As the process identifier, a word indicating a process, a number, an alphabet, or a combination of these is used, but an integrated step code and a unit price code set and used by an integrating system are convenient. In addition, it is necessary to associate the process identifier with the object identifier. However, if an integrated step code and unit price code are used as the same identifier, a correlation table or the like is unnecessary, and preferably, the process identifier and the object identifier are used. And common code.

  Based on the process identifier extracted by the process management unit 112, the CAD information generation unit 113 specifies a three-dimensional object including an object identifier corresponding to the process identifier from a plurality of three-dimensional objects included in the CAD information. The CAD information corresponding to the process management including the three-dimensional object is generated. The three-dimensional output control unit 114 models a structure using CAD information corresponding to process management as a three-dimensional model in a three-dimensional space, and the three-dimensional model (structure; three-dimensional object) is converted into a two-dimensional plane (projection). The display unit 160 displays the projected “structure” (three-dimensional object). For example, when information up to A, B, and C is acquired as work amount information among five stages of work processes of A, B, C, D, and E, a three-dimensional object corresponding to the work processes A, B, and C The structure in the middle of construction consisting of is displayed on the display unit. That is, a structure based on 3D CAD information that accurately and timely reflects process management data can be observed on a screen or with a three-dimensional model by a 3D printer, and process management can be visualized.

  The acquired information and data, the extracted process identifier, the generated three-dimensional CAD object, and the three-dimensional CAD data including it are preferably stored in the storage unit 150 as intermediate data. The three-dimensional output control unit 114 is a device driver of the three-dimensional printer PRN1 or a functional unit having a function thereof, and a target three-dimensional object is three-dimensionally output via the output unit 130 using the generated three-dimensional CAD data. It is output (three-dimensional printing) to the CAD printer PRN1. The generated three-dimensional CAD data may be transmitted / output to the terminal PC1 which is an external device via the three-dimensional output control unit 114 or the communication unit 140, and stored on these terminals. In this way, the generated information and intermediate data and acquired data are transmitted to the outside, displayed on the display unit, and the generated information and intermediate data and acquired data are stored in the storage unit. It should be noted that other embodiments described below are possible as well. The CAD information generating apparatus 100 is a computer such as a general-purpose computer, a special purpose computer, a server, a PC, or a tablet terminal, or a functional unit and a processing procedure (method) of the apparatus are realized (executed) on the computer. It is preferable to construct a CAD information generation device on the computer by holding the program module to be stored in a processor, CPU (processor or its cache) or storage unit of the computer, or by reading it from an external server or storage. The same applies to each of the following embodiments.

  FIG. 2 is a flowchart illustrating an example of processing executed by the CAD information generation apparatus according to the first embodiment. As shown in the figure, in step S11, the storage unit 150 stores a plurality of work processes for constructing a structure, process management data including a process identifier associated with each of the work processes, and the structure. A CAD that includes a plurality of three-dimensional objects that are constituent elements and an object identifier associated with each of the three-dimensional objects, the object identifier corresponding to the process identifier associated with the work process of the three-dimensional object Store information. Next, in step S <b> 12, the acquisition unit 111 acquires work amount information of at least one work process for constructing a structure that is a process management target. In step S13, the process management unit 112 associates the acquired work amount information with the corresponding work process in the work processes included in the process management data, and identifies the work process associated with the work amount information. Then, the process identifier of the specified work process is extracted. The storage operation in step S11 is performed only once at the beginning, and steps S12 and S13 are repeatedly performed. For example, it is preferable to acquire, associate, and extract every day or week.

