Abstract

PURPOSE:To improve drawing quality by automatically imparting a drawing number to a new drawing and a revision number to an altered drawing, thereby eliminating the time of drawing output to paper and the time of manual numbering, improving design efficiency, curtailing managing ledgers and personnel expenses, reducing managing expenses, and eliminating misnumbering due to misposting. CONSTITUTION:A control terminal receives a drawing number assignment command from one of drawing terminals S21, analyzes retrieval data in the command S22, and selects a classifying symbol in the retrieval data and collates it with the classification reference of a classification reference table S23, thereby finding the closest drawing number Fn in a registered drawing storage file when the reference agrees with it S23-Y. A drawing number imparting part sets the number right after the read drawing number Fn as a new drawing number S25, a drawing sending part transfers the newly imparted drawing number to the drawing terminal A S26, and a drawing number registration part registers the same drawing number in the registered drawing number file S27. When the reference does not agree with it S23-N, on the other hand, the misinput of the retrieval data is transferred to the plotting terminal and displayed S28.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to create a new design drawing (hereinafter simply referred to as "drawing") using a CAD terminal or to change a drawing that has already been registered. The present invention relates to a drawing management method and apparatus for automatically assigning a drawing number for management or a revised drawing number to a printer.

[0002]

2. Description of the Related Art Generally, a drawing is created by a design department and is used by the production department for reference when arranging materials, processing, assembling, and shipping products for manufacturing a product. Used to quote or modify when designing products.

Conventionally, drawing management of drawings has been performed as follows. When a designer newly creates a drawing using a CAD terminal, the drawing data is output to paper by a plotter, and the drawing is handed over to a drawing inspector to request drawing inspection.
If the drawing requires a correction note, the inspector endorses the drawing and returns it to the designer to instruct the correction, etc., and the designer writes the correction note endorsed in the drawing. Based on the data, the CAD terminal makes necessary corrections to the drawing data, and then the plotter again draws the drawing and delivers the corrected drawing to the inspector. The inspector again inspects the corrected drawing, and if it is OK, after manually signing the drawing, the drawing is handed over to the approver for approval. If a correction note is required for the contents of the drawing, the approver endorses the drawing and returns it to the designer to instruct correction, as in the case of the drawing inspector. The designer makes corrections and the like based on the endorsement, prints again on paper, and passes the corrected drawing to the approver via the drawing inspector. If the drawing inspector and the approver are drawing inspection OK and approval OK,
A signature is manually entered on each drawing to make it a completed drawing, and the completed drawing is handed over to the management department for registration and storage.

Before registering a completed drawing, the management department first manually gives a drawing number for management (hereinafter referred to as a drawing number). In this case, the drawing numbers are consecutive numbers for each model, but for new drawings, the next drawing number is assigned from the handwriting ledger that records the drawing numbers of the registered drawings, and that drawing number is used as the ledger. And posted on the drawing. Then, in order to register the drawing, the drawing with the drawing number is read by an image scanner, and at the same time, the drawing search data including the drawing number is input by key operation and stored in an electronic filing system such as an optical disk. ..

When the production department needs to obtain a specific drawing, the management department requests the management department to issue the drawing, and the management department uses the drawing search data in the electronic filing system to obtain the drawing. They searched the drawing data, printed out the corresponding drawings on a printer, and handed them over to the production department.

[0006] Further, when it is necessary to change (revise) the registered drawing, the predetermined items are entered in the drawing loan form and submitted to the management department to apply for the drawing borrowing, and the management department describes it in the drawing loan form. The drawing search data is input based on the drawing number, and the specified drawing is printed out by the printer, and the drawing loan is recorded in the ledger to manage the drawing. The serial number related to the registration number of the drawing before the change is numbered as the revised drawing number for the changed drawing, and this is entered in the changed drawing issued by the printer, and the date of change, the content of the change, the change After entering the change history such as locations, this drawing was read by an image scanner to register the changed drawing.

