Hereinafter, a diagram checking support device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating an example of a configuration of a check check support device according to the present embodiment.

  As shown in FIG. 1, the inspection support apparatus 1 according to the present embodiment can include a control unit 10 that controls the whole thereof, and can include a storage unit 11 and a display unit 12.

  The control unit 10 can be realized by, for example, a CPU (Central Processing Unit), a working memory, a nonvolatile storage device, or the like, or an integrated circuit (Integrated Circuit). A control program executed by the CPU is stored in the storage device, and the CPU reads out the control program to the working memory and executes the control program, so that the function of the control unit 10 can be achieved. The control program may be, for example, a program for causing a CPU to execute processing relating to first and second controls described below.

  The control unit 10 is not limited to this example, and may have a function of controlling the entire inspection support apparatus 1 or a part necessary for the first and second controls. It should be noted that the check check support device 1 can also be realized by a general-purpose computer. Further, the above storage device can be used as a storage area of the storage unit 11. In addition, the inspection support apparatus 1 is not limited to the configuration in which the display unit 12 is incorporated, and may have a configuration in which a display device as the display unit 12 is connected to the outside of the main body of the inspection support apparatus 1.

  The storage unit 11 stores CAD data and image data obtained by imaging the CAD data. The image data may be data in which a coordinate value and a pixel value at the coordinate value are defined. The image data can be data obtained by converting CAD data into a file format for electronically saving an image to be printed on paper, such as Portable Document Format (PDF). Alternatively, the image data may be intermediate data obtained when the CAD data is printed. The control unit 10 may be configured to generate image data from the CAD data and control the image data to be stored in the storage unit 11.

  The storage unit 11 for storing the CAD data and the image data thereof may be provided in a server device such as a server computer connected to the inspection support device 1 via a network or the like. In other words, the CAD data and the like can be stored in a server device that is connected to the inspection support device 1 via a network or directly.

  In addition, when the storage device 11 is provided inside the inspection support device 1, the input device for inputting CAD data or the like to be stored in the storage unit 11 can be provided. When the storage unit 11 is provided externally, the inspection support apparatus 1 includes an input unit (reception unit) that receives and inputs CAD data and the like from the storage unit 11 for first and second control described below. Can be prepared.

  The control unit 10 executes first control and second control described below. Schematically, the first control is equivalent to control for generating inspection data, and the second control is based on two inspection data generated by the first control to be compared. This corresponds to control for causing the user to check the figure.

  First, an example of the first control will be described with reference to FIGS. 2 and 3. FIG. 2 is a flowchart for explaining an example of the generation processing of the inspection data in the inspection support apparatus 1. FIG. 3 is a concept showing an example of the inspection data generated by the generation processing of FIG. FIG.

  The first control includes, for a plurality of pieces of configuration information according to a predetermined rule, linking the coordinate values of the plurality of pieces of configuration information and grouping the plurality of pieces of configuration information as element information having coordinate values. It is executed according to the type rules (step S1).

  Here, the configuration information is configuration information included in the CAD data, and is exemplified by a value, a line, an attribute, and the like. However, the configuration information referred to here is information having coordinate values. For example, the above value indicates text to be drawn, and the above attribute indicates a reader to be drawn.

  In the grouping process, among the configuration information included in the CAD data, a plurality of configuration information according to a predetermined rule is searched, and the searched plurality of configuration information is converted to generate element information. Can be

  The predetermined rule includes, for example, a drafting rule (drawing rule), a rule relating to connectivity between elements represented by configuration information (graphic representation), and a rule relating to proximity of coordinates between elements represented by configuration information. And the like. Of course, a combination of two or more of these rules may be used as the predetermined rule. The rule regarding the connectivity between the elements can be defined, for example, by the fact that the elements are connected at least partially. The rule regarding the closeness of coordinates between elements can be defined, for example, by the distance between elements being shorter than a predetermined value.

  As described above, the grouping process is performed according to a plurality of types of predetermined rules. A plurality of types of drafting rules will be described as an example. For example, in the grouping process, among the drafting rules, elements such as lines and text (elements corresponding to the above-described configuration information, in other words, elements which are graphically represented by the above-described configuration information) are converted from dimensions, view names, and the like. Rules for composing (creating) elements can be employed. Elements such as lines and text, and elements such as dimensions and view names are as shown in FIG. 3, for example.