  Next, in step S14, the CAD information generation unit 113 identifies a three-dimensional object including an object identifier corresponding to the process identifier from a plurality of three-dimensional objects included in the CAD information based on the extracted process identifier. Then, CAD information corresponding to process management including the identified three-dimensional object is generated. Finally, in step S15, the three-dimensional output control unit 114 (CAD software module or the like) draws a structure defined by the process management-compatible CAD information on the display unit 160. Or you may output to the three-dimensional printer PRN1, and may form the solid model which shows the output of the said process, and a work stage. The three-dimensional output control unit may output the generated three-dimensional data to another external three-dimensional printer or CAD system. The generated three-dimensional data may be displayed on the display unit using the data or stored in the storage unit 150 in order to confirm the status of the construction stage. As described above, the storing step does not have to be executed every time, and only needs to be executed once unless the target data or information is changed.

  FIG. 3 is a schematic diagram showing the process management data of the embankment type road construction stored in the storage unit. As shown in the figure, the process management data PMD1 has time on the horizontal axis and the order of the processes on the vertical axis. When displayed, the process management data PMD1 is preferably in a gun chart format as shown in the figure. . In the present embodiment, the embankment type road construction is composed of four work processes. The first work process is the fill work P1, the second work process is the slope shaping (correction) work P2, the third work process is the roadwork work P3, and the fourth work process is the road work. P4. Thus, the order of each work process is defined. Each work process has a process identifier associated with it. It is preferable to use an alphanumeric identifier called a step code, unit price code, integration code, etc. used in the estimation system or integration system. It is. In this example, a process identifier M600 is associated with the embankment work P1, a process identifier N500 is associated with the slope shaping work P2, a process identifier R780 is associated with the road work P3, and a process identifier R900 is associated with the road work P4.

  When the work amount information for each work process, for example, “filling work, 300 m2” is acquired, the apparatus stores the work amount information PQ1 in the storage unit in association with the fill work P1 that is the corresponding work process. Manage. The work volume management function such as the actual work volume and the planned work volume is similar to that implemented in a construction plan management system.

  In the lower part of FIG. 3, CAD information CDI10, that is, structure OB10 defined by the CAD information is presented. A plurality of three-dimensional objects that are constituent elements included in the structure OB10 are displayed as a ground EL10, a fill EL11, a slope-reinforced concrete EL12, a road body EL13, and a road EL14. Although an object identifier is associated with each of these objects, it is preferable to include the object identifier in a reserved field of the object. In this example, an object identifier M600 is associated with the embankment EL11, an object identifier N500 is associated with the slope-reinforced concrete EL12, an object identifier R780 is associated with the road body EL13, and an object identifier R900 is associated with the road EL14. Since the ground EL10 exists at any stage of the work process, the same object identifier as that of the embankment that is the first process is associated with the ground EL10, or is always included when generating CAD information. It is convenient to keep it. As described above, if the process management data and the CAD information are associated with each other and associated with each other, the work amount information as the volume information can be obtained sequentially, and the object that accurately defines the state of the completed work process. It is possible to display a three-dimensional structure that accurately defines the work process status or to form a three-dimensional model.

  FIG. 4 is a schematic diagram for explaining a mechanism for generating three-dimensional CAD data by the processing of FIG. 2 using various data of FIG. In the present embodiment, a case where the acquisition unit acquires the volume information of “filling work” as work information will be described. As shown in the figure, after the volume information for the banking work P1 is acquired, the process management unit uses the acquired work amount information as the banking corresponding to the work process among the work processes included in the process management data PMD11. The work amount information PQ1 is stored in association with the work P1, the work process associated with the work amount information is specified, and the process identifier M600 of the specified work process is extracted. Next, the CAD information generation unit is a three-dimensional object including an object identifier M600 corresponding to the process identifier from a plurality of three-dimensional objects included in the CAD information CDI10 (OB10) based on the extracted process identifier M600. The embankment EL11 is specified, and the process management corresponding CAD information CDI11 (structure OB11) including the specified three-dimensional object and the ground EL10 which is an object that remains unchanged throughout all the works is generated.