[0007]

[Problems to be Solved] As described above, conventionally,
To assign a number to a newly created drawing, manually search the handwritten ledger for the page containing the registered drawing number corresponding to the new drawing or changed drawing, and add the serial number or revision number next to the latest registered drawing number. Since it was numbered, posted on the ledger, and posted on the drawing that was issued, it took time to assign the drawing number, memory requirement was required, it is easy to make a transcription error, and it is issued due to drawing corrections, changes, etc. It was very troublesome because it needed to be transcribed each time.

Furthermore, when a drawing is changed, a designer other than the designer who is working is causing an unexpected trouble or making a change without knowing that the designer is quoting and referring to the drawing. That is, the production department, the shipping department, or the like does not know that it has been changed or changed, and there is a possibility that an unexpected accident may occur in the processing of the parts, the assembly, and the use of the product.
This is based on the fact that the drawings are in the process of being changed, or that the facts of the changes have not been promptly and reliably communicated in the drawings, drawing, drawing reference or citation.

Therefore, according to the present invention, in the drawing management apparatus for creating and managing the drawing by using the CAD terminal, the drawing number is automatically given and registered prior to the automatic registration of the new drawing. When changes are made to the drawing,
By automatically assigning the revised drawing number for the changed drawing, it is possible to improve the design efficiency by eliminating the drawing output time on paper and the manual numbering time, and reduce the management ledger and labor cost. The objective is to reduce management costs and to improve drawing quality by eliminating numbering mistakes due to transcription errors.

Further, when the drawing is changed, if the borrowing procedure of the already-registered drawing is carried out, the registered drawing can be lent out, so that the person who requests the drawing drawing citation, reference, change, etc. of the drawing during the change can be requested. It is an object to provide a drawing management device that notifies that a drawing is being changed, and that the changed person, the date of change, the reason for the change, the contents of the change, the changed portion, etc. can be easily recognized for the changed drawing.

And a signature entry field for entering the signature of the approver, and a name entry field for entering the part name, drawing number and drawing creation date. The part name is composed of a stratified classification and a search item name.

The stratified classification is based on attributes such as material, shape, processing method, and application of various parts, and common ones are classified into the same layer, and represented by a one-digit or two-digit alphabet symbol as an example. To be done. For example, A is a casting, B is a plate, C
Is a shaft, D is a gear, E is a roller, F is a spring, M is a resin, N is a name plate, P is a resistor, Q is a capacitor,
R is a relay, X is an integrated circuit ...

The retrieved item name is the ordinary name of the part expressed in ordinary terms. For example, if it is a plate, enter "plate". For example, in the case of a plate used for a shutter, a plate / shutter or the like may be added by adding a product name standard indicating the purpose of use to the searched product name.

When a drawing frame 343 as shown in FIG. 9 is displayed on the screen of the display unit based on the execution of the "drawing frame reference" command, the attribute information display field 344 on the left side of the display screen is displayed. As described above, an item to be set as the attribute information of the part shown in the drawing is displayed, and each time the item is selected by the mouse 32, the data box (in place of the title block is displayed at the position of the title block 343a). A setting item entry field 343b is displayed, and it is requested to enter setting items in this field (S13). The designer can use the word processor function of this CAD to fill in each entry field.

In the step of entering the title field (S13), the mouse 32 and the keyboard 31 are used to first enter the layer classification code (layer code) and the search item name or even the item name standard in the name entry column. To be done. Next, each attribute is entered in the attribute entry field. The stratified symbols, the search item name, and data up to the item name standard are used as the search data of the drawing information.

The items set in S13 are stored as a part of the attribute information of the parts drawing. Of the setting items, those that match the items entered in the title block 343a
It is automatically displayed in each entry column of the title block. In this case, the drawing number which is the search data is automatically assigned by the automatic numbering method according to the present invention described later. Of the above setting items, when the part name (layer classification symbol and search product name) is keyed in and the command of "new numbering" is executed, the automatic numbering program by the management terminal E is executed, and the same layer classification The number next to the registered number is adopted as the drawing number for this part drawing.

