DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for creating and registering a drawing of a new part using a CAD terminal, or for changing and registering an already registered drawing. The present invention relates to a drawing management method and apparatus for automatically assigning and managing a drawing number for management (hereinafter referred to as a drawing number) or a revised drawing number (hereinafter referred to as a revised drawing number).

[0002]

2. Description of the Related Art In general, drawings are created by a design department, and are used by a production department for reference when arranging, processing, assembling and shipping products for manufacturing products. Used to quote, modify, or change product designs.

Conventionally, drawing management of drawings has been performed as follows. When a designer newly creates a drawing using a CAD terminal, the figure data is output to paper by a plotter, and the drawing is handed over to a checker to request a check.
If the drawing requires a correction note on the drawing, the planner endorses the drawing and returns it to the designer to give instructions such as correction, and the designer checks the correction note on the drawing. After making necessary corrections to the graphic data by the CAD terminal, the plotter issues the drawing again, and delivers the corrected drawing to the inspector. The checker checks the corrected drawing again. If the drawing is OK, the signer manually fills in the signature and hands over the drawing to an approver to request approval. The approver, when the drawing content requires a correction note, as in the case of the drawing checker, endorses the drawing and returns it to the designer to instruct correction. The designer makes corrections and the like based on the endorsement, prints it again on paper, and hands over the corrected drawing to the approver via the drawing inspector. If the checker and approver are OK and OK,
Each of the drawings is manually filled with a signature to be a completed drawing, and the completed drawing is handed over to a management department for registration and storage.

[0006] Before registering a completed drawing, the management department first manually assigns a drawing number for management. In this case, the drawing numbers are consecutive for each model, but for a new drawing, the next drawing number is assigned from the handwritten ledger that records the drawing numbers of the registered drawings, and that drawing number is recorded in the ledger. And transcribed it into the drawing. In order to register a drawing, the drawing on which the drawing number is entered is read by an image scanner, and at the same time, drawing search data including the drawing number is input by key operation and stored in an electronic filing system such as an optical disk. .

[0005] When the production department needs to obtain a specific drawing, the production department requests the management department to release the drawing, and the management department uses the drawing search data in the electronic filing system to perform the necessary drawing. They searched the drawing information, published the relevant drawing on paper with a printer or the like, and handed it to the production department.

[0006] Further, when it is necessary to change (revise) the registered drawings, fill in the prescribed items in the drawing borrowing document, submit it to the management department, apply for drawing borrowing, and the management department writes in the drawing borrowing document. Based on the drawing number entered, input the drawing search data, release the predetermined drawing with a printer, record the drawing rental in the ledger, manage the drawing, and based on the completion of the drawing change, A serial number related to the registration number of the drawing before the change is numbered as a revised drawing number for the changed drawing, this is entered in the changed drawing released by the printer, and the change date, change contents, change After writing the change history of the location and the like, the drawing was read by an image scanner to register the changed drawing.

[0007]

As described above, conventionally,
Numbering of newly created drawings is performed by manually searching the handwritten ledger for the page with the registered drawing number corresponding to the new drawing or changed drawing, and the next sequential number or revision number of the latest registered drawing number Numbering, bookkeeping in the ledger, and posting to the issued drawing, it takes time to assign the drawing number, memory is required, it is easy to cause transcription errors, and drawing out by drawing correction, change, etc. It had to be transcribed every time it was done, which was very cumbersome.

Further, when a drawing is changed, unexpected troubles may occur or the designer may change the drawing without knowing that the drawing is being changed when a designer other than the designer who is working is quoted or referred to the drawing. The production department, shipping department, or the like may unknowingly notify the production department, the shipping department, or the like of the fact that there has been a risk of causing an unexpected accident in processing, assembling, or using the product.
This is based on the fact that the drawing is being changed or the fact that the changed fact has been displayed on the drawing, released, referred to or referred to in the drawing, or was not promptly and reliably transmitted.