  Here, different types of predetermined rules are adopted for each constituent element. For example, in order to compose a dimension element, two lines indicating both ends of the object to be dimensioned, a line with an arrow placed between the lines, and text (numeric text indicating the dimension) are required. There is a rule that there is.

  Further, for example, a rule that only text of a font having a predetermined size or more is required to form an element of a view name can be given. It is preferable to include, in the grouping process, a conversion process for converting only one piece of configuration information into one piece of element information as a result, like the exemplified view name. In the following, such conversion processing in the case where the group includes only one configuration information will be described as a part of the grouping processing.

  In addition, not only one element information but also a plurality of element information obtained by grouping according to one rule can be present. Further, the coordinate value of the element information (the coordinate value of the element information) can be, for example, one of the coordinate values of a plurality of linked configuration information. The coordinate values of the element information may be, for example, lower left coordinates and upper right coordinates of a range (area) defined in the widest range among the plurality of pieces of configuration information. As described above, the coordinate value of the element information may be determined according to any rule, and the rule may be determined in advance.

  In the first control, among the pieces of element information obtained by the grouping, a plurality of pieces of element information are associated with each other to generate new element information, and perform multi-layer (layering) processing on the element information ( Step S2). The new element information generated here has coordinate values like the element information generated (converted) in the grouping process. For example, it is element information having coordinate values and indicating a cross-sectional view. Can be. The element information indicating the cross-sectional view can be referred to as cross-sectional view information. By step S2, one or a plurality of cross-sectional view information can be generated.

  In other words, the generation processing in step S2 links the coordinate values of a plurality of element information according to a predetermined rule, and groups the plurality of element information as new element information (such as cross-sectional view information) having the coordinate values. (Referred to as a second grouping process). Here, as the predetermined rule for generating cross-sectional view information, for example, among the drafting rules, a rule for forming a cross-sectional view from elements such as dimensions and view names, and a rule between those elements indicated by coordinate values. There is a rule that the distance is smaller than a predetermined value (that is, the distance between elements is short).

  Hereinafter, an example in which the element information generated in step S2 indicates a sectional view will be described. However, instead of the sectional view, for example, a detailed plan view or the like may be employed. If the comparison by the second control described later only needs to be performed on the element information obtained by the grouping in step S1, step S2 is not an essential control.

  The hierarchization processing in step S2 may be processing for associating the generated cross-sectional view information as a higher layer of the original element information. Also, from the viewpoint of hierarchies, the configuration information can be positioned as a lower layer of the element information, and it is preferable to make such an association. The layering is not limited to three layers, but may be N (N is a natural number of 2 or more) layers.

  As illustrated in FIG. 3, the cross-sectional view information 31, the dimension information 32 indicating the dimensions in the cross-sectional view indicated by the cross-sectional view information 31, the text information 33 in the dimension information 32, etc. 3 can be hierarchized. Further, such a hierarchization process can also be configured to be executed by a user operation for designating an element or the like and its hierarchy.

  In the first control, data of an area (corresponding portion) corresponding to the element information in the image data of the CAD data is linked to each element information of the CAD data using the coordinate value in the element information as a primary key. Then, data for a check is generated (step S3). For example, not only the element information such as the dimension information 32 obtained by grouping from the configuration information but also the cross-sectional view information 31 which is one of the element information may be linked to the data of the corresponding area in the image data. it can.

  The inspection data illustrated in FIG. 3 includes the entire image data 30 and the above-described element information and configuration information of the first to third levels, and these are hierarchically linked. In this case, the entire diagram 30 can be treated as, for example, layer 0. Here, cross-sectional view information 31 indicating a cross-sectional view of the element (part or the like) is associated with a region in the overall view 30 where a plan view or an external view of the element (part or the like) is displayed. Thus, when performing a check, it is possible to display the overall view 30 on the display unit 12 and to display the cross-sectional view information 31 when a selection operation for this area is received.

  The inspection data generated in step S3 relates the link between the CAD data and the image data, and links the cross-sectional view information 31 with the corresponding elements in the overall diagram 30 as illustrated in FIG. be able to. However, as described above, the link between the CAD data and the image data is not limited to this, and the control unit 10 uses the coordinate values of the element information as a primary key to convert the CAD data and the image data for each element information. Tied to Therefore, the inspection data includes the cross-sectional view information 31 and the corresponding image data, the element information such as the dimension information 32 and the corresponding image data, and the configuration information such as the text information 33 and the corresponding image data. , Can be linked to each other. In this way, by performing the above-described linking and layering, when performing the inspection, the hierarchically-viewed figure (cross-sectional view, etc. ), Element information, and configuration information can be confirmed by the user.