  The embedding EL11 may be included as it is. However, in reality, the upper portion of the embedding EL11 is formed with a concave portion by the roller compression in the subsequent process. At this stage, the upper portion of the object is flat, and the actual construction is performed. There is a slight discrepancy with the situation. In order to cope with the case where the object changes between the final stage and the intermediate stage, the intermediate stage fill EL11-1, which is a three-dimensional object at the intermediate stage, is stored in the storage unit. It is more desirable to generate CAD information including the embankment EL11-1 (which is assigned the same identifier) because the structure in the middle of the construction is accurately reproduced. A replacement rule that generates CAD information that is replaced (returned) to the original embedding EL11 is stored in the storage unit when the volume information (in this example, road construction) of the subsequent process of the embedding is acquired. It is preferable to use the rules as appropriate. In this way, the CAD information generation unit forms the three-dimensional object model of the intermediate stage that forms the three-dimensional object at the end of the process based on the acquired work amount information on the three-dimensional CAD data including the extracted three-dimensional object group. As three-dimensional CAD data for What is drawn with the generated three-dimensional CAD data is a three-dimensional object OB11 in the middle of construction. If the generated three-dimensional CAD data is printed and modeled by a three-dimensional printer, it is possible to create a three-dimensional model at the end of a certain stage of such a work process.

  FIG. 5 is a schematic diagram for explaining a mechanism for generating three-dimensional CAD data by the processing of FIG. 2 using the various data of FIG. In the present embodiment, a case will be described where the acquisition unit acquires volume information of “filling work” and “slope shaping work” as work information. As shown in the figure, after the volume information for the banking work P1 and the slope shaping work P2 is acquired, the process management unit uses the acquired work amount information in the work process included in the process management data PMD12. The work process is associated with the embankment work P1 and the slope shaping work P2 and stored as work amount information PQ1 and PQ2, respectively. The work process associated with the work amount information is identified, and the process identifier of the identified work process M600 and N500 are extracted. Next, the CAD information generation unit includes object identifiers M600 and N500 corresponding to the process identifier from a plurality of three-dimensional objects included in the CAD information CDI10 (OB10) based on the extracted process identifiers M600 and N500. Dimensional object embankment EL11 (actually replaced by embankment EL11-1) and slope reinforced concrete EL12 are identified, and the identified three-dimensional object is an object that remains unchanged throughout all construction. The process management corresponding CAD information CDI12 (structure OB12) including the ground EL10 is generated.

  In this way, the CAD information generation unit forms the three-dimensional object model of the intermediate stage that forms the three-dimensional object at the end of the process based on the acquired work amount information on the three-dimensional CAD data including the extracted three-dimensional object group. As three-dimensional CAD data for What is drawn with the generated three-dimensional CAD data is a three-dimensional object OB12 in the middle of construction. If the generated three-dimensional CAD data is printed and modeled by a three-dimensional printer, it is possible to create a three-dimensional model at the end of a certain stage of such a work process.

  FIG. 6 is a schematic diagram for explaining a mechanism for generating three-dimensional CAD data by the processing of FIG. 2 using the various data of FIG. In the present embodiment, a case will be described in which the acquisition unit acquires volume information of “filling work”, “slope shaping work”, and “road construction” as work information. As shown in the figure, after the volume information for the fill work P1, the slope shaping work P2, and the roadwork work P3 is acquired, the process management unit includes the acquired work amount information in the process management data PMD13. The work processes associated with the work amount information are stored as work amount information PQ1, PQ2, and PQ3 in association with the embedding work P1, the slope shaping work P2, and the roadwork work P3, which are the corresponding work steps, respectively. The process identifiers M600, N500, and R780 of the specified work process are extracted. At this stage, since there is no content of the work work information PQ4 for the road construction P4, information including the corresponding object is not generated. Next, based on the extracted process identifiers M600, N500, and R780, the CAD information generation unit, from a plurality of three-dimensional objects included in the CAD information CDI10 (OB10), object identifiers M600, N500, The embankment EL11 which is a three-dimensional object including R780 (here, the embedding EL11-1 is not used but the object included in the final structure is used), the slope reinforced concrete EL12, and the road body EL13 are identified, and the identified three The process management corresponding CAD information CDI13 (structure OB13) including the three-dimensional object and the ground EL10, which is an object that remains unchanged throughout the construction, is generated.