Following the completion of the work of entering the title column, the designer executes the "sign" command to call the designer's signature registered in advance, and enter the signature entry column of the designer in the drawing frame. Write and display (S14). In addition,
Since this signature is unique to each designer, in order to prevent it from being abused by others, only when the designer enters his or her password when executing the "sign" command, A program is constructed so that the image data of the signature is read out and added to the drawing frame.

When the drawing is completed by entering the signature as described above, when the "end" command is executed, the storage control means 46 of the CPU 39 causes the drawing data and the search data to be stored in the drawing drawing storage file A of the HDD 37.
It is stored in c (S15).

Subsequent to the storage of the drawing, the work of registering the attribute information is performed by the designer. As described above, this attribute information is composed of the items input in the step of entering the title column, and is registered in the HDD based on the attribute information registration command (S16).

[Automatic Numbering] After registering the attribute information, the automatic numbering of the new drawing number, which is the main part of the present invention, is performed by the automatic numbering function of the management terminal E (S17). The drawing terminal A
As shown in FIG. 11, the drawing terminal A is provided with the terminal number of the terminal, the search item name and the stratified classification in order to automatically assign the drawing number to the new drawing created by The numbering requesting means 111 for transmitting the numbering command including the number to the management terminal E, the attribute information inputting means 112 for inputting the above attribute information, and the drawing number received from the management terminal were drawn by the drawing terminal. The image data is composed by combining it with the drawing data of the drawing, and the drawing number is added to the attribute information input from the attribute information input means to form character data. Registered data for each edited data
Registration request means 114 for making a registration request to the registration terminal D, and the registration terminal D divides the data given from the registration request means 114 of the design terminal into image data and character data, and registers them in the drawing storage file Dd for each model. It has a data registration means 115 for.

Further, the management terminal E stores a registration drawing number storage file 116 for continuously storing drawing numbers of already registered drawings for each layer classification, and a drawing classification standard composed of a retrieved product name and a layer classification symbol. Of the classification standard table 117, the collating unit 118 that collates the search item name and the stratification symbol with the classification standard of the classification standard table in the data included in the numbering command received from the CAD terminal, and the matching and matching search. A search unit 119 that searches for the latest registered drawing number in the drawing number storage file based on the product name and the layer code, and a drawing number assigning unit 120 that assigns the next consecutive number to the searched latest registered drawing number, CA in which the drawing number is specified by the terminal number included in the numbering command
It comprises a drawing number sending unit 121 for sending to the D terminal, and a drawing number registration unit 122 for sequentially registering the assigned drawing numbers in the areas corresponding to the same layer classification of the drawing number storage file.

With the above configuration, in the drawing terminal A, in step 17 of FIG. 8 following the input of the attribute information, the command of "new numbering" is executed as shown in detail in FIG. 10 (S171), and thereafter. Then, it is checked whether or not a new drawing number is received from the management terminal E (S173), and if it is received, the new drawing number is stored in the drawing drawing storage file Ac (S).
174) together with the figure number “B10” in the figure number entry column of the title column displayed on the display screen of the display unit 34 in FIG.
"01" is displayed (S175) to notify that the automatic numbering is completed.

Then, the automatic numbering in FIG. 8 (S17)
When the drawing request command is executed by specifying the terminal number of the drawing terminal of the transfer destination by key input in the step of creating the transfer data format of S18 after the completion of the drawing, the data sending means 45 causes the drawing drawing storage file Ac of the HDD 37 to be executed.
The drawing information (drawing data, search data, and attribute information) is read from the drawing information, and drawing information including the terminal number of the drawing terminal is given to the predetermined downstream side specified by the terminal number via the communication control unit 36. The data is transferred to the drawing inspection terminal B and stored in the unexamined drawing drawing storage file Bd of the HDD 37 of the drawing inspection terminal.

