Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and an apparatus for controlling display of modeling data of a product model such as STEP (Standard for the Exchange model data).
[0002]
STEP is a standard relating to description and exchange of product data (product data), and standardization is currently being promoted by the International Organization for Standardization (ISO). This standard is for expressing and exchanging necessary data for a product throughout its life cycle, such as conceptual design, detailed design, prototyping, test, production, or support. CAD data, NC data, etc. , For any kind of data.
[0003]
Modeling data created based on such a standard is often difficult to understand for anyone other than the creator when the data is displayed as it is. Moreover, since the standard itself has a huge amount, it is not easy to understand the standard and to interpret modeling data created by others. Therefore, a display control method that can help understanding of these modeling data is desired.
[0004]
[Prior art]
At present, various other data such as drawing data and data on configuration information of products and parts handled in each industry are generally managed by a database. For example, a database is constructed using drawing data such as CAD, and NC data is created based on the drawing data. These data are exchanged between the design department and the manufacturing department.
[0005]
In order to build a database, there are specialists who create modeling data at each site (company), and how to build data such as CAD into the database is, for example, the data structure. The specifications are different at each site.
[0006]
In other words, in the data structure of modeling data in which a plurality of elements are linked to each other, the name of each node (element) is freely assigned by the creator, so that the created modeling data can be understood by anyone other than the creator. Often cannot.
[0007]
For example, in the modeling data MD8 shown in FIG. 9, the tree TR1 is configured by connecting elements YS1 to YS6 of six layers by links LK1 to LK5. The content of the data of the element YS1 of the first layer is “keyboard”. The element YS2-1 of the second layer is "data to be arranged", the element YS2-2 is "shape", the elements YS3-1, 2-2, and 3 of the third layer are "keyboard type", and the element YS4- of the fourth layer. 1, 2, 3 are "data to be arranged", the element YS5-1 of the fifth layer is "A", "I", "U" ..., the element YS5-2 is "A", "B", "C" ... .. Are the data of the next link destination.
[0008]
According to the modeling data MD8, even if the content of the data is displayed as it is, a person other than the creator can easily understand the content.
[0009]
[Problems to be solved by the invention]
However, for example, if the content of the data in the element YS2-1 is not "data to be arranged" but "ABC" or the like, it becomes difficult for anyone other than the creator to easily understand. In such a case, it is necessary to sequentially follow the entire tree TR1 or another tree TR, and the work is troublesome. This is because, if the data content of the element YS does not correctly represent the meaning of the element YS, the content of a certain element YS can be known only by following the order of the element YS. In the case of the element YS linked to the end, it is necessary to follow in order from the beginning, and in the case of the element YS linked to the beginning, look at the contents of the element YS linked thereafter. There is a need.
[0010]
If the modeling data MD8 is based on a standard, it is impossible to understand what the data means unless the standard and the data structure of the tree TR1 are traced.
[0011]
Further, in the above-described tree TR1, the element YS3-1 of the third layer is described as “keyboard type”, and by looking at this expression, the element YS5-1 linked to the lower level is a Japanese keyboard. Cannot be immediately understood. Further, there is also a case where there is no description of "keyboard type" and only a blank frame is displayed. In these cases, it is only after seeing "a", "i", "u" ... of the element YS5-1 of the fifth layer that it is understood that it is a Japanese keyboard.
[0012]
The element YS5-1 of the fifth layer is described as a character string such as "A", "I", "U", and so on. Therefore, in this case, the contents of the data can be immediately understood. , May be described in a data type other than a character string. For example, there is a case where the position is described by coordinates at which each character string is arranged, a code of each character string, or the like. In these cases, if the content described as in the prior art is expressed as it is, it is necessary to look at the definition document one by one in order to know the content, and it is difficult to understand the content of the tree TR1.
[0013]
Normally, when modeling data is created, it is necessary to verify whether or not the contents of the data are correct. However, conventionally, the work for the verification has been extremely difficult.
[0014]
The present invention has been made in view of the above-described problems, and provides a method and an apparatus for controlling the display of modeling data that can be easily understood even by a person other than the creator of the modeling data. Aim.

[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a block diagram functionally showing a display control device 1 according to the present invention, FIG. 2 is a diagram showing an example of a list LT1, and FIG. 3 is a diagram showing an example of conversion tables TB1 and TB2.