  In this way, the CAD information generation unit forms the three-dimensional object model of the intermediate stage that forms the three-dimensional object at the end of the process based on the acquired work amount information on the three-dimensional CAD data including the extracted three-dimensional object group. As three-dimensional CAD data for What is drawn with the generated three-dimensional CAD data is a three-dimensional object OB13 in the middle of construction. If the generated three-dimensional CAD data is printed and modeled by a three-dimensional printer, it is possible to create a three-dimensional model at the end of a certain stage of such a work process.

  In the above example, the actual volume information is used as the work amount information, but the volume plan information or information including a combination of the volume information and the volume plan information may be used. For example, when the volume plan information is used, for example, CAD information reflecting the assumed volume is generated by a date or the like, and the progress plan can be managed and verified on the screen or as a three-dimensional model.

  FIG. 7 is a schematic diagram showing process management data for road-type road construction stored in the storage unit and a reference table for associating process management data with CAD objects. In this example, as shown in the figure, the process management data PMD1 is the same as that shown in FIG. In this example, the CAD information CDI15, that is, the embedding EL11 that is a three-dimensional object of the component included in the structure OB15 defined by the CAD information, the object identifier KK600, the slope reinforced concrete EL12 the object identifier KK500, the road An object identifier KK780 is associated with the body EL13, and an object identifier KK900 is associated with the road EL14. That is, in this embodiment, since the process identifier in the process management data and the object identifier on the CAD side are not the same, the corresponding object is extracted from the process identifier using the reference table REF1 that associates the two. . The reference table REF1 includes a target element R1 in which a filling process identifier M600, an object identifier KK600 of the filling EL11 are associated, a slope shaping work identifier N5000, and an object identifier KK500 of the slope reinforcing concrete EL12. The target element R3, the road construction process identifier R900, and the object identifier KK900 of the road EL14, which are associated with the associated target element R2, the road construction process identifier R780, and the object identifier KK780 of the road body EL13, are associated with each other. The associated target element R4 is included. This apparatus can use such a reference table when the identifiers do not match on both sides.

  As shown in FIG. 3-7, as the work amount information, the work amount of the work is input and acquired for a certain period such as every day or every week. In such a case, for example, even if CAD information indicating the work status is generated at an intermediate stage where all the filling work is not completed, CAD information including the filling EL11 at all work end stages is generated. A technique for accurately reflecting the work situation in such a situation will be described next.

  FIG. 8 is a flowchart illustrating generation of an object according to a work ratio as an example of processing executed by the CAD information generation apparatus according to the first embodiment. In step S21, the entire work amount information corresponding to the entire work amount of the work process (for example, the earth work 3000 cubic m, the slope work of 40000 square meters, which is the work physical amount of the entire work process) is associated with the work process. . Next, in step S22, the process management unit acquires the work amount information acquired by the acquisition unit (for example, the numerical value of the work performed in the entire work process, the embedding of 100 cubic meters, etc.) and the total work amount information of the corresponding work process. Based on the above, a work process in which all of the work processes are not completed is specified, and the ratio of the work amount information of the work process to the total work amount information is obtained. In step S23, the CAD information generation unit specifies a three-dimensional object included in the CAD information including the object identifier corresponding to the process identifier based on the process identifier extracted by the process management unit, and specifies the specified three-dimensional A work amount ratio reflecting three-dimensional object reflecting the above-mentioned ratio from three-dimensional objects in which all work processes are not completed among objects (for example, if 10% completion, 10% capacity, area, high 3) a generated work volume ratio reflecting 3D object and the specified 3D object in which all the work processes are not completed are generated. Process management compatible CAD information including a three-dimensional object other than the object is generated. Finally, in step S24, the three-dimensional output control unit 114 (CAD software module or the like) draws the structure defined by the process management-compatible CAD information on the display unit 160. According to this flow, it becomes possible to generate process management-compatible CAD information including a work volume ratio reflecting three-dimensional object according to the progress of work, and draw a structure more accurately reflecting the actual work, A model can be generated.