While waiting for the reception of the new drawing number in S172 of FIG. 10, the management terminal E automatically assigns numbers based on the transfer of the numbering command from the drawing terminal A as shown in FIG. The program is executed. That is, when the management terminal E receives the numbering command from any of the drawing terminals A (Yes in S21), the collating unit 118 analyzes the search data included in the numbering command (S2).
2) If a stratified symbol is selected from the search data and the stratified symbol is collated with the classification standard registered in the classification standard table 117 (S23), and if it matches (Y in S23).
Gives the layer-by-layer symbol to the retrieval unit 119, finds the drawing number Fn of the registered drawing corresponding to the layer-by-layer symbol in the registered drawing number storage file 116, and gives this to the drawing number assigning unit 120 (S
24).

The drawing number assigning unit 120 sets the number next to the read drawing number Fn (that is, the number of Fn + 1) as a new drawing number, and the drawing number is sent to the drawing number sending unit 121 and the drawing number registration unit 12
Give to two. As shown in FIG. 13, the stratified symbol B and the serial number (1, 2 ... 1000) are registered in the already-registered drawing number register (table) composed of the registered drawing number storage file 116. In the example of FIG. 13, the latest registration number is B1000.
Is. Therefore, B1001 is assigned as a new drawing number when the next new drawing is created in the same layered section.

The drawing number sending unit 121 transfers the newly added drawing number to the drawing terminal A (S26), and the drawing number registration unit 122 registers the same drawing number in the registered drawing number storage file 116. (S27), the automatic drawing number assignment ends. Drawing terminal A
When the search data included in the numbering command received from does not match the classification standard (N in S23), the fact that the search data has been input is transferred to the drawing terminal (S2).
8) Display on the display unit of the drawing terminal.

Citation of drawing frame (S12), entry of title column (S13), entry of signature (S)
14), drawing storage (S15), attribute information input (S1)
6) The order of automatic numbering (S17) is merely an example and is completely arbitrary. For example, search data and other attribute information may be input in S11, and automatic numbering may be subsequently performed.

Returning to the drawing flow of FIG. 8, the drawing terminal A
Receives the drawing information sent back from the CAD terminal on the downstream side, that is, the drawing terminal B or the approval terminal C in the case of the drawing NG or the approval NG, and receives the drawing correction request ( In S10 affirmative), routines S19 to S114 and S18 for adding / subtracting correction to the drawing information are executed.

That is, in the received drawing information, the portion or item requiring correction is judged from the contents of the correction note added by the inspector or approver (S19). In the case of drawing NG, the designer Performs the modification work of the drawing according to the modification note data from the lower layer terminal (S110), and then stores the drawing data based on the execution of the store command (S110).
111). Following the storage of the drawing data, or if the drawing is not NG, it is determined whether the attribute information is NG without performing the drawing correction (S112). If the attribute information is NG, the attribute information is corrected according to the correction note data ( S113). After the correction of the attribute information, the drawing data of the changed drawing, the search data, and the attribute information are transferred to the predetermined drawing inspection terminal B by executing the drawing inspection request command (S18).

The drawing terminal A, based on the drawing request command execution, draws all the drawing data, search data and other attribute information created therein, and draws the drawing terminal B on a predetermined downstream side.
However, the data for which the drawing inspection request has been made remains in the design terminal. Then, when data is sent back from the drawing terminal or approval terminal for check NG, the data of the design terminal for the same drawing number is replaced with the drawing data and correction note data sent back. .. Therefore, after the drawing inspection request, the designer and the drawing inspector or the approver can mutually confirm the drawing contents until the inspection and approval are completed.

[Inspection] When data of a newly created drawing or a modified drawing is transferred from the drawing terminal A to the drawing terminal B, first, this data is stored in the HDD of the drawing terminal.
It is stored in the unexamined drawing drawing storage file Bd. Continuing from this, from the command types displayed on the display,
When "Inspection" is selected, the inspection program is executed, and as shown in the inspection flow of FIG. 15, the drawing information {drawing data and search data (title) stored in the unexamined drawing storage file Bd of the HDD 37 is displayed. Field entry)} is read out and displayed on the display unit (S31).

