Description

[0001]
[Industrial application fields]
The present invention relates to a CAD data integrated management system, and more particularly to a system for integrated management of different types of CAD data.
[0002]
[Prior art]
Such CAD systems include ICAD / SX (hereinafter referred to as “ICAD”), MCX / S (hereinafter referred to as “MCAD”), and the like. There are also CAD data file formats defined for the purpose of CAD data conversion, and representative examples include IGES (Initial Graphics Exchange Specification), DXF (drawing data conversion file), and the like.
[0003]
The CAD data of the above ICAD needs only a small data size. MCAD CAD data has good operability, although the drawing size is limited. The CAD data in the IEGS format can support the data representation of many CAD systems. The CAD data in DXF format has different characteristics for each CAD data, such as being good at data representation of paint elements.
[0004]
Conventionally, in a MCAD system that creates and displays MCAD CAD data, for example, when trying to display other types of CAD data, for example, CAD data formed by a DXF system, the DXF data is converted to MCAD by a conversion program. The data is converted into a format, and the converted MCAD format CAD data is displayed. The MCAD system stores the converted CAD data in the MCAD format for reuse.
[0005]
Conventionally, CAD data created and displayed by a CAD device is generally stored in the format used by the CAD device. When the CAD data is to be stored in another format, It is converted into a desired format and stored.
[0006]
[Problems to be solved by the invention]
In the conventional system, in order to display different types of CAD data, the operator needs to perform a two-step operation of instructing the conversion and then instructing the display, which is troublesome. Further, when instructing the conversion, it is necessary to recognize the format of the CAD data to be converted and select a conversion program.
[0007]
Further, CAD data has a limit value according to each format rule. For this reason, for example, when there are 5000 elements in one drawing in ICAD and only 3000 elements in one drawing are allowed in MCAD, the CAD data of ICAD is converted to MCAD by conversion program. When converted to CAD data, the number of elements overflows, resulting in a conversion error. In this case, the number of elements to be converted by the conversion program is limited, and reconversion must be performed so that CAD data of one ICAD is output as CAD data of two MCADs. There was a problem.
[0008]
Furthermore, conventionally, even when the displayed CAD data is converted into a different format and stored, a two-step operation is required in the same manner as the display operation, which takes time and effort. In addition, it is not determined which data format is optimal for converting the CAD data being displayed and storing it. Since the format conversion is an approximate conversion, data loss is caused by inappropriate conversion. There was a problem of getting bigger.
[0009]
The present invention has been made in view of the above points, and it is possible to perform an optimal conversion with less data loss without requiring an operation for displaying or storing CAD data, and a plurality of CADs having different data formats. An object of the present invention is to provide a CAD data integrated management system for integrating and storing data.
[0010]

[0015]
[Action]
According to the first aspect of the present invention, when the read CAD data is different from the predetermined data format for display, the format is converted and displayed by the first conversion means including the cited drawing. It is not necessary to be aware of the data format, and it is possible to reduce the time and effort of operation, diagnose the characteristics of CAD data, and perform conversion based on the diagnosis result. Conversion can be performed.
[0016]
In the invention described in claim 2 , since the data format of CAD data is stored, it is possible to know what conversion should be performed in the first conversion.
[0017]
In the invention described in claim 3, since the displayed CAD data is stored as it is or after being subjected to format conversion by the second conversion means, the operator needs to be aware of the data format of the CAD data to be saved. There is no need for operation, and by diagnosing the characteristics of the displayed CAD data, it is possible to know which data format is optimal for conversion, and specify a plurality of data formats. As a result, the displayed CAD data can be converted into a plurality of data formats and stored, so that there is no need for operation.