Therefore, according to the present invention, in a drawing management apparatus for creating and registering a drawing by using a CAD terminal, prior to automatic registration of a created new drawing, a drawing number is not required at all without drawing on paper. Is automatically added to the drawing information, and when a change is made to the registered drawing, the revised drawing number of the changed drawing is automatically added without any need for release to paper. To improve the drawing efficiency by deleting the drawing output time to paper and the manual numbering time by adding the information to the drawing information and adding it to the drawing information;
An object of the present invention is to reduce management costs by reducing management ledgers and personnel costs, and to improve the reliability of drawing management by eliminating mistakes in numbering due to transcription errors and the like.

[0010] Further, it is possible to rent a registered drawing without the need for paper power and to perform the borrowing procedure of a registered drawing at the time of drawing change, without needing to publish it on paper at all. Citation, reference,

When the power to the drawing terminal A is turned on, the CPU 3
Reference numeral 9 designates, first, the readout means 41 and the display means 42, at a predetermined display position 341 on the display surface of the display unit 34, the type of command to be designated, that is, a character for designating the business content to be operated next by this terminal. Are displayed in a predetermined arrangement order. In the illustrated apparatus, as shown in FIG. 9, “drawing”, “checking”, “approval”, “registration”, “quoting of drawing frame”, “new numbering”, “borrowing drawing” representing the content to be executed in each terminal are performed.
Characters such as “discontinued number”, “drawing rental”, and “sign” are displayed to urge input (selection) of the business content to be executed next. In the illustrated example, since all terminals from the check terminal to the registration terminal also have a drawing function, the above-mentioned "check", "approval", and "registration" are also displayed.

FIG. 8 shows an operation flow when the command of "drawing" is executed. Hereinafter, in each figure, the combination of S and a number means a step. The drawing terminal A is used not only for creating a new drawing, but also for correcting a drawing reversely sent from a check terminal by a check NG or a drawing returned from an approval terminal by an approval NG. When "drawing" is selected, first, it is determined whether or not there is a correction request from the drawing check terminal or the approval terminal by checking whether or not the drawing drawing storage file Ac in the HDD 37 stores the corrected drawing (S1).

When the command of “drawing frame quote” is executed during or after the drawing, the drawing frame quote file De stored in the registration area 57d of the registration terminal D is displayed as shown in the center of the display screen of FIG. A drawing frame 343 having a title field 343a composed of a plurality of entry fields on the lower side is read out and displayed on the same display surface as the drawing (S12).

A title field 343a of the drawing frame 343 is an attribute entry field for items relating to the attribute of the part, such as the type of surface treatment, the type of heat treatment, and the material, of the part represented by the drawing, and the designer and the figure inspector. And a sign entry column for entering the signature of the approver, and a name entry column for entering the part name, drawing number, and drawing creation date. The part name includes a stratified symbol and a search item name.

The stratified symbols are used to classify common components into the same layer based on attributes such as the material, shape, processing method, and application of various parts. For example, one or two digits are used. It is represented by the alphabet symbol. 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 nameplate, P is a resistor, Q is a capacitor, R is a relay, X is a relay, Integrated circuit, etc.

The search item name is an expression of a common name of the part in an ordinary term. For example, if the object is a plate, enter “plate”. For example, in the case of a plate used for a shutter, a plate / shutter may be written in addition to a product name standard indicating a use or the like to the search 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 command of “quoting drawing frame”, the attribute information display field 344 on the left side of the display screen is displayed. As shown in the figure, an item to be set as attribute information of the part represented by the drawing is displayed, and each time the item is selected by the mouse 32, data is displayed in the position of the title box 343a instead of the title box. A box (attribute information entry field) 343b is displayed, and it is requested to enter a setting item in this box (S13). The designer
By using the word processing function of the CAD, it is possible to fill in each entry column.

In the title box entry step (S13), first, the symbol of the stratification classification (symbol by stratification) and the name of the retrieval item, or further up to the item name standard are entered in the name entry column using the mouse 32 and the keyboard 31. Is done. Next, each attribute is entered in the attribute entry field. The stratified symbol, the search item name, and data up to the item name standard are used as search data for the drawing information. The figure number is also one of the search data.