Next, in the drawing inspection terminal, if the entire drawing and all the changed items are displayed on the same screen, they are all displayed in a small size, and it is difficult for the inspector to make a change note. Therefore, in this drawing inspection terminal, after drawing the drawing, the screen state is set so that the correction note for the displayed drawing is enlarged and displayed in a size in which it is easy to input (S32).

The drawing inspector sequentially checks the displayed drawing and the entry items in the title column, and further other attribute information, and selects the drawing inspection OK or the inspection NG command according to the check result (S33). ). If the check result is good, the inspection drawing OK is input, and it is determined whether the drawing is a new drawing or a corrected drawing based on the drawing number of the search data (S34). In the case of a new drawing, the "sign" command is executed to read out the signature registered in advance and fill it in the predetermined signer signature entry field.

On the other hand, if the drawing is a corrected drawing, that is, if it is a redrawing drawing that has been inspected once, the correction note data added in the previous drawing inspection is erased by the data erasing means. (S35) After that, the process proceeds to step S36 for entering a signature. When the OK drawing command is executed (S37) after the signing is completed, the data remaining in the HDD, that is, the corrected drawing data sent from the drawing terminal A, the search data and the attribute information are transferred. The means moves to the approval terminal C via the communication control unit (S38). The designation of the approval terminal C may be fixed such that the terminal number of the predetermined approval terminal C is automatically set, but the inspector may specify the terminal number each time by key input.

In step S33 for checking the drawing,
If the check result is NG, it is determined whether the drawing at that time is a new drawing or a modified drawing (S39), and if it is a new drawing, a routine for entering the modified note data is executed (S311). ). That is, the symbols necessary for the correction note are read from the correction note reference file Be,
This is used to fill in the modified notes. When the inspector corrects each correction item in the drawing and the attribute information, the original drawing before the inspection and the correction note are combined and displayed on the inspection terminal B in a superimposed manner. In order to make it easy to understand that the correction note is the data related to the drafter's creation, the drawing terminal A
It is displayed in a different color from the original drawing.

On the other hand, in the case of the corrected drawing, the input operation for deleting the portion determined as the correction OK (S3
After performing 10), the correction note is entered in step S311. Then, when the command of the inspection NG is executed after the correction note entry is completed (S312), the data including the correction note data causes the communication control unit 36 to transfer the data including the correction note data.
It is sent back to the drawing terminal A involved in the drawing creation via (S313). In this case, the drawing data is moved to the drawing terminal A and does not remain in the inspection terminal B.

In the drawing terminal A, the original drawing initially created and the correction note added by the inspector are displayed in an overlapping manner on the display unit 34, and the correction note is displayed in a color different from that of the original drawing. Is displayed. Therefore, the drawing created by the designer and the corrections and notes entered by the drawing inspector can be clearly identified.

[Approval] By the inspection drawing OK, the approval terminal C to which the drawing information is transferred from the drawing inspection terminal B stores the data in the unapproved drawing storage file Cd of the HDD of the approval terminal. Then, when the approval terminal C is started, the approval program is executed, and as shown in FIG. 16, the drawing information (drawing data and search data) is read from the HDD and displayed on the display unit (S41). Then, as in the case of the inspection terminal B, the drawing state is set (S42). The approver checks the displayed figure and the entry items in the title block,
The command of approval OK or approval NG is executed according to the result of the check. The CPU judges whether approval is OK or NG from the execution of the command (S43), and if approval is OK,
Proceed to the step for signing a signature, and based on the approver's execution of the "sign" command and password input or input for specifying the signature, the specified signature is read from the memory and entered in the signature entry field of the drawing frame. Yes (add data). When the approval OK command is executed following this signature entry (S45), the drawing information of the unapproved drawing storage file Cd of the HDD is the approved drawing storage file C.
It is moved to f (S46). Until the drawing creation of the related parts of one model is completed, the approval drawing storage file Cf is stored. The correction note data input at the terminal itself is erased by the data erasing means.

When all the related parts, that is, all the constituent parts of the product of one model have been drawn (S47)
In Y), the approval drawings accumulated in the approval drawing storage file Cf are collectively stored in the registration drawing storage file Dd of the predetermined registration terminal D by executing the drawing completion command from the approval terminal C and designating the terminal number. It is moved and registered (S48).

