  [Invention 2] Further, the completed type confirmation system according to Invention 2 is the completed type confirmation system according to Invention 1, wherein the structure is a structure configured by combining a plurality of building materials having a plane or a curved surface in the surface direction. is there.

  With such a configuration, the predicted shape output means outputs a predicted shape of a structure configured by combining a plurality of building materials having a plane or a curved surface in the surface direction so as to be compared with the reference shape.

  [Invention 3] Further, the completed type confirmation system of Invention 3 is the completed type confirmation system according to any one of Inventions 1 and 2, wherein the point cloud data is measured on the surface of the completed type using a three-dimensional laser scanner.

  When the surface of the finished mold is measured by the total station, the surface corresponding to the finished mold surface is estimated as a plane passing through a predetermined portion (for example, three points) of the finished mold. For this reason, when the finished mold is distorted or the surface is uneven, there is a possibility that an appropriate surface cannot be estimated. On the other hand, when measurement is performed using a three-dimensional laser scanner, for example, the least square method can be used to estimate the surface having the smallest error from multiple points on the surface of the finished mold, so that the finished mold is distorted. Even if the surface is uneven or the surface is uneven, a relatively appropriate surface can be estimated.

If the point at the specific position on the finished surface is known, the position of the predicted shape can be corrected from the positional relationship between that point and the reference point corresponding to the point at the specific position on the design plan surface.

  The predicted shape whose position is corrected is output by the predicted shape output means so as to be comparable with the reference shape.

  Here, the point data may be actual measurement data of the finished surface or its secondary data (for example, data calculated, processed, and generated based on the actual measurement data). Data obtained by measuring the surface of the finished mold using is included.

Then, the deviation amount calculation means outputs, for each design plan plane, multiple points corresponding to the design plan plane in an output mode corresponding to the deviation amount to the design plan plane calculated for the design plan plane.

Steps.

  As described above, according to the completed type confirmation system of the invention 1, by applying the structure model to the estimated surface so that the estimated surface matches the design plan surface corresponding to the estimated surface of the structure model. Since the predicted shape of the structure is formed and the predicted shape is output so as to be able to be compared with the reference shape, the overall predicted completed shape can be grasped from the completed completed mold. Therefore, since it is possible to perform adjustment in consideration of the overall finish, it is possible to obtain an effect that a structure can be constructed without impairing the overall design as compared with the conventional case.

  Furthermore, according to the completed type confirmation system of the fifth aspect, since multiple points are output in an output mode corresponding to the deviation amount between the surface of the completed mold and the design plan plane, the deviation of the completed model with respect to the structure model is grasped. be able to. Therefore, since adjustment in consideration of the overall finish can be performed, an effect that a structure can be constructed without impairing the overall design is obtained.

  On the other hand, according to the work type confirmation program of the invention 9 or the work form confirmation method of the invention 10, the same effect as the work type confirmation system of the invention 1 can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 to FIG. 15 are diagrams showing an embodiment of a work type confirmation system, a work type confirmation program, and a work type confirmation method according to the present invention.

  First, a design structure to which the present invention is applied will be described.

  FIG. 1 is a view of the wall 10 looking down from above.

  FIG. 2 is a front view of the wall 10.

  In the present embodiment, a wall 10 that reproduces a wall composed of a curved surface and an inclination is constructed by using the work type confirmation system, the work type confirmation program, and the work type confirmation method according to the present invention as a design structure. It applies to the case.

  As shown in FIGS. 1 and 2, the wall 10 is configured by slightly tilting the surface of the PCa plate 12 backward, stacking four PCa plates 12 in the vertical direction, and further connecting a large number in the horizontal direction. . When the wall 10 is viewed from above, a curved shape is formed, and the beauty of the curve is expressed as a whole.

  FIG. 3 is a diagram showing a construction process of the wall 10.

  As shown in FIG. 3, the wall 10 has a structure in which an RC column 14 is fastened to a joint position of the PCa plate 12 after the PCa plate 12 is temporarily fixed at a predetermined position. It is a special structure in which the plate 12 is a beam and a wall. Furthermore, since four such structures are stacked in the vertical direction, it is difficult to construct according to the design book as compared to a normal structure. This is true for all of the structural structures that are designed.

  FIG. 4 is a diagram showing a case where the front surface of the first layer of the wall 10 is measured using the three-dimensional laser scanner 200.