  The element information has the coordinate values as described above. If the origin of the coordinates in both the CAD data and the image data is shared at a predetermined position such as the lower left of the drawing, the element information in the image data is obtained. Are also known. The control unit 10 sets the two in such a state of being linked, and separately stores the data as inspection data in the storage unit 11, or sets one of the CAD data and the image data stored in the storage unit 11 to the other. Update to the linked state. In the latter case, the updated data will be treated as data for a check.

  In the second control, two inspection data generated by the first control for the two CAD data to be compared are linked for each element information with a value other than the coordinate value in the element information as a primary key. In the state shown in FIG. Further, the coordinate value in the element information is a value indicating the coordinates of the element information, and is a value determined in the process of grouping. In addition, the second control can be adapted to correspond to a drawing check operation other than the comparison.

  An example of a check processing for performing a check work will be specifically described with reference to FIG. FIG. 4 is a flowchart for explaining an example of a check process in which a check is performed using the check data generated in the generation process of FIG.

  First, the control unit 10 inputs the above two data for the check from the storage unit 11 (step S11), and determines what kind of check processing is to be performed (step S12). The determination in step S12 is based on the assumption that the control unit 10 receives a user operation from an operation unit (not shown) and follows the user operation. Note that the determination processing in step S12 can be performed before the input processing in step S11. In this case, only necessary data for the inspection, for example, only the inspection data related to the corrected drawing is input. In some cases, it may be necessary.

  When comparing a plurality of drawings, the control unit 10 performs a process of associating the inspection target data to be compared with each other (step S13). This association is performed by setting two (or more) inspection data to be compared for each element information in a state in which a value other than the coordinate value in the element information is used as a primary key. Next, the control unit 10 causes the display unit 12 to simultaneously display the inspection target data to be compared in such a state as to be linked to each other in order to allow the user to compare elements between the plurality of drawings (step S14). At this time, for example, if a check layer is superimposed on the inspection data and displayed, and a check box is provided for each element in that layer, the user can input the check result. The control unit 10 extracts, for example, unchecked elements and displays the results on the display unit 12 as a list (or prints them with a printing device (not shown)) (step S17).

  When checking the compatibility between the element and the drawing rule, the control unit 10 causes the display unit 12 to display the check target data to be checked (normally, the check data corresponding to the corrected drawing) for the check of the suitability. (Step S15). As described above, the inspection data can be viewed from the overall view of the appearance, with the hierarchical sectional view (cross-sectional view information), element information, and configuration information as it is or by following the hierarchy by user operation. Can be displayed in an appropriate state. Therefore, the user can easily confirm the compatibility between the element and the drawing rule.

  At this time, for example, if a check layer is superimposed and displayed on the inspection data and a check box is provided for each element to check whether the drawing rule is correct, the check result can be provided to the user. Can be entered. The control unit 10 extracts, for example, unchecked elements and displays the result on the display unit 12 as a list (step S17).

  When performing overlap inspection between elements in one drawing, the control unit 10 enlarges inspection drawing data to be inspected (normally, inspection drawing data corresponding to a corrected drawing) for overlap inspection, and the like. It is displayed on the display unit 12 (step S16). At this time, for example, if a check layer is superimposed and displayed on the inspection data and a check box is provided for each element to check whether the layer overlaps, the check result is input to the user. Can be done. The control unit 10 extracts, for example, unchecked elements and displays the result on the display unit 12 as a list (step S17).

A more specific example of the first control and the second control as described above will be described below.
FIG. 5 is a conceptual diagram illustrating an example of a process of associating and layering elements based on CAD data. FIG. 6 is a conceptual diagram showing an example of element information obtained by grouping, and FIG. 7 is a conceptual diagram showing an example of linking of the element information of FIG. 6 with image data. In FIGS. 5 to 7 and FIG. 8 to be described later, positions representing coordinates are indicated by “x”.

  As described above, in the first control, general-purpose information (configuration information) such as lines, values, attributes, and the like that are similarly present in different CAD data are grouped based on drafting rules, connectivity, and positional relationships. Converts to drawing element information (dimension information, cross-section information, etc.). Further, the elements are associated with each other based on the connectivity, positional relationship, and content of the element indicated by the element information to form a multilayer.