The items set in S13 are stored as part of the part drawing attribute information. Of the setting items, those that match the entries in the title box 343a
It is automatically displayed in each entry box in the title box. In this case, the figure number as search data is automatically given by an automatic numbering method according to the present invention described later. When the part name (layer symbol and search item name) among the above setting items is input by a key and a "new numbering" command is executed, an automatic numbering program by the management terminal E is executed, and The number following the registered number is adopted as the drawing number of this part drawing.

Following completion of the entry work in the title box, the designer executes a “sign” command to call the pre-registered signature of the designer, and to enter the signature entry field of the designer in the drawing frame. Write and display (S14). In addition,
Since this signature is unique to each designer, 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 configured to read the image data of the signature and add it to the drawing frame.

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

Following storage of the drawing, the designer registers the attribute information. As described above, this attribute information is composed of the items input in the title box entry step, and is registered in the HDD based on the attribute information registration command (S16).

[Automatic Numbering] After the registration of the attribute information, the automatic numbering of the new drawing number, which is a main part of the present invention, is performed by the automatic numbering function of the management terminal E (S17). Automatically assigning a drawing number to a new drawing created by the drawing terminal A, that is, in order to perform automatic numbering, the drawing terminal A is provided with the terminal number of the terminal and the search item name as shown in FIG. Numbering requesting means 111 for sending a numbering command including a stratified classification to the management terminal E
Attribute information input means 11 for inputting the attribute information
2 and the drawing number received from the management terminal is combined with the graphic data of the drawing drawn by the drawing terminal to compose the image data, and the drawing number is added to the attribute information input from the attribute information input means. It has data editing means 113 for subscribing and forming character data, and registration requesting means 114 for making a registration request to the registration terminal D for the data edited by said data editing means. Has data registration means 115 for dividing the data given from the registration request means 114 into image data and character data and registering them in the drawing storage file Dd for each model.

Further, the management terminal E stores a registered drawing number storage file 116 for continuously storing the drawing numbers of the registered drawings for each stratified division, and a drawing classification criterion composed of a retrieval product name and a stratified symbol. And a collating unit 118 that collates a search item name and a stratified symbol among the data included in the numbering command received from the drawing terminal with the classification standard of the classification standard table. A search unit 119 that searches for the latest registered figure number of the figure number storage file based on the product name and the stratified symbol, and a figure number assigning unit 120 that assigns a serial number next to the searched latest registered figure number; A drawing number sending unit 121 that sends a drawing number to a drawing terminal specified by a terminal number included in the numbering command, and stores the given drawing number in an area corresponding to the same stratified division of the drawing number storage file. Drawing number registration unit 122 to be registered sequentially It has.

According to the above configuration, the drawing terminal A executes the "new numbering" command in step 17 of FIG. 8 following the input of the attribute information, as shown in detail in FIG. 10 (S171). It is checked whether a new drawing number has been received from the later-described management terminal E (S172). If received, the new drawing number is stored in the drawing drawing storage file Ac (S172).
173) together with the figure number "B10" in the figure number entry field of the title field displayed on the display screen of the display unit 34 in FIG.
01 is displayed (S174) to notify that the automatic numbering has been completed.

Then, the automatic numbering in FIG. 8 (S17)
After the completion of the process, in the transfer data format creation step of S18, when the terminal number of the transfer destination check terminal is designated by key input and the check request command is executed, the data sending means 45 causes the HDD 37 to store the drawing drawing storage file Ac in the HDD 37.
The drawing information (graphic data, search data, and attribute information) is read out from the CPU, and the drawing information including the terminal number of the drawing terminal is transmitted via the communication control unit 36 to a predetermined downstream side designated by the terminal number. The file is transferred to the check terminal B and stored in the unchecked drawing storage file Bd of the HDD 37 of the check terminal.

While waiting for reception of a new figure number in S172 of FIG. 10, the management terminal E automatically assigns a number based on the numbering command transferred from the drawing terminal A as shown in FIG. Is executed. That is, when the management terminal E receives a numbering command from one of the drawing terminals A (Yes at S21), the collating unit 118 analyzes the search data included in the numbering command (S2).
2), a stratified symbol is selected from the search data, and the stratified symbol is collated with the classification criteria registered in the classification criteria table 117 (S23), and when they match (Y in S23).
Gives the stratified symbol to the search unit 119, finds the figure number Fn of the registered drawing corresponding to the stratified symbol in the registered figure number storage file 116, and gives it to the figure number assigning unit 120 (S
24).