  In the present embodiment, as shown in FIG. 4, when the construction of the first layer (bottom stage) of the wall 10 is completed, the finished surface of the first layer is formed using the three-dimensional laser scanner 200. Measurement is performed, and the completed molds of the second to fourth layers are simulated by the completed mold confirmation apparatus 100 based on the measurement result. Refer to the simulation result, confirm whether it is within the allowable error range, the position and inclination of the PCa plate 12 with respect to the first layer finished mold or in the construction of the second to fourth layers Can be adjusted. Thereby, since construction can be advanced while also taking into consideration untreated parts, the wall 10 can be constructed without impairing the overall design.

  The three-dimensional laser scanner 200 measures the distance to the object with a predetermined resolution within the measurement range, generates point group data indicating the coordinates of each measurement point based on the measured distance, and stores it in the memory. Each measurement point is given coordinates of a three-dimensional orthogonal coordinate system (hereinafter referred to as a scanner coordinate system) with the current position of the three-dimensional laser scanner 200 as the origin. By using point cloud data, it is possible to visualize the reflection intensity of different lasers in accordance with the material of each measurement point in gray scale, and it is possible to easily calculate the size of the structure, the degree of inclination, and the like. Thus, according to the three-dimensional laser scanner 200, the three-dimensional information of the object existing in the measurement range can be acquired at high speed and with high density.

  The measurement principle of the three-dimensional laser scanner 200 is similar to that of the total station, and the distance r calculated from the time until the laser pulse emitted toward an arbitrary target (measurement point p) is reflected and returned is measured. To do.

  The coordinates of the measurement point p can be calculated by converting the coordinates (r, λ, φ) of the three-dimensional polar coordinate system into the coordinates (x0, y0, z0) of the scanner coordinate system. Here, φ is an angle formed by the z-axis and the laser beam, and λ is an angle formed by the x-axis and the laser beam.

  Next, the configuration of the completed type confirmation apparatus 100 will be described.

  FIG. 5 is a block diagram showing a hardware configuration of the completed type confirmation apparatus 100.

  As shown in FIG. 5, the work type confirmation device 100 reads from the CPU 130 that controls the calculation and the entire system based on the control program, the ROM 132 that stores the control program of the CPU 130 in a predetermined area, the ROM 132, and the like. And a RAM 134 for storing calculation results required in the calculation process of the CPU 130 and an I / F 138 that mediates input / output of data to / from an external device. They are connected to each other via a bus 139 which is a signal line for transfer so that data can be exchanged.

  The I / F 138 includes, as external devices, an input device 140 such as a keyboard and a mouse that can input data as a human interface, a storage device 142 that stores data, tables, and the like as files, and a screen based on image signals. , A three-dimensional laser scanner 200, and a total station 300 are connected.

  The storage device 142 stores CAD data related to a structure model indicating a shape serving as a reference of the wall 10. The structure model is expressed in a three-dimensional orthogonal coordinate system (hereinafter referred to as a global coordinate system) having a reference point Pg at the construction site as an origin. CAD data is vector data that represents a structure model with lines connecting points in the global coordinate system. The shape line of the structure model, the attributes (point names and positions) of the end points of the street core, and the shape line The attributes (name, position and length of the line) and the attributes of the design plan surface (name, position and size of the surface) of the structure model are defined. In addition, a surface formed of a triangle or a rectangle is defined as the smallest model. The CAD data can be described in VRML, for example. Although a structure model can be expressed in a three-dimensional orthogonal coordinate system defined on CAD software, in this case, it is necessary to convert to a global coordinate system when using CAD data.

  Next, processing executed by the CPU 130 will be described.

  The CPU 130 is composed of a microprocessing unit or the like, and activates a predetermined program stored in a predetermined area of the ROM 132, and executes a result confirmation process and a deviation state display process shown in the flowcharts of FIGS. 6 and 12 according to the program. To do.

  First, the completed type confirmation process will be described.

  FIG. 6 is a flowchart showing the completed type confirmation process.

  FIG. 7 is a diagram for explaining a case where the finished surface of the wall 10 is measured.

  The completed type confirmation process is a process of simulating the completed types of the second to fourth layers based on the measurement result of the three-dimensional laser scanner 200.