An example in which “geometric tolerance” is recognized as element information will be described with reference to FIG. 5 and the like.
On the CAD data exemplified in FIG. 5, the geometrical tolerance 50 is expressed by a plurality of pieces of configuration information constituting the geometrical tolerance. The geometrical tolerance 50 can include information indicating components such as TEXT, LEADER, and LINE, and respective coordinate values (for example, coordinates a, b, and c, respectively). As described above, all the constituent elements in the CAD data including the exemplified configuration information include the coordinate values indicating the respective coordinates. In the geometrical tolerance 50, TEXT includes four pieces of configuration information, and LINE also includes four pieces of configuration information corresponding to four sides.

  When grouping these pieces of configuration information into element information, the one that has text information of a tolerance symbol at the head and is surrounded by four lines (drafting rule) is recognized as a geometrical tolerance. From the configuration information group recognized in this way, it is possible to convert to the element information indicating the element 51 of the geometric tolerance, or to separately generate the element information indicating the element 51 of the geometric tolerance.

  Specifically, as illustrated in FIG. 6, the constituent elements are grouped and recognized as element information 61 called “geometric tolerance”, and data 60 indicating the element information is associated with the element information 61 in TEXT, LEADER. , LINE, and the like (coordinate x in this example). The data 60 can also include other element information as exemplified by the dimension information. As described above, the grouping method can be performed based on drafting rules, connectivity, proximity of coordinate values, and the like.

  Cross-sectional information indicating the cross-sectional view 52 can be generated by associating a plurality of pieces of element information including the element information 61 of such a geometrical tolerance and forming a multilayer. For example, the point of the reader to be connected is recognized as the connection point from the element information 61 of the geometrical tolerance, and is associated with the shape line (cross-sectional view) at the end of the connection line, and is associated with the datum symbol having the same value.

  In the first control, the image data and the CAD data converted to the element information, which are the same as the appearance at the time of printing, are input, and the coordinate value (coordinate position) is associated with the key, so that the element is Inspection data is generated so that the information is superimposed and recognized by the user. The inspection data is data holding element information such as a sectional view and a geometrical tolerance / datum symbol necessary for the inspection.

  With reference to FIG. 7 as well, an example of generation of inspection data will be described. In the inspection data 70 illustrated in FIG. 7, element information 61 indicating the geometrical tolerance 72 is associated with the image data 71 so that the geometrical tolerance 72 (the same as the geometrical tolerance 50) can be displayed on the image data 71. The linking can be performed by associating the coordinate value of the element information 61 (coordinate x in this example) with the corresponding coordinate value of the image data 71 (coordinate x in this example). Thereby, the inspection data 70 can be displayed in a state where the geometrical tolerance 72 is superimposed on the image data 71. In this example, for the sake of simplicity, an example is given in which only the geometrical tolerance 72 is linked to the image data 71, but the same applies to the elements indicated by other element information.

  In the second control, it is possible to display two inspection data so that they can be compared. This display example will be described with reference to FIGS. FIG. 8 is a diagram showing an example of the inspection data before and after the change of the drawing. FIG. 9 is a conceptual diagram showing an example of the comparison work in the inspection process of FIG.

  The inspection data 80 shown in FIG. 8 includes information 82 indicating a sectional view 81. It is assumed that the CAD data of the drawing on which the check data 80 is based is corrected by the user, and the check data 83 is generated from the corrected CAD data and the image data. The inspection data 83 after the correction includes information 85 indicating a cross-sectional view 84 in which the cross-sectional view 81 has been moved. Even when the cross-sectional view 81 is moved to the cross-sectional view 84 (when the coordinate values are changed) as described above, since there is no change in the shape line or the dimension line, a value other than the coordinate values is used as the primary key. The check data 80 before the change and the check data 83 after the change (correction) can be linked.

  Thereby, it is possible to display the inspection data 90 of the new drawing and the inspection data 91 of the old drawing, and to display the sectional view 92 of the element selected from the new drawing or the old drawing by the user operation. it can. In the cross-sectional view 92, by displaying the new drawing and the old drawing in different colors, the user can confirm the changing point in the cross-sectional view 92. This display example corresponds to the display example in step S14 of FIG.