The figure number assigning section 120 sets the number next to the read figure number Fn (that is, the number of Fn + 1) as a new figure number, and uses the figure number as the figure number sending section 121 and the figure number registering section 12.
2 (S25). As shown in FIG. 13, the registered figure number ledger (table) composed of the registered figure number storage file 116 has a stratified symbol B and a serial number (1, 2,..., 10).
00) is registered. In the example of FIG. 13, the latest registration number is B1000. Therefore, B1001 is assigned as a new drawing number when a next new drawing of the same layer division is created.

The figure number sending unit 121 transfers the newly given figure number to the drawing terminal A (S26), and the figure number registration unit 122 registers the same figure number in the registered figure 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 the server does not match the classification criteria (N in S23), the fact that the input of the search data is an error is transferred to the drawing terminal (S2).
8) Display on the display unit of the drawing terminal.

In the process of creating the new drawing, the drawing frame is quoted (S12), the title box is entered (S13), and the signature is entered (S
14), drawing storage (S15), attribute information input (S1)
6) The order of the automatic numbering (S17) is merely an example, and is completely arbitrary. For example, in S11, search data and other attribute information may be input, and then automatic numbering may be performed.

Returning to the drawing flow of FIG.
Receives the drawing information transmitted in the case of the inspection NG or the approval NG from the downstream CAD terminal, that is, the inspection terminal B or the approval terminal C, and receives a request for the drawing correction ( In S10 affirmative), routines S19 to S113 and S18 for adding, subtracting and correcting the drawing information are executed.

That is, of the received drawing information, a portion, an item, and the like that needs to be corrected are judged from the contents of the correction note added by the checker or approver (S19). Performs the modification work on the drawing in accordance with the modification note data from the lower layer terminal (S110), and stores the graphic data based on the execution of the storage command (S110).
111). Subsequent to storage of the graphic data, or if the drawing is not NG, it is determined whether or not the attribute information is NG without modifying the drawing (S112). If NG, the attribute information is corrected according to the correction note data ( S113). After the correction of the attribute information, the graphic data, the search data, and the attribute information of the changed drawing are transferred to the predetermined check terminal B by executing the check request command (S18).

The drawing terminal A sends all the graphic data, search data and other attribute information created there to a predetermined downstream drawing terminal B based on the execution of the check request command.
The data requested to be checked is also left at the design terminal. Then, when the data is sent back for check NG from the drawing check terminal or the approval terminal, the data of the design terminal for the same drawing number is replaced with the graphic data and the correction note data sent back. . Therefore, after requesting a check, until the check and approval are completed, the designer and the checker or the approver can mutually confirm the drawing contents.

[Checking] In the checking terminal B, when data of a newly created drawing or a changed drawing is transferred from the drawing terminal A, first, the data is unchecked in the HDD of the checking terminal. It is stored in the drawing drawing storage file Bd. Subsequently, when "check" is selected from the command types displayed on the display unit, the check program is executed, and as shown in the check flow of FIG. File Bd
Is read out and displayed on the display unit (S3).
1).

Next, in the check terminal, if the entire drawing and all the changed items are displayed on the same screen, all of them are displayed in a small size, making it difficult for the checker to make a note of the change. Thus, in the check terminal, after the drawing is quoted, a screen state for enlarging and displaying a correction note for the displayed drawing to a size easy to input is set (S32).

The checker sequentially checks the displayed drawings and the entries in the title box, as well as other attribute information, and selects a check OK or check NG command according to the check result (S33). ). If the check result is good, the user inputs "OK" to check whether the drawing is a new drawing or a corrected drawing based on the drawing number of the search data (S34). If the drawing is a new drawing, a "sign" command is executed to read out a pre-registered sign and to fill in a predetermined figure checker sign entry field (S36).