[0023]
In FIG. 1, the display control device 1 includes an AP structure definition dictionary 11, a diagram structure definition dictionary 12, a database 13, an AP modeling data file 14, a diagram modeling data file 15, a pattern file 16, a template model file 17, and a diagram model file 18. , Model generation units 21 and 22, instance analysis unit 23, diagram data mapping unit 24, entity list display unit 25, instance structure display update unit 26, attribute detailed information display unit 27, template creation unit 28, and the like.
[0024]
The AP structure definition dictionary 11 and the diagram structure definition dictionary 12 are dictionaries that define the data structure of the modeling data. The AP structure definition dictionary 11 is provided with a list LT1 and conversion tables TB1 and TB2 described later. The diagram structure definition dictionary 12 is provided with a diagram schema that defines a diagram corresponding to the EXPRESS data type.
[0025]
Many modeling data MD are registered in the database 13. The structure of the modeling data MD in the database 13 is analyzed by the instance analysis unit 23, and the created instance configuration pattern is stored in the pattern file 16. An AP model is generated by the model generation unit 21 using the instance configuration pattern and the APAIM schema of the AP structure definition dictionary 11 as an input, and registered in the AP modeling data file 14. The model generation unit 21 uses, for example, an SDAI (Standard Data Access Interface) model generation command or the like for STEP modeling data. In addition, a schema model of the schema structure definition dictionary 12 is input, and a model model is generated by the model generation unit 22. The model generation unit 22 uses, for example, an SDAI model generation command. The schematic model includes, for example, a display pattern or a type of an outer frame. The generated schematic model is stored in the schematic modeling data file 15.
[0026]
The graphic data mapping unit 24 sequentially follows the contents of the modeling data MD extracted from the database 13, determines the contents of each element (instance), and converts the contents into an appropriate expression for graphic display. In that case, the table LT1 or the conversion tables TB1, TB2 of the AP structure definition dictionary 11 are referred to as needed. That is, for example, for a specified element in the modeling data MD, the data type of the element is determined. If the data type is a character string STR, the character string STR is used as the content of the data. Is not a character string STR, the data is converted to a character string STR with reference to the conversion tables TB1 and TB2.
[0027]
Note that there are three types of data: a character string STR, coordinates CDN, and code COD. The character string STR is one in which the content to be expressed is directly described by character string data surrounded by a single quote mark or the like. The coordinate CDN indicates the position of a character string by coordinates. For example, the coordinates X and Y where the character string is arranged are described in parentheses, such as (40, 50). is there. The code COD indicates a character string by a code, and is described by a code number indicated in the standard and "#" preceding the code number, for example, # 10000.
[0028]
As shown in FIG. 3A, the conversion table TB1 associates the coordinates CDN with the character strings STR. For example, the coordinates “(40, 50)” are “A” in the character string STR, and the coordinates (80, 50) are “I” in the character string STR.
[0029]
As shown in FIG. 3B, the conversion table TB2 associates codes COD with character strings STR. For example, the code “# 10000” is “A” in the character string STR, and the code “# 10001” is “I” in the character string STR.
[0030]
If the data type is not the character string STR, the graphic data mapping unit 24 detects the first part of the data, determines the data type, and obtains the character string STR by referring to the conversion tables TB1 and TB2.
[0031]
In addition, the schematic data mapping unit 24 selects and determines a display frame of various shapes such as a circle or a rectangle with reference to the type stored in the template model file 17. In this way, data to be graphically displayed is obtained corresponding to the modeling data stored in the database 13. Based on the obtained data, the data is graphically displayed on the display surface HG of the display device, or is printed and displayed on paper or the like.
[0032]
The entity list display unit 25 performs control for displaying a list of entity patterns and the number of elements corresponding to each pattern on the display surface HG based on the associated information. Information selected from the list display by the entity list display unit 25 is passed to the instance structure display update unit 26, and the element is divided and displayed for each data structure pattern. The display target includes the inheritance relationship and the reference relationship of the elements. When the reference relationship portion is selected, the destination is further developed for each pattern. The expanded data is reflected in the entity list display unit 25 as the number of unused elements. The data structure of the selected and expanded structure is stored in the template model file 17 by the template creating unit 28 by the “integration (grouping) function”. The attribute detailed information display unit 27 operates an attribute list on the selection screen of the instance structure display update unit 26, and displays the detailed data.
[0033]
Next, a specific example in which the display control device 1 graphically displays the modeling data MD8 shown in FIG. 9 will be described.