Incidentally, the drawing information is moved to the approval drawing storage file Cf by the approval OK, but the registration terminal D directly without the approval drawing possible file Cf.
It may be moved to the registered drawing storage file Dd. However, in order to improve the efficiency of operation, it is better to use the approval drawing storage file Cf.

On the other hand, if the check result is NG (No at S43), the process proceeds to step S49 for the correction note based on the command execution, and the symbol read from the correction note reference file is quoted. Then, the annotation data for the portion to be corrected in the designer's drawing is entered by key operation or mouse operation. Then, by executing the approval NG command (S410), the drawing information and the correction note data are added to the drawing terminal A designated by the terminal number input before the data transfer means by adding the terminal number of the own terminal. It is sent back (that is, moved) to the drawing terminal A via the communication control unit (S411). In the drawing terminal A, the designer data and the approver data from the approval terminal C are overlaid on the display unit, and the drawing information (drawing data, search data, attribute information) is added or rewritten in accordance with the correction note. , Can be deleted.

When the registration of the drawing at the registration terminal D is completed,
The registration terminal reports the registration completion to the drawing terminal A, transfers the registration drawing data to the design terminal, and replaces the data in the drawing drawing storage file with this. As a result, the design terminal can confirm from the display screen that a series of drawing drawings have been registered, so the designer executes the delete command to empty the drawing drawing storage file Ac.

The registration terminal D, to which the drawing information has been moved from the approval terminal C, further provides the drawing drawing and the attribute information input at the design terminal and the drawing number assigned by the automatic numbering of the management terminal for each model. Is divided into drawing data, which is image data, and search data, which is character data, and the image data is searched data for the optical disc OM or the like via the electronic filing system connected to the registration terminal D. Is stored in a predetermined address of the optical disc as an address, and the attribute information is registered in the host computer F for use in creating a parts table.

[Drawing Revision and Automatic Numbering] As described above, it may be necessary to change the drawing data and / or attribute information, that is, revising the registered drawing created and registered. The revision can be performed on the CAD terminal, for example, the drawing terminal A. In addition, in order to automatically assign the drawing number of the revised drawing even when the edition is revised, as shown in FIG. 17, the function realizing means is added to the design terminal AE, the registration terminal DE, and the management terminal EE. ing. Subsequently, these added means will be described. Figure 1
Since each terminal of 7 is basically equivalent to the above-mentioned terminal, a code obtained by adding E to the code of the above-mentioned terminal is used. Also, the same reference numerals as those in FIG. 11 are used for the same components as those shown in FIG.

The design terminal AE has a drawing borrowing application data input unit 171, a drawing revision requesting unit 172, and a drawing changing unit.
173, change history data inputting means 174, revision numbering requesting means 175, drawing number replacing means 176, data editing means
113E and registration request means 114E are provided.

The drawing borrowing application data input means 171 is for inputting predetermined data, at least the drawing number and page for specifying the drawing and the terminal number data for specifying the transfer destination. The keyboard, the CPU 39 and , It consists of programs necessary for guiding and monitoring the data input required for drawing borrowing application. The drawing revision requesting means 172 sends a drawing revision requesting signal including the data inputted from the drawing borrowing application data inputting means to the registration terminal DE. The drawing change means 173 is for changing a registered drawing borrowed from the registration terminal DE and adding a change symbol to the drawing. Change history data input means 174
Is for inputting a change history such as date of change, reason for change, details of change, change symbol, name or signature of changer. The revision numbering requesting means 175 sends a revision numbering command for requesting the revision drawing number to the revised drawing to the management terminal EE. In the command, the registration drawing number and the terminal of the design terminal are included. The numbers and are included.
The drawing number replacing means 176 rewrites the drawing number of the registered drawing borrowed from the registration terminal DE with the revised drawing number received from the management terminal EE after the revised numbering request.
The data editing means 113 E is the data editing means 11 described above.
Similar to 3, the image data is configured by adding the revised drawing number and the change history data input from the change history data input means 174 to the drawing data revised by the drawing change means 173. The registration requesting means 114E requests the registration terminal DE to register the data edited by the data editing means.

