DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CAD (Computer Aided Design) which supports calculations by an electronic computer.
Attribute data editing function that improves reliability, operability, productivity, maintainability, etc., and ensures resource reuse, especially by changing the shape of the figure and attribute data collectively in the system With parametric design system.

[0002]

2. Description of the Related Art Conventionally, in a manual design, when a bill of materials is added to a large number of drawings constituting a product and is created, the bill is based on the bill of materials of the products and parts described in the drawings. , Had to manually create the bill of materials. Although this problem did not basically change even if the efficiency of drawing creation work by the CAD system was improved, Japanese Patent Laid-Open No. 63-21 / 1988
In the Japanese Patent Publication No. 9075, a tentative solution has been found by the proposed automatic parts table creation processing method.

[0003] On the other hand, when the number of drawings to be created increases, an increase in the number of man-hours for managing the drawing becomes a problem. In particular, if individual drawings are created only for parts whose dimensions are only partially changed, such management becomes difficult. It gets even harder. In view of this, Japanese Patent Application Laid-Open No. H4-5766 proposes a method for increasing the efficiency of the number of drawings by using a parametric function for such components as one drawing. Japanese Patent Application Laid-Open No. 02-186481 proposes a process of transferring data (attribute data) attached to a component to be arranged to a drawing in the arrangement of a parametric component.

[0004] However, when a component bill of parts arranged in a drawing is created by a parts bill creation process in a drawing in which parametric parts are arranged, if there are a plurality of identical parts that differ only in parameter values, attribute data is placed after arrangement. You cannot identify them unless you change them. In addition, it is necessary to change attribute data (weight, etc.) whose value should be changed due to parametric deformation at any time after arrangement, but this is inefficient in work,
Further, there is a possibility that the correction is omitted.

When a dimension element to be parametricized and a dimension change condition thereof and a graphic element related thereto are designated in an existing CAD drawing (original drawing), a related graphic element is designated and input based on the original drawing. Then, based on the original drawing, the coordinate values of related graphic elements are changed, and a drawing similar to the original drawing (similar drawing) can be created.
Japanese Patent Application Laid-Open No. Hei 0-199367) and a housing CAD system capable of responding to addition of members or change of member information by generating members as parametric parts (Japanese Patent Application Laid-Open No.
No. 3-9480), a parts data search unit and an intermediate file creation unit search a database to read parts table item data to be changed and instruction data relating to the changes, and read the part list item data of the read parts table item data. There has been proposed a drawing creating apparatus (Japanese Patent Application Laid-Open No. 08-15360) for extracting parts table item data according to instruction data read from the inside and adding it to a basic drawing to create a completed drawing.

[0006]

However, in the above-mentioned prior art, each of the above-described techniques is performed based on a created figure for a part and the attribute of the part. However, the shape of the same parametric part is changed by a parametric editing function. Also, a drawing in which a plurality of identical parametric parts having only different parameter values are arranged because attribute values to be referred to for identifying the parts table and attribute values to be changed with parametric deformation are not changed. When a parts list is created for these parts, these parts cannot be identified as different parts. Further, the attribute that needs to be changed is not changed with the parametric deformation.

Further, the change of the attribute data must be performed while watching the parameter values specified in the parametric editing process, and the increase in the work amount due to the increase in the number of arranged parts is inevitable. Since there is a possibility that an omission of correction or an erroneous correction may occur due to the increase, there is a problem that a part with a parametric figure is not correctly created.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. In a drawing in which parametric parts having different parameter values are arranged, it becomes possible to identify these parts in creating a parts table. An object of the present invention is to provide a parametric design system with an attribute data editing function in which the number of steps involved in inputting a large number of parameters performed in a parametric editing process is reduced and the possibility of input error is reduced.

A parametric editing processing means for updating a graphic or attribute data, and a parameter table in which a combination of a plurality of parameters in the first and second parametric data is associated with each parameter as a standard are defined. A parameter table defining means, wherein the parametric editing processing means is arranged in the drawing. Parameter setting processing means for performing a parameter setting process based on the first and second parametric data of the parametric component obtained, and, when the parameter table has data, one of the parameters in the parameter table. Parameter batch setting processing means for setting standards and collectively setting values for parameters in the parameter table; graphic updating processing means for updating graphic data after setting values of all parameters in the parameter table; And an attribute data update processing means for updating attribute data after setting values of all parameters in the parameter table.