In the element YS3-1 shown in FIG. 9, "keyboard type" is described. When the element YS3-1 is graphically displayed on the display surface HG, the keyboard is referred to as "Japanese keyboard", "English keyboard", or "Chinese keyboard" by referring to the list LT1 shown in FIG. It is recognized that there are three types. Then, by analyzing the first character string "A" of the element YS5-1 following the element YS3-1, it is determined that the character string is Japanese. Therefore, in the graphic display of the element YS3-1, as shown in FIG. 3, "Japanese keyboard" is displayed in a rectangular frame as in the graphic RYS3-1 on the display surface HG1.
[0034]
In addition, “A” is described in the element YS5-1, and when this is graphically displayed on the display surface HG1, “A” is displayed in a rectangular frame, as in the diagram RYS5-1 shown in FIG. .
[0035]
If “(40, 50)” is described in the element YS5-1, the graphic data mapping unit 24 determines that the type of the data is the coordinate CDN when graphically displaying this. The character string STR of "a" is converted by referring to the conversion table TB1. Therefore, the image is displayed on the display surface like the pattern RYS5-1 shown in FIG.
[0036]
Further, when “# 10000” is described in the element YS5-1, when this is graphically displayed, it is determined that the type of the data is the code COD, and by referring to the conversion table TB2, To a character string STR. Therefore, the image is displayed on the display surface like the pattern RYS5-1 similarly to the above.
[0037]
FIG. 5 and FIG. 6 are diagrams showing another example when the elements are graphically displayed.
FIG. 5 shows the display surface HG2 when the element YS5-1 is designated and displayed graphically. On the display surface HG2, in addition to the contents of the data of the element YS5-1, the schematics RYS3-1 and RYS1 of the data of the two elements YS3-1 and YS1 linked to the higher level and the lower level of the element YS5-1 Is simultaneously displayed with the symbol RYS6-1 of the element YS6-1 linked to. Further, the number QT1 of the same elements as the specified element YS5-1 in the modeling data MD8 is simultaneously displayed in the lower part of the rectangular frame. In the case of this example, it can be seen that there is only one character string STR of "a" in the Japanese keyboard.
[0038]
According to the display surface HG2, the history up to the specified element YS5-1 is obvious. Further, since the number QT1 is displayed, it is useful for determining whether or not the data of the modeling data MD8 is accurate. In the case of the above example, if the number QT1 is two, it is understood that the data is not accurate.
[0039]
Further, when the displayed graphic RYS6-1 is clicked on the display surface HG2 shown in FIG. 5 with a mouse (not shown), the part is further expanded and graphically displayed as shown in FIG. 6, for example.
[0040]
In FIG. 6, data on the shape of the keyboard, which is a tree TR different from the tree TR1 of the modeling data MD8, is displayed as diagrams RY1, RY2, and RY3. The element linked below is displayed as a diagram RY4, and the number QT2 is also displayed.
[0041]
Next, a control method of the graphic display in the display control device 1 will be described with reference to flowcharts shown in FIGS.
In FIG. 7, with respect to a specified element in the modeling data MD, the contents of data of another element linked below the specified element are determined (# 11). The validity of the selected expression is determined with reference to the AP structure definition dictionary 11 (# 12), and if it is valid, a graphical representation thereof is performed (# 13). If it is not appropriate, for example, if it is not described in the AP structure definition dictionary 11, an error is displayed.
[0042]
In FIG. 8, the type of the designated element in the modeling data MD is determined (# 21). The character string STR is converted into a character string STR with reference to the AP structure definition dictionary 11 (# 22), and the converted character string STR is represented graphically as the contents of the data (# 23).
[0043]
In this manner, by graphically displaying the modeling data MD8 by the display control device 1, the contents can be easily understood even by a person other than the creator of the modeling data MD8.
[0044]
In other words, when the modeling data of STEP is displayed as it is, it is necessary to follow the text with text. Anyone who does not know the know-how can easily understand it in a short time.
[0045]
In the above embodiment, the configuration of the entire display control device 1 or each unit, the processing content, the processing order, and the like can be appropriately changed in accordance with the gist of the present invention. The display control device 1 can be realized by combining a personal computer, another computer, or an appropriate hardware circuit.
[0046]
【The invention's effect】
According to the present invention, the contents can be easily understood even by a person other than the creator of the modeling data without knowing the standards or know-how for interpreting the standards.
[0047]
Therefore, for example, when verifying whether or not the content of the created modeling data is correct, the time and labor required for the work are greatly reduced.