Further, as in the case of the above-mentioned registration terminal, the registration terminal DE uses the data read / register means 115E and drawing data of the drawing and the revised drawing based on a specific drawing number or a revised drawing number, respectively. It has a drawing drawing storage area 177 for storing, a revised drawing storage area 178, and a change history storage area 179 for storing change history data.

The management terminal EE is provided with a drawing number storage file 116 E, a revised drawing number assigning means 120 E, a revised drawing number sending means 121 E, and a registration means 122 E.

The drawing number storage file 116E stores continuous drawing numbers for each stratified section of the registered drawings, as in the case of FIG. Revised drawing number giving means 120
E compares the drawing number included in the revision numbering command received from the design terminal AE with the already registered drawing number, and continuously sets and outputs the revised drawing number attached to the drawing number. ..
The revised drawing number sending means 121E transfers the revised drawing number given by the revised drawing number giving means 120E to the design terminal AE. The registration means 122E sequentially registers the revised drawing numbers given by the revised drawing number giving means 120E in the drawing number storage file 116E.

In the case of revising the registered drawing with the above configuration, first, the "drawing borrowing" command in the menu shown on the right side of the display screen 34 of FIG. 9 of the drawing terminal A is executed. Based on this, the CPU of the design terminal is
8 executes the revision program as shown in the flowchart, and in the first step S51, the management terminal EE cites the drawing borrowing application form data as shown in FIG. Display the display unit of terminal A and display the items required for drawing borrowing application, for example, the drawing number and page for identifying the registered drawing you want to borrow, the borrowing date, the department for recording the borrower, the name, and Prompt for input such as the terminal number to identify the transfer destination of drawing data. When the required data is input from the drawing borrowing application data input unit 171 of the design terminal AE, the data is registered by the drawing revision requesting unit 172 as the drawing borrowing request data.
It is given to E and waits for the drawing data to be rented from the registration terminal (S52).

During this period, the registration terminal DE is the design terminal AE.
The drawing specified by the drawing borrowing request data received from the drawing is called from the drawing storage file and transferred to the design terminal AE specified by the terminal number. In this case, the fact that the drawing is being rented for modification is recorded in the storage area of the rented drawing of the registration terminal, for example, by setting up a flag bit. When a request for drawing, quoting, referencing, borrowing, etc. is made from another CAD terminal and the host computer F to the drawing in which this flag bit is rising, the drawing is being changed for that terminal. Report that it is. Based on this, in the terminal that has executed a command such as “borrowing drawings” or “drawing”, the fact that the drawing cannot be drawn out or cannot be lent out is displayed on the screen of the display unit because it is being changed. ..

The designer of the design terminal that has rented out the registration drawing applied for from the registration terminal DE checks whether or not it is the borrowing application target drawing while looking at the drawing displayed on the display screen (S53). If the drawing is a borrowing application target drawing, the drawing changing means 173 can arbitrarily change the displayed parts drawing (S5).
4).

When the change to the changed drawing (S54) is completed, the management terminal E is executed following the execution of the "end" command.
The data of the drawing change processing application for recording the fact of the drawing change is quoted from E, the title column 343a and the change history column 343c are displayed on the part drawing of the display screen of the design terminal,
It is requested to fill in the title column 343a and the changed article in the change history column 343c (S55).

With respect to the drawing revision, the change data is processed so that the designer can immediately confirm the change history from the screen. That is, the change history column 343c is displayed on the right side of the title column 343a on the display screen. This change history column has a change count entry column, a change content entry column, a change reason entry column, a change date entry column, and a changer entry column. If you have changed the drawing, the position of the changed drawing,
A symbol having a numerical value of the number of changes, for example, a symbol enclosing the numerical value in a triangle is displayed. When multiple changes are made by one change, the same symbol is displayed at each change and the same symbol is automatically entered in the change number entry field. The change content entry field shows the figure before the change and the figure after the change. The change date entry field is populated with data from the calendar function of the day. In the changed drawing number display field, a drawing number obtained by combining the drawing number of the quoted drawing with a numerical value indicating the number of times of change by a hyphen is given by the automatic numbering function of the management terminal E.