FIG. 9 is a schematic diagram for explaining a technique for reflecting the ratio of work processes. First, each work process is associated with total work amount information corresponding to the total work amount of the work process. Specifically, in the process management data PMD 11-2, each work process "filling work P1-1", "slope shaping work P2-1", "roadwork work P3-1", "road work P4-1". Are associated with total work amount information, which is the work physical amount of the entire work process, which is 6000 cubic meters of earth pile, 50000 square meters of slope work, 7800 square meters of road construction, and 7800 square meters of road construction. At this time, as shown in the figure, when PQ1-1 (volume 3000 m) is acquired as work amount information,
(Volume 3000 cubic meters / total working physical quantity 6000 cubic meters)
Therefore, the ratio is obtained as 50% (1/2). Therefore, from the extracted and generated object embedding EL11-1, a work amount ratio reflecting three-dimensional object embedding EL11-1-H corresponding to the work end ratio 50% is synthesized and deformed by a known CAD composition / deformation technique. , Or replace it with the synthesized, deformed, or generated one. If the output is 1500 cubic meters, the ratio is 25% (1/4), and CAD information including a work volume ratio reflecting three-dimensional object synthesized, deformed, and generated by this apparatus according to the ratio is generated. Of course, in a plurality of work processes, it is possible to generate CAD information including each work amount ratio reflecting three-dimensional object having a size corresponding to the ratio of the work volume of the work process in the entire work process. By doing so, it becomes possible to obtain a three-dimensional object corresponding to the detailed end stage / end situation of each work process. At this time, in the deformation and generation according to the ratio, basically, when the unit of the work amount is the capacity, a rule for cutting the upper side while leaving the lower part (that is, forming from the lower part of the target object). When the unit of work amount is an area, it is preferable that a predetermined work start point and work start line are set and a rule formed from the points and lines is used. Note that a technique for identifying and carrying out a work end location (position, portion) almost faithfully to the volume location by a positioning device such as a GPS device will be described in detail later.

  FIG. 10 is a schematic diagram illustrating a technique for reflecting the ratio of work processes. First, each work process is associated with total work amount information corresponding to the total work amount of the work process. Specifically, in the process management data PMD11-3, each work process “filling construction P1-1”, “slope shaping construction P2-1”, “roadwork construction P3-1”, “road construction P4-1”. Are associated with total work amount information, which is the work physical amount of the entire work process, which is 6000 cubic meters of earth pile, 50000 square meters of slope work, 7800 square meters of road construction, and 7800 square meters of road construction. At this time, as shown in the figure, when PQ1-2 (volume 6000 cubic meters) is acquired as the work amount information, the work end ratio is 100%. In this case, the completed object is extracted as it is to be included in the CAD information.

Next, when PQ2-1 (volume output 40000 square meters) is acquired as the work amount information, the work end ratio is 80%.
(Production volume 4000 square meters / slope area 5,000 square meters, which is the total work physical quantity)
Therefore, the ratio is obtained as 80% (4/5). Therefore, from the extracted and generated object slope reinforcing concrete EL12, a work amount ratio reflecting three-dimensional object slope reinforcing concrete EL12-H corresponding to the work completion ratio of 80% is synthesized by a known CAD composition / deformation technique. , Deform and generate, and replace with this synthesized, deformed and generated. By doing so, it is possible to obtain an object corresponding to the detailed end stage / end situation of each work process.