On the other hand, if the drawing is a corrected drawing, that is, if it is a re-check of a drawing that has been checked once, the correction note data added during the previous check is deleted by the data deleting means ( S35) Then, the process proceeds to signature entry step S36. After signing is completed, OK
When the command is executed (S37), the data remaining in the HDD, that is, the corrected drawing information (graphic data, search data, and attribute information) sent from the drawing terminal A is deleted.
The data transfer unit moves to the approval terminal C via the communication control unit (S38). The designation of the approval terminal C may be fixed so that the terminal number of the predetermined approval terminal C is automatically set, or the checker may specify the terminal number each time by key input.

In step S33 of the drawing check,
If the check result is NG, it is determined whether the drawing at that time is a new drawing or a corrected drawing (S39). If the drawing is a new drawing, a routine for entering correction note data is executed (S311). ). That is, symbols and the like necessary for the correction note are read from the correction note citation file Be,
A correction note is entered using this. Then, when the checker corrects each correction item for the drawing and the attribute information, the original drawing before the check and the correction note are combined and displayed on the check terminal B. The correction note is drawn on the drawing terminal A in order to clearly indicate that it is data related to the creation of the checker.
Is displayed in a different color from the original drawing.

On the other hand, if the drawing is a correction drawing, an input operation (S3) for deleting the portion determined to be correction OK.
After performing 10), the correction note in step S311 is entered. Then, after completing the correction note entry, when the command of the check NG is executed (S312), the data including the correction note data is transmitted to the communication control unit 36 by the data transfer means.
Is sent back to the drawing terminal A involved in the drawing creation (S313). In this case, the drawing information is moved to the drawing terminal A and does not remain in the drawing terminal B.

In the drawing terminal A, the original drawing initially created and the correction note added by the checker are displayed on the display section 34 in a superimposed manner, and the correction note is displayed using a different color from the original drawing. Is displayed. Therefore, the drawing created by the designer can be clearly distinguished from the correction items and notes entered by the checker.

[Approval] In the approval terminal C to which the drawing information has been transferred from the check terminal B by the check OK, the data is stored in the unapproved drawing storage file Cd of the HDD of the approval terminal. Then, based on the start of the approval terminal C, the approval program is executed, and FIG.
As shown in FIG. 6, drawing information (graphic data, search data, and attribute information) is read from the HDD and displayed on the display unit (S41). Then, similarly to the check terminal B, the drawing state is set (S42). The approver checks the displayed figure and the entry in the title box, and executes a command of approval OK or approval NG according to the check result. The CPU determines from the command execution whether the approval is OK or NG (S43). If the approval is OK, the CPU proceeds to step 44 for signing, executes the "sign" command of the approver, and inputs the password or specifies the sign. A predetermined signature is read out from the memory based on the input for (1), and is written in the signature entry field of the drawing frame (data is added). When the approval OK command is executed following the signature entry (S45), the drawing information of the unapproved drawing storage file Cd in the HDD is moved to the approved drawing storage file Cf (S46). Until the drawing creation of one type of related parts is completed, the parts are accumulated in the approval drawing storage file Cf. Corrected note data input at the terminal itself is deleted by the data deleting means.

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

It should be noted that the drawing information is moved to the approved drawing storage file Cf by approval OK. However, the drawing information is directly transferred to the registration terminal D without the approval drawing available file Cf.
May be moved to the registered drawing storage file Dd. However, in order to improve the operation efficiency, it is better to use the approval drawing storage file Cf.

On the other hand, if the result of the check is NG (No at S43), based on the execution of the command, the flow proceeds to step S49 for correction note, and quotes the symbol read from the correction note reference file. Then, correction note data for a portion to be corrected in the drawing of the designer is entered by a key operation or a mouse operation. Then, by executing the approval NG command (S410), the drawing information and the correction annotation data are added to the drawing terminal A designated by the previously input terminal number by adding the terminal number of its own terminal to the data transfer means. It is sent back (ie, moves) to the drawing terminal A via the communication control unit (S411). The drawing terminal A superimposes the designer data and the approver data from the approval terminal C on the display unit, and adds and rewrites the drawing information (graphic data, search data, attribute information) according to the correction note. , Delete, etc.