After arranging the necessary parts, the part list addition / update processing means reflects the parts on the parts table data.

Therefore, according to the present invention, it is possible to change only a figure, change only an attribute, and change both a figure and an attribute by changing a parameter. Even in a drawing in which parametric parts having different parameter values are arranged, the parts can be changed. Parts can be identified in table creation, and the number of steps involved in inputting a large number of parameters performed in the parametric editing process can be reduced, and the possibility of input errors can be reduced.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a parametric design system with an attribute data editing function according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the first embodiment according to the present invention. In FIG. 1, component data 2 is data for creating data of components to be arranged in FIG.

The component data 2 includes graphic data 31, parametric data 32, attribute data 33, and a parameter table 34. The graphic data 31 is data for displaying a graphic on the visual device 3 as a display means, and is drawn by the drawing processing means 11. The attribute data 33 is data attached to a figure or a part.
The parametric data 32 includes "parameters related to the graphic data 31 or the attribute data 33" and "operations associated with the change of parameter values", that is, "deformation method or attribute data 33 of the graphic data 31 accompanying the change of parameter values". And "change method of".
Further, when the parameter table 34 is required, the parameter table definition processing means 14 stores the combination data of the parameter name and the parameter value in the parameter table 34.

The parametric definition processing 12 includes a parametric data 32 (first parametric data 32) representing as information the “parameter associated with the graphic data 31” and the “method of transforming the graphic data 31 in response to a change in the value of the parameter”. ) Is performed. The attribute data definition processing means 13 performs a process of defining the attribute data 33 and “parameters related to the attribute data 33”.
Parametric data 3 representing, as information, a “method of changing attribute data 33 in response to a change in the value of the parameter”
2 (second parametric data). The graphic data 31, parametric data 32 and attribute data 33 are stored in the drawing database 36 by the component storage processing means 15.

Next, a portion for creating the drawing data 1 will be described. The drawing data 1 includes graphic data 40, parts table data 35, and parts data 37 to 39. The graphic data 40 is synonymous with the graphic data 31 described above. The parts table data 35 is data including attribute data of the parts arranged on the drawing. The part data 38 and 39 are drawing data without a parameter (no parametric) related to a figure, and the part data 37 is data of a parametric part with a parameter.

When arranging parts on a drawing, the part arrangement processing means 16 selects part data to be arranged from a drawing database 36 and temporarily arranges the selected part data on the drawing 1. When the component data 38 and 39 without parametrics are arranged on the drawing 1, the process ends. The parametric component data 37 (hereinafter referred to as parametric component data) is arranged on the drawing 1 by the component arrangement processing means 16 and then the graphic and attribute data are updated by the parametric editing processing means 17.

Regarding the parts table, the parts table definition processing means 1
In step 9, information on data is defined in the parts table and stored in the parts table data 35. After arranging the component data necessary for the drawing, the component table addition / update processing means 18 reflects the component data on the component table data 35.

FIG. 2 shows the first part of the parametric design system with the attribute data editing function according to the present invention, showing in detail the part of the parametric editing processing means 17 shown in FIG.
FIG. 2 is a block diagram illustrating a configuration of an embodiment. In FIG. 2, the same parts as those in FIG. 1 are denoted by the same reference numerals, to avoid redundant description of the configuration. In FIG. 2, the parametric editing processing means 17 performs parameter setting processing by the parameter setting processing means 21 based on the parametric data 42 of the parametric component data 37 arranged on the drawing. In this case, the value of one parameter in the parameter table 44 is set by the parameter batch setting process 22, and the values are collectively set for the parameters in the table. Other values are set individually as needed.

After setting all the parameters in this way, the graphic data 41 is updated by the graphic update processing means 23, and the attribute data 43 is updated by the attribute data update processing means 24.
Further, the parts table addition / update processing means 18 performs the parts data 3 without parametric out of all the parts arranged in the drawing, that is, the parts data 38 and 39 without parametric and the part data 37 with parametric.
8 and 39 are reflected in the component table data 35 based on the attribute data 45 and 46, respectively, and the parametric component data 37 are reflected in the component table data 35 based on the attribute data 43.