  FIG. 11 is a flowchart illustrating generation of an object according to a work ratio using a GPS device as an example of processing executed by the CAD information generation device according to the first embodiment. In step S31, the entire work amount information corresponding to the entire work amount of the work process (for example, the earth work 3000 cubic m, the slope work of 40000 square meters, which is the work physical amount of the entire work process) is associated with the work process. . Next, in step S32, a work position acquired by a worker related to the work process or a GPS device (for example, a heavy machine having a GPS device, a worker having a mobile phone device including a GPS function) attached to the device. The work amount information of the work process including the information is acquired. Next, in step S33, the process management unit acquires the work amount information acquired by the acquisition unit (for example, the numerical value of the completed work performed in the entire work process, 100 cubic meters of earth pile, and the like) Based on the above, a work process in which all of the work processes are not completed is specified, and the ratio of the work amount information of the work process to the total work amount information is obtained. In step S34, when the position information for a work process corresponding to a three-dimensional object for which all work processes have not been completed among the identified three-dimensional objects has been acquired, from the non-finished three-dimensional object, A work amount ratio and position information reflecting three-dimensional object reflecting the ratio and the position information is generated, and the generated work amount ratio and position information reflecting three-dimensional object and all the work steps of the specified three-dimensional object are all. Process management-compatible CAD information including non-finished three-dimensional objects is generated. Finally, in step S35, the three-dimensional output control unit 114 (CAD software module, etc.) Is drawn on the display unit 160. According to this flow, it is possible to generate CAD information corresponding to the process management including the work amount ratio and position information reflecting three-dimensional object according to the work progress status and the work position information, and more accurately reflect the actual work situation. It is possible to draw a structure and generate a model.

  FIG. 12 is a schematic diagram for explaining a technique for reflecting the ratio of the work process and the work position. First, each work process is associated with total work amount information corresponding to the total work amount of the work process. Specifically, in the process management data PMD11-4, each work process “filling construction P1-1”, “slope shaping construction P2-1”, “road construction P3-1”, “road construction P4-1”. Are associated with total work amount information, which is the work physical amount of the entire work process, which is 6000 cubic meters of earth pile, 50000 square meters of slope work, 7800 square meters of road construction, and 7800 square meters of road construction. At this time, as shown in the figure, when PQ1-2 (volume 6000 cubic meters) is acquired as the work amount information, the work end ratio is 100%. In this case, the completed object is extracted as it is to be included in the CAD information.

Next, when PQ2-1 (volume output 40000 square meters) is acquired as the work amount information, the work end ratio is 80%.
(Production volume 4000 square meters / slope area 5,000 square meters, which is the total work physical quantity)
Therefore, the ratio is obtained as 80% (4/5). Therefore, from the extracted and generated object slope reinforcing concrete EL12, a work amount ratio reflecting three-dimensional object slope reinforcing concrete EL12-H corresponding to the work completion ratio of 80% is synthesized by a known CAD composition / deformation technique. , Deform and generate, and replace with this synthesized, deformed and generated. By doing so, it is possible to obtain an object corresponding to the detailed end stage / end situation of each work process.

Next, when PQ3-1 (volume output 6240 square meters) is acquired as the work amount information, the work end ratio is 80%.
(Production volume 6240 square meters / road work area 7800 square meters, which is the total work physical quantity)
Therefore, the ratio is obtained as 80% (4/5). In the technique prior to this embodiment, the object generated as the construction completed among the objects is generated according to a certain predetermined rule, but does not necessarily reflect the construction progress accurately. For example, normally, construction from the north side may be started from the south side, or the construction site may be changed flexibly according to the situation at the site. Therefore, in this embodiment, a technique is used in which the work location information including work position information acquired by the GPS device is used to reflect the already worked location in the object or CAD information as being closer to the situation at the site. explain.

  As shown in FIG. 12, for the roadwork P3, the work amount information including the position information LI10 is acquired. This apparatus generates an object including a range including the locus of the work position that is the position information LI10. That is, when the object path EL13 and the position information LI10 are overlapped to generate a work amount ratio and position information reflecting three-dimensional object, it is generated from the original object so that the position is preferentially left. , Make corrections. This is a work amount ratio and position information reflecting three-dimensional object, and by generating process management-compatible CAD information including this, it is possible to obtain an object path EL13-1-H that also reflects the work position.