  Next, display examples in steps S15 and S16 in FIG. 4 will be described with reference to FIGS. FIG. 10 is a conceptual diagram showing an example of the compatibility checking work in the check process of FIG. 4, and FIG. 11 is a conceptual diagram showing an example of an overlap check in the check process of FIG.

  A display example in step S15 will be described. When displaying the element information of the inspection data, for example, a line L connecting the same datum symbol may be displayed as in a cross-sectional view 100 of FIG. This allows the user to confirm the relationship between the geometrical tolerance and the datum. Not limited to the line L, various display forms can be adopted to confirm the compatibility between the element and the drawing rule.

  A display example in step S16 will be described. When displaying the entire drawing such as an entire view or a cross-sectional view of inspection data, the image data (data indicating the appearance) is included as well as the image data as shown in the drawing 110 of FIG. Configuration information (lines, values, etc.) may be displayed. This allows the user to confirm the degree of overlap of each element in the drawing, such as the overlap D between the shape line and the dimension value.

  As described above, the check checking support apparatus 1 is a system that utilizes image data such as image data at the time of printing (image data indicating the same state as when a person views a drawing) and CAD data. is there.

  In the inspection work illustrated in steps S14 to S16 in FIG. 4, it is important to judge by the element constituting the drawing or the appearance at the time of printing, and it is possible to inspect drawings created by different CAD systems. is necessary. For this reason, the check-checking support apparatus 1 is an apparatus that utilizes not both the image data having the appearance information and the CAD data having the element information in the drawing independently but in a combined manner. . In particular, the check plan support device 1 links the image data with the CAD data using the coordinate values of the values, lines, attributes, and the like of the CAD data as primary keys, and uses the two as the data for check. The user is prompted to check using the data for checking separately generated from. This allows the user to carry out these check operations with high accuracy without causing information shortage.

  In order to generate inspection data that enables efficient inspection, it is necessary to recognize elements in the drawing. However, in the inspection support device 1, the configuration information of the CAD data is linked to each other as element information. Also, association and layering of element information are performed.

  In the inspection check support apparatus 1, the hierarchical appearance, the element information, and the configuration information can be confirmed by the inspection data from the overall appearance drawing by such association and layering. It is also possible to check a drawing desired by the user, such as a cross-sectional view, only by the appearance shape. Due to the former effect, the user can be accurately inspected to confirm the compatibility between the element and the drawing rule.

  Further, in the inspection support apparatus 1, since the elements in the drawing to be compared are sequentially associated from the upper hierarchy by such association and layering, it is possible to perform association using a primary key other than coordinate values. The element whose position has moved can also be accurately associated.

  As described above, in the inspection check support apparatus 1 according to the present embodiment, the inspection check data before and after the change is displayed in association with a value other than the coordinate value in the element information as the primary key. Therefore, according to the inspection support apparatus 1 according to the present embodiment, even when the position of the element is greatly changed when the CAD data is changed, the elements to be compared are associated with each other. The CAD data can be checked by a user (checking operator).

(Alternative example)
Next, an alternative example in the present embodiment will be described.
The inspection check support device according to the above-described embodiment is not limited to the one illustrated in FIG. 1, but may have any function. For example, it may be configured as a distributed system. The CAD data may have a different data structure or definition depending on the system that generates the CAD data. However, terms such as configuration information and element information can be applied to corresponding terms in each system.

Although the present embodiment has been described above, the above embodiment has the following features.
That is, the inspection support apparatus 1 according to the embodiment includes the display unit 12 and the control unit 10. The control unit 10 executes the first control and the second control. The first control associates coordinate values of the plurality of pieces of configuration information with respect to a plurality of pieces of configuration information included in CAD data according to a predetermined rule, and converts the plurality of pieces of configuration information as element information having coordinate values. A grouping process for grouping is executed according to a plurality of types of rules. The first control is to link the data of the area corresponding to the element information in the image data obtained by imaging the CAD data to each element information of the CAD data, using the coordinate value in the element information as a primary key, Generate In the second control, two inspection data generated by the first control for the two CAD data to be compared are linked for each element information with a value other than the coordinate value in the element information as a primary key. In the state shown in FIG.

  In the inspection support apparatus 1 having the above configuration, even when the position of an element is greatly changed when the CAD data is changed, the CAD data is provided to the user in a state where the elements to be compared are associated with each other. You can check the map.