  Prior to the execution of the completed mold confirmation process, the surface of the completed mold of the first layer is measured using the three-dimensional laser scanner 200. Since the wall 10 is large and the entire surface cannot be measured by one measurement, as shown in FIG. 7, a plurality of measurement points P0 to Pn are set around the wall 10, and the first is measured for each measurement point P0 to Pn. By measuring a part of the surface of the finished mold of the layer, the entire surface of the finished mold of the first layer is measured.

  Specifically, measurement is performed at each measurement point P0 to Pn as follows.

  FIG. 8 is a front view of the target 26.

  FIG. 9 is a diagram illustrating a case where the front surface of the completed mold of the wall 10 is measured using the three-dimensional laser scanner 200.

  First, as shown in FIGS. 8 and 9, a plurality of targets 26 (target seals) are attached to the surface of the finished mold. At this time, the target 26 may be installed using a tripod or the like behind the three-dimensional laser scanner 200 and within the scanning range thereof.

  Next, the coordinates of the reference point Pg are given to the total station 300, and the center point of each target 26 is measured using the total station 300. As a result, first point cloud data indicating the coordinates of the global coordinate system is obtained for each measurement point and stored in the memory of the total station 300.

  Then, using the three-dimensional laser scanner 200, the finished surface including the center point of each target 26 is measured. As a result, second point group data indicating the coordinates of the scanner coordinate system for each measurement point is obtained and stored in the memory of the three-dimensional laser scanner 200.

  When the completion type confirmation process is executed in the CPU 130 after the measurement is completed, as shown in FIG. 6, first, the process proceeds to step S100, and the first point group data for each of the measurement points P0 to Pn is stored in the total station 300. The second point group data for each of the measurement points P0 to Pn is input from the three-dimensional laser scanner 200, and the process proceeds to step S102.

  In step S102, a measurement point corresponding to the center point of each target 26 is extracted from the input second point group data, and the coordinates of the extracted measurement point are set to the corresponding measurement point of the input first point group data. By replacing the coordinates with the coordinates, a coordinate conversion process for converting the coordinates of the second point cloud data into the global coordinate system is executed. The coordinate conversion process is performed for each measurement point P0 to Pn.

  Next, the process proceeds to step S104, where each measurement point converted into the coordinates of the global coordinate system is displayed on the display device 144 to display the surface image of the first layer, and the process proceeds to step S106. The measurement point group corresponding to one PCa board 12 is selected from the displayed measurement point group by the input device 140, and the process proceeds to step S108.

  In step S108, based on the coordinates of the selected measurement point group, in the global coordinate system, a plane corresponding to the surface of the finished mold of the first layer is estimated. As a plane estimation method, for example, a least square method, a Hough transform, or other methods can be employed. When the least square method is employed, a plane that minimizes the sum of squares of the distances from the respective measurement points to the plane for the selected measurement point group is obtained as the estimation plane.

  When the four corners of the PCa plate 12 are measured by the total station 300, the plane corresponding to the surface of the PCa plate 12 is estimated as a plane passing through the four corners. Therefore, when the PCa plate 12 is distorted or has irregularities on the surface, there is a possibility that an appropriate plane cannot be estimated. On the other hand, when the measurement is performed using the three-dimensional laser scanner 200, the plane on which the error is minimized is estimated from the point group on the surface of the PCa plate 12, so that the PCa plate 12 is distorted or uneven on the surface. Even if there is, a relatively appropriate plane can be estimated.

  Next, the process proceeds to step S110, the CAD data is read from the storage device 142, and the process proceeds to step S112.

  In step S112, the predicted shape of the wall 10 is formed from the structure model based on the read CAD data. In the global coordinate system, the predicted shape is first to first with respect to the estimated plane so that the estimated plane estimated in step S108 matches the design plan surface of the first layer corresponding to the estimated plane in the structure model. It is formed by fitting the design plan surface of the fourth layer. Regarding the correspondence between the estimated plane and the design plan plane of the first layer, for example, the design plan plane with the smallest distance from the estimated plane can be associated among the design plan planes of the first layer.

  Next, the process proceeds to step S114, and based on the read CAD data, the design plan planes of the first to fourth layers corresponding to the predicted shape in the structure model are formed as the reference shape in the structure model.

  Next, the process proceeds to step S116, and point data indicating the coordinates of a point at a specific position on the surface of the first-layer finished mold is input from the total station 300.