[0019]
【Example】
FIG. 2 shows a block diagram of a first embodiment of the system of the present invention. In the figure, each type of CAD data is stored in the storage unit 10 as the storage means M2. Here, the storage area of the CAD data is divided according to the format. For example, the CAD data 11a is in the MCAD format, the CAD data 11b is in the IGES format, and the CAD data 11c is in the ICAD format. In addition, the storage unit 10 stores CAD data name (file name), CAD data format, drawing name of the citation drawing, citation information such as the arrangement position and rotation angle and scale of the citation drawing as CAD data storage information, and CAD. Each characteristic value is stored in units of CAD data. The above cited drawing refers to displaying CAD data of a different file in a part of its own drawing, and the format of the CAD data may be different between its own drawing and the cited drawing.
[0020]
The CAD data 11a has the same format as that used by the MCAD-type CAD device 14 for display. For example, when the CAD data 11a is displayed, the CAD data 11a read from the storage unit 10 is directly stored in the CAD data of the CAD device 14. The data is supplied to the data display unit 15 and displayed on the CAD data display unit 15.
[0021]
When the CAD data 11b and 11c having a format different from that of the CAD device 14 are read from the storage unit 10 for display, the CAD data diagnosis unit 16b as the first diagnosis means M4 corresponding to the format of each CAD data is displayed. Conversion diagnosis is performed in each of 16c. The diagnosis result is displayed on the CAD device 14. The operator can set the control parameters of the data converters 18b and 18c according to the diagnosis result.
[0022]
The CAD data 11b and 11c are respectively supplied to the data converters 18b and 18c as the first conversion means M3 and converted into the format of the CAD device 14. The converted CAD data 20b and 20c are respectively supplied to the data display unit 15 as the display means M1 of the CAD device 14 and displayed.
[0023]
Next, a display screen in the CAD device 14 will be described. FIG. 3 shows a startup screen. Here, environment setting, data loading, and data saving are selected by buttons 31, 32 and 33, respectively.
When the environment setting is selected, the screen shown in FIG. 4 is displayed. On this environment setting screen, buttons 36 to 39 are a system program of the format MCAD used for display by the CAD device 14 and conversion programs (translators) for converting other formats DXF, IGES, and ICAD to MCAD and vice versa. Select with. By this selection, the environment setting screen for each program indicated by the tip of the arrow is displayed.
[0024]
When data load is selected on the startup screen, the screen shown in FIG. 5 is displayed. On this data load screen, the file names and formats of all the CAD data stored in the storage unit 10 are displayed in the column 40. Each of the columns 41 and 42 displays the format and storage location of the CAD data designated by the cursor, and the file name is displayed in the column 47. By selecting buttons 43 to 45 from this screen, one of conversion diagnosis, control parameter specification, and control parameter setting can be specified. Here, the control parameter specification is to specify a control parameter when executing data conversion, and the control parameter setting is to set a control parameter.
[0025]
When the above button 43 is selected, conversion diagnosis is performed on CAD data designated by the cursor, and the diagnosis result is displayed on the screen shown in FIG. In FIG. 6, the number of each shape element such as a point or a line is displayed for the CAD data to be converted, and the number of each notation element such as a character string or a dimension is displayed. A diagnostic message is displayed by scrolling the display of FIG. This diagnostic message is a guide for setting optimal control parameters.
[0026]
When the button 45 is selected, control parameters are set. The format of this control parameter setting screen differs depending on the format of the conversion source CAD data and the conversion destination CAD data. FIG. 7 shows a control parameter setting screen when converting CAD data in the ICAD format into the MCAD format. In FIG. 7, presence / absence of conversion of graphic elements such as dots, characters / labels, kanji expression type, input CAD data type, ellipse output format, etc. are set by button selection. Specify the number of elements and the number of significant digits of the output numerical value.
[0027]
FIG. 8 shows a flowchart of the display process of the system of the present invention. This process is executed by the CAD device 14, and is started when the file name of the CAD data to be displayed on the data load screen of FIG. 5 is designated and the execution button 46 is selected.
[0028]
In FIG. 8, in step S <b> 10, storage information of designated CAD data is read from the storage unit 10. Next, it is determined whether or not the CAD data designated in step S12 is the same as the CAD format of the CAD device 14 itself. If the CAD data is the same, the process proceeds to step S14, and if not, the process proceeds to step S16.