  FIG. 13 is a schematic diagram illustrating a technique for reflecting the work position of the work process. As shown in the figure, there may be object road bodies EL20 and EL21 associated with the same process identifier and object identifier KK780. In such a case, when the process identifier (object identifier) KK780 is used as the search key as the work amount information, it is unclear which work process of the two objects may be selected and extracted. In such a case, the present apparatus has a positioning device (for example, a heavy machine having a GPS device, a work having a mobile phone device having a GPS function) attached to a worker or a device related to a work process in the work amount information. When the CAD information generation unit includes a plurality of three-dimensional objects associated with the same object identifier among the specified three-dimensional objects (that is, the same process identifier is included). When a plurality of associated work steps are included), a three-dimensional object that does not correspond to the position information is excluded based on the position information (that is, a three-dimensional object related to the position information is left). As described above, by utilizing the work position information, it is possible to obtain CAD information appropriately reflecting the work situation even in the case of CAD information and process management data having a plurality of the same identifiers. .

  FIG. 14 is a schematic diagram of a river structure in which 3D CAD data generated and processed by the apparatus or program according to Embodiment 1 is output by a 3D printer. As shown in the figure, the three-dimensional object OB50 is a completed river structure, and the 3D CAD data generated and processed by this apparatus or program can output a river structure at the construction stage according to an arbitrary volume. Is possible. In this example, the process of placing the anchored shaft into the first natural stone (the first layer process) is completed, and the filling material (crushed stone), which is the intermediate stage of the second layer process, is 50%. A schematic diagram is shown in which a three-dimensional object OB51 of a river structure in a finished state is output by a three-dimensional printer. As described above, according to the embodiment of the present invention, it is possible to output such a complicated structure at an arbitrary end ratio of an arbitrary process.

  FIG. 15 is a diagram showing the internal structure of a certain object. As shown in the figure, the color and pattern of the reinforcing bars RFst arranged horizontally as pattern data are pasted on the surface of the object SLmdl-n created in a certain work process. The three-dimensional object included in the CAD information of this apparatus can be associated with pattern data indicating its internal structure, and can be pasted on the surface of the three-dimensional object as necessary. In particular, when the object is in the middle of work, by pasting such pattern data, the internal structure can be shown at the same time as the situation during the work process. The user can easily understand the internal structure (in this example, the situation of the arranged reinforcing bars) by looking at the pattern drawn on the object surface of the three-dimensional model. The reinforcing bars RFst disposed horizontally as the pattern data can be attached to the side surface instead of the upper surface.

  FIG. 16 is a diagram showing the internal structure of a certain object. As shown in the figure, the surface of an object SLmdl-n created in a certain work process is configured as an object SLmdl-n1 pasted with another pattern data. As pattern data, the color, pattern, and shape of the reinforcing bars RFbar arranged vertically are pasted to form protrusions. Further, a reinforcing bar symbol RFbar-txt is pasted as a symbol, which describes “D22- @ 200” which is a symbol used by those skilled in the art. This means that 200 rebars with a diameter of 22 mm are laid, and those skilled in the art can easily understand the members. After molding the 3D model, the user can easily draw the 3D model and see or touch the 3D formed “projection” or “symbol” to easily shape the internal structure of the cutting part and the shape of the internal space. It becomes possible to understand the spatial composition such as room layout. In FIG. 15 and FIG. 16, it is also possible to use a barcode instead of the pattern or to attach the pattern to the side surface. A pattern such as a barcode can be visually observed or read by a barcode reader such as a portable terminal. It is also possible to read this additional information by accessing this system from a portable terminal.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, the processes and functions included in each unit and each step can be rearranged so as not to be logically contradictory, and a plurality of means / units and steps can be combined or divided into one. Is possible. Alternatively, it should be noted that some components, functions, processes, steps, etc. of the apparatus, method, program, etc. according to the present invention can be located in a remote server or the like. In each embodiment, a three-dimensional object is used as CAD information. However, it should be noted that the same effect can be obtained by associating with a line (straight line, curve) that is a two-dimensional object.