  FIG. 10 is a diagram showing a case where the front surface of the first layer of the wall 10 is measured using the total station 300.

  As shown in FIG. 10, using the total station 300, a point pa at a specific position on the surface of the PCa plate 12 in the first layer finished mold is measured.

  The total station 300 measures the distance to the point pa, generates point data indicating the coordinates of the measurement point pa based on the measured distance, and stores it in the memory. Since the total station 300 is advantageous in that it can measure a point at a specific position with respect to the three-dimensional laser scanner 200, the point data input in step S116 is highly accurate by measuring using the total station 300. Can be obtained at In step S116, point data may be input from the first point cloud data.

  Next, the process proceeds to step S118, and the position of the predicted shape formed in step S112 is corrected based on the coordinates of the measurement point pa converted to the global coordinate system.

  FIG. 11 is a diagram illustrating a case where the position of the predicted shape is corrected.

  In step S108, the plane corresponding to the completed surface is estimated. However, since the plane is estimated only from the point cloud, it is difficult to completely match the design plan plane with the estimated plane (finished surface). Deviation occurs in the surface direction. Therefore, in order to realize high prediction accuracy, it is necessary to correct the position of the design plan surface to be matched.

  First, since the lower side of the first layer of the finished mold should be grounded, the predicted shape 16 is moved so that the lowermost side of the predicted shape 16 is located on the ground plane as shown in FIG. Let

  Next, as shown in FIG. 11B, the measurement point pa and the reference point corresponding to the measurement point pa on the first layer surface of the predicted shape 16 (applied with the design plan surface of the first layer). The predicted shape 16 is moved so that pb matches or substantially matches. Here, “substantially coincidence” refers to a case where the measurement point pa and the reference point pb do not coincide with each other. For example, when the distance between the measurement point pa and the reference point pb is equal to or less than a predetermined value, or the measurement point pa and the reference point pb. It is conceivable that the distance of is minimum. Since the position of the point pa on the surface of the PCa plate 12 is known, the coordinates of the reference point pb on the design plan surface can be specified in advance.

  In addition, when correcting the position of the predicted shape, the predicted shape is moved so that the lowermost side of the predicted shape is positioned on the ground plane. However, the present invention is not limited to this, and the movement to the ground plane is not performed. The predicted shape may be moved so that the measurement point pa and the reference point pb match or substantially match.

  When the construction of the second layer of the wall 10 is completed, the measurement point pa of the second layer is used as a reference. That is, the measurement point pa of the highest layer among the finished molds is used as a reference for position correction.

  Next, the process proceeds to step S120, where the predicted shape and the reference shape formed in steps S112 and S114 are combined and displayed on the display device 144, and a series of processes is terminated and the original process is restored.

  Next, the shift state display process will be described.

  FIG. 12 is a flowchart showing the shift state display process.

  The deviation state display process is a process for displaying the state of deviation of the completed model with respect to the structure model based on the measurement result of the three-dimensional laser scanner 200. When executed in the CPU 130, as shown in FIG. First, the process proceeds to step S200.

  In steps S200 and S202, processing similar to that in steps S100 and S102 is executed, and the process proceeds to step S204.

  In step S204, each measurement point converted into coordinates in the global coordinate system is made to correspond to the design plan plane.

  FIG. 13 is a diagram illustrating a case where each measurement point is associated with a design plan surface. FIG. 4A is a perspective view of the design plan surface, and FIG. 4B is a schematic plan view of the design plan surface.

  Here, a case where each measurement point of two adjacent PCa plates 12 is made to correspond to the design plan surface will be described.

  When the point cloud data is obtained by a plurality of measurements (FIG. 7) or when the deviation of the finished mold with respect to the structure model is large, as shown in FIG. 13, it corresponds to one PCa plate 12 in the structure model. It becomes difficult to determine which measurement point distributed near the boundary between the design plan surface 22 and the design plan surface 24 corresponding to the other PCa plate 12 corresponds to the design plan surface 22 or 24. If this determination is inappropriate, it is not possible to properly grasp the state of deviation of the finished mold with respect to the structure model.