[0029]
In step S16, since the designated CAD data is different from the CAD format of the CAD device itself, it is determined whether or not conversion diagnosis is designated by selecting the button 43. When conversion diagnosis is performed here, the process proceeds to step S18, and conversion diagnosis is performed in the corresponding CAD data diagnosis unit. As a result, if necessary, control parameters are set on the control parameter setting screen, and the process proceeds to step S20. If no conversion diagnosis is performed (NO in step S16), the process proceeds to step S20. In step S20, the CAD data designated using the data conversion program of the corresponding data conversion unit is converted into the format of the CAD device itself, and then the process proceeds to step S14.
[0030]
In step S14, it is determined from the storage information of the designated CAD data whether or not there is a cited drawing in the designated CAD data, and if there is, the process proceeds to step S22. In step S22, information such as the data name, arrangement position, rotation angle, and scale of the cited drawing is passed to the data reading function of the CAD device 14, and the process proceeds to step S24. If there is no cited drawing in step S14, the process proceeds to step S24.
[0031]
In step S24, the CAD data designated by the CAD data display unit 15 of the CAD device 14 or the CAD data obtained by converting the CAD data is displayed. Thereafter, it is determined in the same manner as in step S14 whether or not the CAD data displayed in step S26 has a cited drawing. If there is no cited drawing, the process ends. If there is a cited drawing, the process proceeds to step S10, and steps S10 to S26 are repeated for the cited drawing given in the previous step S22.
[0032]
When the operator designates CAD data of a drawing to be displayed, the processing of FIG. 8 is executed, so that even when CAD data having a format different from that of the CAD device 14 is designated, the CAD data is stored as information. Since the CAD format is provided, format conversion is automatically performed in step S20 and displayed in step S24. That is, the operator automatically performs format conversion and display only by specifying CAD data.
[0033]
Further, if the conversion diagnosis is selected on the data load screen, a diagnosis message is output, and by setting a control parameter in accordance with the diagnosis message, the occurrence of a conversion error can be prevented. In other words, it is possible to prevent the conversion from being wasted due to the occurrence of a conversion error although the format conversion is attempted.
[0034]
Further, for example, when DXF format CAD data having an ICAD format citation screen is to be displayed on an MCAD format CAD device, conventionally, the citation drawing is first converted to the MCAD format and then the DXF format CAD data. Is converted to the MCAD format, then the CAD data converted to the MCAD format is displayed on the CAD data device, and then the citation drawing converted to the MCAD format is displayed superimposed on the CAD device. The operator had to give instructions sequentially. In contrast, in this embodiment, when the operator designates CAD data, even if there is a cited drawing in the designated CAD data, the CAD data with the cited drawings superimposed is automatically displayed by repeatedly executing steps S10 to S26. Therefore, the operator's hand is not bothered.
[0035]
FIG. 9 shows a block diagram of a second embodiment of the system of the present invention. In the figure, the same components as those in FIG. In FIG. 9, CAD data 60 in the MCAD format created by the CAD device 14 is stored in 10 by the CAD data storage unit 65. At this time, the CAD data diagnosis unit 66 as the second diagnosis means M6 performs conversion diagnosis when converting the CAD data 60 of the MCAD format into CAD data of a different format, that is, IGES format, DXF format or the like. The diagnosis result is displayed on the CAD device 14, the optimum data conversion unit can be selected according to the diagnosis result, and the control parameters of the data conversion units 68b and 68c as the second conversion means M5 can be set. .
[0036]
The CAD data 60 is supplied to the data converters 68b and 68c, where it is converted into CAD data 61b and 61c in the IGES format and DXF format, respectively, and then stored in an area corresponding to the format of the storage unit 10. Also, the CAD data in the MCAD format is stored in the corresponding area of the storage unit 10 as it is.