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

The registration terminal D, to which the drawing information has been moved from the approval terminal C, further stores, for each model, the drawing and the attribute information inputted at the design terminal and the drawing number given by the automatic numbering of the management terminal. Is divided into graphic data as image data and search data as character data, and the image data is transmitted to an optical disc MO or the like via an electronic filing system connected to the registration terminal D, and is used as search data. Is stored at a predetermined address of the optical disk 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, there may be a case where a change regarding graphic data and / or attribute information, that is, a revision, is required for a registered drawing created and registered. The revision can be performed at the CAD terminal, for example, the drawing terminal A. Also, at the time of revision, in order to automatically assign the drawing number of the revised drawing, as shown in FIG.
A function realizing means is added to E, the registration terminal DE, and the management terminal EE. Subsequently, the added means will be described. Each terminal in FIG. 17 is basically equivalent to the above-described terminal, and thus, the code of the above-described terminal is E
Are used. Further, the same components as those shown in FIG. 11 are also denoted by the reference numerals obtained by adding E to the reference numerals in FIG.

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

The drawing borrowing request data input means 171 inputs predetermined data, at least data of a drawing number for specifying a drawing and data of a page and a terminal number for specifying a transfer destination. It consists of a program required to guide and monitor data input required for drawing borrowing applications. The drawing revision request means 172 sends a drawing revision request signal including the data input from the drawing borrowing request data input means to the registration terminal DE. The drawing change means 173 is for changing the 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 a change date, a change reason, a change content, a change symbol, a name or a signature of a changer. The revision numbering requesting means 175 sends a revision numbering command for requesting the revision drawing to be given a revision drawing number to the management terminal EE. The command includes a registration drawing number and a terminal of the design terminal. And numbers.
The drawing number replacing means 176 rewrites the drawing number of the registered drawing borrowed from the registration terminal DE to the revised drawing number received from the management terminal EE after the request for renumbering.
The data editing means 113E is provided with the data editing means 11 described above.
Similarly to FIG. 3, image data is constructed by adding the revised drawing number and the change history data inputted from the change history data input means 174 to the graphic data revised by the drawing modifying means 173. The registration request unit 114E requests the registration terminal DE to register the data edited by the data editing unit.

Further, as in the case of the above-described registration terminal, the registration terminal DE stores the data read-out registration means 115E and the graphic data of the drafted drawing and the revised drawing based on the specific drawing number or the 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 figure number storage file 116E, a revised figure number assigning means 120E, a revised figure number sending means 121E, and a registration means 122E.

The figure number storage file 116E stores, as in FIG. 11, a figure number that is continuous for each of the registered drawings, for each layer division. Revision drawing number assigning means 120
E compares the figure number included in the revised numbering command received from the design terminal AE with the registered figure number, and continuously sets and outputs the revised figure number attached to the figure number. .
The revised figure number sending means 121E transfers the revised figure number given from the revised figure number giving means 120E to the design terminal AE. The registration means 122E sequentially registers the revised figure numbers given by the revised figure number giving means 120E in the figure number storage file 116E.

In the case of revising a registered drawing with the above configuration, first, the command “borrow drawing” in the menu shown on the right side of the display screen 34 in FIG. 9 of the drawing terminal A is executed. On the basis of this, the CPU of the design terminal
8, the revision program is executed as shown in the flowchart, and in the first step S51, the data of the drawing borrowing application form as shown in FIG. Items displayed on the display unit of the terminal A and required for drawing borrowing application, for example, the figure number and the number of pages for specifying the registered drawing to be borrowed, the borrowing date,
The user is requested to input a department for recording the borrower, a name, and a terminal number for specifying the transfer destination of the graphic data.
When required data is input from the drawing borrowing request data input means 171 of the design terminal AE, the data is given to the registration terminal DE as drawing borrowing request data by the drawing revision requesting means 172, and the drawing data is lent from the registration terminal. Wait (S52).