Next, the parametric parts will be described. FIG. 3 is an explanatory view showing an example of the parametric parts. In the example of FIG.
Has a component name and a head diameter as attribute parameters (attribute item names), and the corresponding attribute parameter values (attribute data)
Is "Screw A" for the part name, and the head diameter is set as the value of the parameter R in the parametric editing process. Note that the attribute parameter for setting the attribute parameter value in the parametric editing process, such as the head diameter, is described in the form of “attribute name (parameter)”, such as “head diameter (R)”. On the other hand, there is “R” as a graphic parameter, which is linked to the head diameter (R). Also, since the number of parameters set in the parametric component 51 is small, no parameter table is set for this component.

FIG. 4 shows components 52,
It is a top view showing the example which has arranged 53 and parametric parts 51. FIG. 5 is a component diagram of a parametric component. In the parametric component 71, a component name, a standard S, a head diameter R, a diameter M, a length L, and a weight W (in FIG. 5, The standard S and the weight W are not shown), and corresponding parameter values include:
There is “screw B” for the part name, and other parameters are set by the parametric editing means 17.

The figure parameters include a head diameter R,
And a diameter M, a length L, and a rotation angle Θ. As shown in FIG. 7, a parameter table is set in the parametric component 71, and a standard S, a head diameter R, a diameter M, a length L, and a weight W are defined as parameters.
The parameter table has a column 72 representing such parameters and columns 73 to 78 which are combinations of the set values. FIG. 6 shows parts 81, 82,
It is a top view showing the state where 83 and the parametric component 71 were arranged.

Next, the operation of the first embodiment will be described with reference to a parametric part 51 shown in FIG.
A description will be given by taking as an example a component in which the components 52 and 53 without parametric shown in FIG. 6 and the component 81 without parametric shown in FIG. First, creation of a part drawing will be described.
The drawing processing means 11 performs a process of drawing a circle, a line, and the like, and includes a figure such as the parametric part 51 shown in FIG. This drawing processing means 1
1, the graphic data 31 is created. The graphic data 31 can be represented, for example, as in the following [Table 1].

[0024]

[Table 1]

The example of [Table 1] is represented by a model for easy understanding of data to be managed internally, and is different from actual data. In this [Table 1], the graphic numbers are changed from "1" to "13", and the data of the graphic number "1" is "a circle having a radius of 30 whose center coordinates are (100, 100)". The data of the graphic number “13” is “the starting point is (115, 10
5), and the end point is a line of (110, 95).

The parametric definition processing means 12
Defines a parameter for determining the shape of a certain figure, etc., and the parametric definition processing means 12 includes a parametric data 32 for determining a deformation method of the figure data 31.
Is defined. As an example of the parametric data 32, as shown in the following [Table 2], for example, it is data relating to parameters that determine (or change) the shape of a certain figure, and is applied to the parametric part 51 in FIG. In other words, the parameter is “R”, the parameter value is “30”, and the meaning is “parameter radius of the graphic (circle) of graphic number 1”.

[0027]

[Table 2]

Next, the attribute data definition processing means 13
Set the item name and data for a certain part. The attribute data 33 is defined by the attribute data definition processing means 13, and its parameters are stored as parametric data 32. The attribute data 33 is, for example, data characterizing a drawing or a part as shown in the following [Table 3]. Conventionally, even if a figure is deformed, the data does not change.

[0029]

[Table 3]

In [Table 3], "part name", "head diameter", and "weight" are listed as "attribute item names". In the example of FIG. No,
It is added to [Table 3] as it is linked to the deformation of a figure not related to the figure data. In the first embodiment,
As described above, the attribute data which has been fixed with respect to the change of the figure in the past is to be changed in synchronization with the deformation of the figure. Therefore, the component name does not interlock with the figure editing, and can be said to be merely conventional attribute data.

The attribute parametric data is
As an example, it can be represented as in the following [Table 4].

[0032]

[Table 4]

In this [Table 4], the parameter "R" is
Parameter value "30", meaning "attribute representing head diameter"
And the parameter “W” has a parameter value of “210”.
Indicates that the meaning is “attribute representing weight”.