[0037]
When data save is selected on the startup screen of FIG. 3, the screen shown in FIG. 10 is displayed. In this data save screen, the file names and formats of all CAD data stored in the storage unit 10 are displayed in the column 70. The format and storage location of CAD data to be stored are designated in the columns 71a to 71c and 72a to 72c, respectively, and the file name is designated in the column 77. From this screen, by selecting buttons 73 to 75, any one of drawing diagnosis (conversion diagnosis of drawing to be saved), control parameter designation, and control parameter setting can be designated.
[0038]
When the above button 73 is selected, a drawing diagnosis is performed on the CAD data designated by the cursor, and the diagnosis result is displayed on the screen shown in FIG. In FIG. 11, regarding the CAD data to be converted, the number of each shape element such as a point or a line is displayed, and the number of each notation element such as a character string or a dimension is displayed. A diagnostic message is displayed by scrolling the display of FIG. This diagnostic message is an optimal control parameter setting guide and an optimal data format.
[0039]
When the button 75 is selected, control parameters are set. The format of this control parameter setting screen differs depending on the format of the conversion source CAD data and the conversion destination CAD data. FIG. 12 shows a control parameter setting screen when converting CAD data in MCAD format to DXF format. In FIG. 12, the presence / absence of conversion of graphic elements such as points, characters and labels, various sizes and layers, line type conversion, line width conversion, and the like are designated.
[0040]
FIG. 13 shows a flowchart of the storage process of the system of the present invention. This process is executed by the CAD device 14, and is started when a file name of CAD data to be saved is designated on the data save screen and the execution button 76 in FIG. 10 is selected.
[0041]
In FIG. 13, in step S <b> 30, the CAD data storage unit 65 temporarily stores the CAD data in the MCAD format displayed on the CAD device 14 in the storage unit 10. In step S32, it is determined whether or not drawing diagnosis is designated by selecting the button 73. When drawing diagnosis is performed here, the process proceeds to step S34, and the CAD data diagnosis unit 66 performs drawing diagnosis. As a result, if necessary, control parameters are set on the control parameter setting screen, and the process proceeds to step S36. If the drawing diagnosis is not performed (NO in step S32), the process directly proceeds to step S36.
[0042]
In step S36, the format of CAD data to be stored is selected. Here, the data format specified in the columns 71a to 71c in FIG. 10 is selected. Next, in step S40, it is determined whether or not the selected data format is the same as the format used for display in the CAD device 14, that is, the MCAD format. If not, the process proceeds to step S42, and if identical, the process proceeds to step S44. .
[0043]
In step S42, the CAD data in the MCAD format displayed on the CAD device 14 is converted into CAD data in the specified format using the data conversion program of the data converter corresponding to the format specified in the columns 71a to 71c, Thereafter, the process proceeds to step S44. In step S44, the CAD data converted into the MCAD format or the designated format is stored in the area designated in the columns 72a to 72c of the storage unit 10. At this time, the CAD data in the MCAD format is copied and stored from the temporarily stored area to a predetermined area. Next, storage information including the CAD data name, CAD data format, CAD characteristic value (contents of diagnostic message) and the like is stored in the storage unit 10 for the CAD data stored in step S46.
[0044]
Thereafter, in step S48, it is determined whether or not conversion and storage into all the data formats designated and selected in the columns 71a to 71c are completed. If not completed, the process proceeds to step S40, and steps S40 to S48 are repeated. If completed, the process is terminated.
[0045]
In this way, the operator automatically designates the CAD data displayed on the CAD device 14 simply by specifying the data format to be stored in the columns 71a to 71c and selecting the execution button 76 on the data save screen. Converted to all formats and stored.
[0046]
Also, if screen diagnosis is selected on the data load screen, a diagnostic message is output, and by setting a control parameter in accordance with this diagnostic message, the occurrence of a conversion error can be prevented. In other words, it is possible to prevent the conversion from being wasted due to the occurrence of a conversion error although the format conversion is attempted.
[0047]