In the meantime, the registration terminal DE communicates with the design terminal AE
Calls the drawing specified by the drawing borrowing request data received from the drawing storage file and transfers it to the design terminal AE specified by the terminal number. In this case, the fact that the drawing is being lent for change is recorded in the storage area of the lent drawing of the registration terminal, for example, by setting up a flag bit. When a drawing, quotation, reference, borrowing, or the like is requested from another CAD terminal and the host computer F with respect to the drawing in which the flag bit is activated, the drawing is being changed for the terminal. Report that Based on this, the terminal that has executed a command such as “borrow drawing” or “draw out” displays on the screen of the display unit that drawing out or lending cannot be performed because it is being changed. . Accordingly, the term "borrowing a drawing" in the claims refers to lending, drawing,
Used to include either citations or references.

The designer of the design terminal that has received the rental of the registered drawing applied from the registration terminal DE confirms whether or not the drawing is a borrowing application target drawing while viewing the drawing displayed on the display screen (S53). In the case of the drawing to be borrowed, the drawing change means 173 can arbitrarily change the displayed part drawing as it is (S5).
4).

When the change to the changed drawing (S54) is completed, the execution of the "end" command is followed by the management terminal E
From E, the data of the drawing change application form for recording the fact of the drawing change is quoted, a title column 343a and a change history column 343c are displayed in the parts diagram on the display screen of the design terminal,
The entry in the title section 343a and the entry of the changed article in the change history section 343c are requested (S55).

The processing of the change data is performed so that the designer can immediately check the change history on the drawing revision from the screen. That is, a change history column 343c is displayed on the right side of the title column 343a on the display screen. The change history column has a change frequency entry column, a change content entry column, a change reason entry column, a change date entry column, and a changer entry column. If you change the drawing,
A symbol having a numerical value of the number of changes, for example, a symbol in which the numerical value is surrounded by a triangle is displayed. When a plurality of changes are made by a single change, the same symbol is displayed at each changed portion, and the same symbol is automatically entered in the change frequency entry field. The figure before change and the figure after change are shown in the change content entry column. The change date entry field is populated with data from the calendar function of the day. Further, in the figure number display field after the change, a figure number obtained by combining a figure number of the cited drawing with a numeral indicating the number of changes with a hyphen is given by the automatic numbering function of the management terminal EE.

In the example shown in FIG. 14, the first change is 1
This shows that on August 30, 991, the figure of the original drawing of the drawing number B1001 in FIG. 9 was changed from a triangle to a square. On the second change, on August 31, 1991, the perfect circle of the figure was changed to an ellipse, and the figure number after the change was B1.
001-2. This change article,
A change symbol, a change content, a change reason, a change date, a sign, and the like are included. The entry of this changed article can be performed by a word processing function.

When the change history such as the change date, reason for change, change contents, change symbol, changer's name or signature is entered by the change history data input means 174, and the "end" command is executed, the change is made. The data of the drawing and the entry in the title box 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 the revision is completed by the input of the drawing change and the change history information, and subsequently, the “numbering” command is executed by the revision numbering requesting means 175 to automatically acquire the revised figure number. When the number is requested from the management terminal EE, in the management terminal EE, the revised drawing number assigning means 120E transmits the design terminal A
Number storage file 116E based on the figure number received from E
Check the registration status of the drawing number before change, set the revised drawing number,
In order to provide this to the drawing number sending means 121E and the registration means 122E, the drawing number sending means 121E sends the set revised drawing number to the design terminal AE, and the registration means 122E sends the revised drawing number. It is registered in the figure number storage file 116E (S58).

Finally, when the “end” command is executed,
The data editing means 113E adds the revised figure number to the graphic data of the changed drawing to form image data, and the revised figure number and change history information add to the attribute information to form character data. Registration request means
At 114E, it is registered in the drawing drawing storage file.
Then, by executing the "check request" command, the drawing drawing storage file is transferred to the unchecked drawing file of the check terminal B (S59).

When the “registration” command is executed instead of the “check request” command, the file is moved from the drawing drawing storage file of the design terminal to the registration terminal DE. Registered terminal D
At E, the data read / register means 115 E divides the data received from the design terminal into image data and character data, and changes them into a drawing drawing storage file 177 and a revised drawing storage file 178 which constitute a registered drawing storage file. It is stored in a predetermined area of the history storage file 179 (S5
9).

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