The parameter table definition processing means 1
No. 4 defines a table in which a combination of a plurality of parameters is represented by one parameter. In FIG. 7, a plurality of parameters M, L, and W are represented by parameters called “standards”.
For example, if the standard M3 is specified, R = 6.0, M =
3.0, L = 8.0, W = 14.0 are designated. (The difference from the prior art is that the conventional weight W is not data relating to a figure, so the conventional weight W is not a parameter. In the first embodiment, the weight W is also a parameter). If the parameter table 34 is required,
The combination of the parameter name and the parameter value is stored in the parameter table 34 by the parameter table definition processing means 14.

Graphic data 31, parametric data 3
2. The attribute data 33 is stored in the drawing database 36 by the component storage processing means 15. When the graphic data 31, parametric data 32, and attribute data 33 are stored in the drawing database 36 by the component storage processing means 15, a name (component name) is given. For example,
As shown in FIG. 3, the part name is stored as “screw A”.

Next, the operation of selecting the parts stored in the drawing database 36 and arranging them in the drawing to create the drawing data 1 will be described. When arranging a part in a drawing, first, data of a part selected by designating a part name from a drawing database 36 by the part arrangement processing means 16,
That is, a design drawing of a part is taken out and arranged in the drawing.
At this time, the component arrangement processing means 16 stores the drawing database 3
Among the parts taken out from No. 6, graphic data and attribute data are arranged as part data for the part 52 without the parametric {part name (part A)} and part 53 {part name (part B)}, and the processing ends. I do.

On the other hand, if the component specified by the component placement processing means 16 from the drawing database 36 is a parametric component 51, the component placement processing means 16 converts the component data (graphic data, parametric data, attribute data). Placed in the drawing. Next, the value of the head diameter R is input by the parameter setting processing unit 21 in the parametric editing processing unit 17. Here, "4" is input as this value. Hereinafter, similarly, FIG. 4 is a drawing in which the parts having the values of the head diameter R of “4” and “2.5” are arranged, and FIG. 4 shows a parts table of the drawing name (product A). 61, components 54 to 57 having a head diameter R of “4”, components 58 having a head diameter R of “2.5”,
59 and 59 are shown.

In FIG. 4, as described above, the component 5
After arranging 2-57, the parts list update / addition processing means 18
Thereby, the parts table 61 is arranged in the drawing. The parts table update addition processing means 18 performs processing of adding and updating the number of parts in the actual drawing to the parts table 61 based on the data of the parts arranged in the drawing by the parts arrangement processing means 16. That is, additional updating is performed as shown in the parts table 61 of FIG. In the parts table 61 shown in FIG.
2 parts B each with screw A and head diameter 2.5
The figure shows a case where four pieces having four head diameters are arranged. These are updated by the parts list update / addition processing unit 18.
The parts are identified by the combination of the part name and the head diameter.

Conventionally, when performing the component addition / update process by the component table update / addition processing means 18, if the component addition / update process is directly performed after the components are arranged in the drawing, the following table 5 is obtained.

[0040]

[Table 5]

[Table 5] and the parts table 6 in FIG.
As is clear from comparison with No. 1, in Table 5, the screw A
No distinction is made between head diameters “4” and “2.5” and the quantity is not classified. The only solution to this problem is to perform one of the following items (1) and (2). (1). After the parts are placed, set the attribute item "head diameter" of screw A to 1
Change one by one. (2). At the time of component creation, a parametric update process is performed in advance, and components whose head diameters R are "2.5" and "4.0" are separately stored in the drawing database. For example, the head diameter of the screw A is stored as “2.5” and the head diameter of the screw A is stored as “4”.

Here, when the description is returned to the state where the parts table 61 is arranged in the drawing as shown in FIG. 4 by the parts table update / addition processing means 18, as shown in FIG. When 61 is arranged, rows 62,
63 corresponds to the parts 52 and 53, respectively. Also,
The row 64 corresponds to the components 54 to 57, and the row 65 corresponds to the components 58 and 59, and the same parametric component is identified by a difference in parameter value.

Next, the operation of the first embodiment using the parameter table will be described with reference to FIGS. 5, 6, and 7. First, components 81 (component C), 82 (component D) and 83 (component E) without parametric shown in FIG. Further, for the parametric component 71 shown in FIG. 5, component data is arranged on the drawing by the component arrangement processing means 16. Since the component 71 has the parameter table shown in FIG. 7, the parameter table is also arranged.