In the example shown in FIG. 14, the first change is 1
On August 30, 991, the figure of the original drawing of the drawing number B1001 in FIG. 9 is changed from a triangle to a quadrangle. The second change was to change the true circle of the figure to an ellipse on August 31, 1991, and the changed figure number is B1.
001-2. This modified article
The change symbol, the change content, the change reason, the change date, the signature, and the like. This modified article can be filled by the word processing function.

When the change history data inputting means 174 enters the change history such as the date of change, the reason for change, the contents of change, the change symbol, the name or signature of the person who made the change, and the "end" command is executed, the change is made. The drawing data and the title block entries are stored in the image data storage file (S
56). The input change history information is also registered in the character data storage file (S57).

The main work for revision is completed by the above-mentioned drawing change and the input of revision history information, and subsequently, the revision numbering request means 175 executes the "numbering" command to automatically assign the revised drawing number. When the number is requested to the management terminal EE, the revised drawing number assigning means 120 E in the management terminal EE causes the design terminal A
Drawing number storage file 116E based on the drawing number received from E
Check the registration status of the pre-change drawing number, set the revised drawing number,
In order to give this to the drawing number sending unit 121 E and the registration unit 122 E, the drawing number sending unit 121 E sends the set revised drawing number to the design terminal AE, and the registration unit 122 E sends the revised drawing number. It is registered in the drawing number storage file 116E (S58).

Finally, when the "end" command is executed,
By the data editing means 113E, the revised drawing number is added to the drawing data of the changed drawing to form image data, and the revised drawing number and change history information are added to the attribute information to form character data. Register request means
114E, it is registered in the drawing drawing storage file.
Then, by executing the “drawing request” command, the drawing drawing storage file is transferred to each file of the unexamined drawing of the drawing terminal B (S58).

When the "registration" command is executed instead of the "drawing request" command, the drawing drawing storage file of the design terminal is moved to the registration terminal DE. Registration terminal D
In E, the data read registration means 115 E divides the data received from the design terminal into image data and character data, and changes them to the drawing drawing storage file 177 and the revised drawing storage file 178 which constitute the registration drawing storage file. It is stored in a predetermined area of the history storage file 179.

Although the host computer is used as the management terminal in the above embodiment, the present invention is not limited to this.

[0091]

As described above, according to the drawing management method according to the present invention and the drawing management apparatus according to the second aspect, it is possible to search and fill a handwritten ledger as in the conventional case with respect to a newly drawn drawing. , Continuous drawing numbers according to predetermined classification standards are automatically added by the necessary data input such as attribute information in the process of drawing without the need for troublesome manual work such as transcription on the drawn drawings. Since the output time to paper and the time to manually add drawing numbers are reduced, design efficiency is significantly improved,
In addition, the conventional management ledger, its storage space, and the labor cost required for survey entry / transcription are unnecessary, so that the management cost can be reduced. Further, since various mistakes in the conventional drawing number assignment can be prevented, the improvement of drawing management quality can be greatly expected.

According to the drawing management apparatus of the fourth aspect, when the registered drawing is changed, the revised drawing number related to the drawing number before the change is automatically added to the revised drawing. , In addition to the same effects as above, the registered drawings cannot be borrowed unless the procedure for applying for a drawing borrowing to enter the specified items is performed, and after the change, the change history of the specified items along with the changed drawings Since registration is performed, it is possible to achieve the effect that strict management can be realized when changing the registered drawing. It is also effective in preventing production problems.

Further, with respect to the changed drawing, the change symbol is entered on the drawing of the changed portion, and the change symbol is written in the changed article column.
Since the contents of change, date of change, signature, etc. are entered, it is possible to quickly and clearly know the difference between before and after the change when referring to the changed drawing.