  Therefore, each measurement point of the two PCa plates 12 is made to correspond to one of the design plan surfaces 22 and 24 with the section plane 20 as a reference. The section plane 20 is defined as a plane that passes through the boundary between the design plan planes 22 and 24 and is along a bisector of an angle formed by the normal planes 22a and 24a of the design plan planes 22 and 24. Specifically, the measurement points distributed on the design plan plane 22 side from the section plane 20 correspond to the design plan plane 22, and the measurement points distributed to the design plan plane 24 side from the section plane 20 correspond to the design plan plane 24, respectively. Let

  Next, the process proceeds to step S206, and a deviation amount from the measurement point to the design plan surface 22 is calculated for each measurement point corresponding to the design plan surface 22 in the global coordinate system, and is made to correspond to the design plan surface 24. For each measured point, a deviation amount from the measured point to the design plan plane 24 is calculated.

  Subsequently, the process proceeds to step S208, and the shapes of the design plan surfaces 22 and 24 are displayed on the display device 144. Then, a part of the design plan surface 22 where the calculated deviation amount is equal to or greater than a predetermined value (a part corresponding to the measurement point) is displayed in the first color (for example, red), and the other part is displayed in the second color (for example, gray). Is displayed. Similarly, a part of the design plan surface 24 where the calculated deviation amount is a predetermined amount or more (a part corresponding to the measurement point) is displayed in the first color, and the other part is displayed in the second color. If necessary, the image may be displayed using a third color in consideration of the direction of displacement (for example, one is red and the other is blue).

  Next, the process proceeds to step S210, where it is determined whether or not the processes of steps S206 and S208 have been completed for all the design plan planes in the first layer, and the processes have been completed for all the design plan planes in the first layer. When it is determined that the process has been completed (Yes), the series of processes is terminated and the original process is restored.

  On the other hand, when it is determined in step S210 that the process has not been completed for all the design plan planes in the first layer (No), the process proceeds to step S206.

[Operation of the present embodiment]
Next, the operation of the present embodiment will be described.

  First, the case of simulating the finished molds of the second to fourth layers will be described.

  First, at the plurality of measurement points P0 to Pn, the surface of the first layer is measured using the three-dimensional laser scanner 200. As a result, the point cloud data for each measurement point P0 to Pn is stored in the memory of the three-dimensional laser scanner 200.

  Next, a work type confirmation process is executed in the work type confirmation apparatus 100.

  In the completed type confirmation apparatus 100, when the completed type confirmation process is executed, the point group data for each measurement point P0 to Pn is input from the three-dimensional laser scanner 200 through steps S100 to S104, and the input point group is received. Based on the data, the coordinates of each measurement point are converted into the coordinates of the global coordinate system, and a first-layer-type surface image is displayed.

  Here, a measurement point group corresponding to one PCa plate 12 is selected from the displayed measurement point group.

  In the completed type confirmation apparatus 100, when a measurement point group is selected, a plane is estimated based on the coordinates of the selected measurement point group through steps S108 to S114, and a predicted shape and a reference shape are determined based on CAD data. It is formed. Next, through steps S116 and S118, the position of the predicted shape is corrected based on the point data.

  FIG. 14 is a diagram showing simulation results of the finished molds of the second to fourth layers. FIG. 4A is a cross-sectional view of the predicted shape 16 and the reference shape 18, and FIG. 4B is a front view of the predicted shape 16 and the reference shape 18.

  Then, through step S120, as shown in FIGS. 14A and 14B, the predicted shape 16 and the reference shape 18 are synthesized and displayed. In the example of FIG. 14 (a), if the construction is proceeded as it is, the position and inclination of the finished shape of the wall 10 will be different from those of the structure model, and there is a possibility that the overall design may be greatly affected. I can grasp it. In addition, you may display the deviation | shift amount of the estimated shape 16 with respect to the reference | standard shape 18 by a numerical value for every layer.

  Next, a description will be given of a case where the state of deviation of the finished mold with respect to the structure model is displayed.

  Similarly to the above, after measuring the surface of the first layer of the finished mold using the three-dimensional laser scanner 200, the finished mold confirmation apparatus 100 executes a shift state display process.

  In the completed type confirmation apparatus 100, when the deviation state display process is executed, the point group data for each measurement point P0 to Pn is input from the three-dimensional laser scanner 200 through steps S200 and S202, and the input point group is received. Based on the data, the coordinates of each measurement point are converted into coordinates in the global coordinate system.

  FIG. 15 is a diagram illustrating a display result of the shift state.