Thereafter, the parametric editing processing means 17
In the parameter setting process 21 in the middle, “M5A” is selected as the value of the standard S from the parameter table of FIG. By this selection, the value R = 1 in the column 74 of each parameter
0.0, M = 5.0, L = 12.0, and W = 40.0 are collectively set. “90” is set for the rotation Θ as a parameter other than the parameter set in the parameter table.

The component arranged as described above is the component 87 shown in FIG. Similarly, the standard M5A is selected from the parameter table of FIG.
0 ”is set. In this way, the parts 86 are arranged as shown in FIG. Further, the standard 73 “M
2 ”and set the rotation angle Θ to“ 90 ”to set the part 8
4, 85 are arranged as shown in FIG. In FIG. 6, when the number of components in the drawing is updated in the parts table by the parts table addition / update processing means 18, the parts table 91 is arranged in the drawing.

In the parts table 91, rows 92, 93, 9
4 corresponds to the parts 81, 82, 83, respectively, the row 95 corresponds to the parts 84, 85, and the row 96 corresponds to the part 8
6, 87 respectively. Further, according to the parameter table of FIG. 7, the weight as the attribute data is different between the rows 95 and 96. Line 95 weighs "12.0"
, But the weight of row 96 is “40”.

Next, a second embodiment of the present invention will be described. FIG. 8 is a block diagram showing the configuration of the second embodiment according to the present invention. In FIG. 8, FIG.
The configuration of the part related to the component data 2 shown in FIG. 2 is the same as that in FIGS. 1 and 2, and the illustration thereof is omitted. In FIG. 8, the same parts as those shown in FIGS.
The same reference numerals are given. FIG. 8 shows only a portion related to the drawing data 1 in FIGS.
The parts data 101 to 103 and the parts selection processing means 104 are different from the parts related to the drawing data 1 in FIGS.

The part data 101,
Reference numerals 102 and 103 denote parts having parametric characteristics.
Here, let us consider a case where the design is changed and the part 103 is deformed in the drawing in which the parts are already arranged in the drawing and the parts table is generated. First, the component selection processing unit 104 converts the component
Select 3. Next, the graphic data and the attribute data of the component 103 are changed according to the parametric editing processing unit 17 and then reflected in the component table data 35 by the component table addition / update processing unit 18.

Next, the operations of the parametric editing process and the parts table addition / update process will be described with reference to FIG.
FIG. 9 is a parts table obtained as a result of performing parametric editing processing and parts table addition / update processing for the parts 87 shown in FIG. First, the component 87 shown in FIG. 6 is selected by the component selection processing unit 104, and the standard S is set to “M” in the parameter table of FIG.
5B ". Thereby, the head diameter R = 10.0, M = 5.0, L = 14.0, and the head diameter in the column 77 in FIG.
W = 50.0 is set collectively. The setting of the rotation angle Θ is not changed.

Next, the graphic is updated by the graphic update processing means 23 shown in FIG. 2, and the attribute data is updated by the attribute data update processing means 24. Thus, the parts table addition / update processing means 18 performs the parts table addition / update processing on the drawing. FIG. 9 shows the result of performing the parts table addition / update processing by the parts table addition / update processing means 18. As is clear when comparing the parts table 91 in FIGS. 9 and 6, the row 96 of the parts table 91 is replaced with the rows 97 and 98 of the parts table in FIG.
It can be seen that the change is reflected in the parts list.

[0051]

As described above, according to the present invention, the change of the attribute data is incorporated into the parametric editing function, so that the graphic data and the attribute data are associated with each other when the parametric part is created. In the parametric editing process at the time of the placement process on the drawing,
It is possible to change the linkage of these data, and accordingly,
Even in a drawing in which parametric parts having different parameter values are arranged, these parts can be identified in creating a parts table.

In the parametric editing process,
It is possible to define a combination of a number of parameter value settings, and to use a parameter table that sets all parameter values in the table with the setting of the value of one parameter, and thus, in the parametric deformation process, The number of steps involved in inputting a large number of parameters to be performed can be reduced, and the possibility of input errors can be reduced.