  Next, through steps S204 and S206, the coordinate-converted measurement points are made to correspond to the design plan surface, and the deviation amount from the measurement point to the design plan surface is measured for each measurement point corresponding to the design plan surface. Calculated. Then, after step S208, as shown in FIG. 15, the portion where the calculated deviation amount is not less than a predetermined value is displayed in the first color and the other portions are displayed in the second color. If necessary, the image may be displayed using a third color in consideration of the direction of displacement (for example, one is red and the other is blue).

[Effect of this embodiment]
In this way, in the present embodiment, point cloud data obtained by measuring the surface of the first mold is input, and the surface of the completed mold is handled based on the input point cloud data. The estimated plane is estimated based on the CAD data in the storage device 142, and the estimated plane estimated in the global coordinate system matches the design plan plane of the first layer corresponding to the estimated plane in the structure model. By applying the design plan planes of the first to fourth layers to the estimated plane, the predicted shape of the wall 10 is formed. Based on the CAD data of the storage device 142, the structure model Of these, the first to fourth design plan planes corresponding to the predicted shape are formed as reference shapes, and the predicted shape and the reference shape are combined and displayed.

  Thereby, the predicted shape of the second to fourth layers is formed by fitting the structure model to the estimated plane so that the estimated plane and the design plan plane corresponding to the estimated plane among the structure models match, Since the predicted shape and the reference shape are combined and displayed, the overall predicted completed shape can be grasped from the completed completed shape. Therefore, since the adjustment can be performed gradually over a plurality of layers and the overall finish can be taken into consideration, the structure can be constructed without impairing the overall design as compared with the conventional case.

  In addition, by combining the actual measurement of the finished surface and the simulation, higher prediction accuracy can be realized as compared with the case where only the simulation is performed.

  Furthermore, in this Embodiment, it applied when confirming the completed type of the wall 10 comprised by combining multiple PCa board 12 in the surface direction.

  As a result, a design structure can be constructed without impairing the overall design.

  Further, in the present embodiment, point cloud data obtained by measurement using the three-dimensional laser scanner 200 is employed.

  Thereby, even when the PCa plate 12 is distorted or has irregularities on the surface, a relatively appropriate plane can be estimated.

  Furthermore, in this embodiment, point data obtained by measuring a point at a specific position on the surface of the first-layer finished mold is acquired, and the position of the predicted shape is corrected based on the acquired point data. .

  Thereby, since the position of the predicted shape is corrected, the overall predictable pattern can be grasped more appropriately.

  Furthermore, in the present embodiment, the section plane 20 that passes through the boundary between the design plan planes 22 and 24 and is along the bisector of the angle formed by the normal planes 22a and 24a of the design plan planes 22 and 24 is provided. As a reference, the point cloud specified by the point cloud data is made to correspond to any one of the design plan surfaces 22 and 24, and the design plan is made from the measurement point for each measurement point corresponding to the design plan surface 22 in the global coordinate system. The amount of deviation up to the plane 22 is calculated, the amount of deviation from the measurement point to the design plan plane 24 is calculated for each measurement point corresponding to the design plan plane 24, and the measurement points corresponding to the design plan planes 22 and 24 are calculated. A portion of the group where the calculated deviation amount is a predetermined value or more is displayed in the first color.

  Thereby, since the measurement point group is displayed by color-coding according to the deviation | shift amount of the surface of a completed mold and a design plan surface, the shift | offset | difference of the completed mold with respect to a structure model can be grasped | ascertained visually. Therefore, since the adjustment in consideration of the overall finish can be performed, the structure can be constructed without impairing the overall design.

  In addition, since the point cloud corresponds to one of the design plan surfaces 22 and 24 with the section plane 20 as a reference, even a structure such as the wall 10 having a plurality of surfaces with different angles can be performed on the structure model. The displacement of the mold can be grasped relatively appropriately.

  Furthermore, since the location where the amount of deviation is greater than or equal to a predetermined value in the measurement point group corresponding to the design planning planes 22 and 24 is displayed in the first color, only the location where the amount of deviation is large can be grasped.

  In the above embodiment, the wall 10 corresponds to the structure of the invention 1, 2, 9 or 10, the CAD data corresponds to the structure model data of the invention 1, 9 or 10, and the storage device 142 corresponds to the invention.
