Embodiment 1 FIG.
FIG. 1 is a configuration diagram of a CAD application system and a drawing management system according to Embodiment 1 of the present invention. 1, a drawing management system server 1 (first server), a CAD application system drawing server 2 (second server), and n client terminals 3-1, 3-2,. n is connected to the IP network 4. A storage device (not shown) composed of a hard disk or the like of the drawing management system server 1 contains a drawing management system program 50 that is a drawing management means for maintaining CAD drawings, and changes in the master part file group 20. A change reflection program 70 which is a change reflection means for reflecting the existing component files 21 to 25 and the environment file 10 to other drawings, the environment file 10, and a master component file group 20 including a plurality of component files 21 to 25; Change history storage means for storing drawing A (reference numeral 30A) and drawing B (reference numeral 30B), which are CAD drawing files generated in the environment information storage format, and part files 21 to 25 that have been changed and the file names of the environment files. The change history file 60 is stored. The database 5 of the CAD application system drawing server 2 stores the same drawing A (reference numeral 30A) and drawing B (reference numeral 30B) as those stored on the drawing management system server 1. The client terminals 3-1 to 3-n store a CAD application system program 40 which is a download means for downloading and using the drawings stored in the database 5 of the CAD application system drawing server 2. Yes.

  Next, operations of the CAD application system and the drawing management system according to Embodiment 1 of the present invention will be described. In FIG. 1, when the drawing A (reference 30A) and the drawing B (reference 30B) are used on the client terminals 3-1 to 3-n, the respective CAD application system programs 40 are stored in the database of the CAD application system drawing server 2. The drawing data (drawing A (reference 30A) and drawing B (reference 30B)) stored in FIG. 5 is downloaded from the CAD application system drawing server 2 to the client terminals 3-1 to 3-n and used. The client terminals 3-1 to 3-n do not have environment files and component files as in the prior art, and the CAD application system program 40 can use the drawings by downloading only the drawing data.

  Here, a case where correction occurs in the drawing data will be described. For example, when a correction occurs in the drawing A (reference numeral 30A), the drawing management system program 50 of the drawing management system server 1 is used to display and correct the drawing A (reference numeral 30A). The drawing management system program 50 takes out the CAD drawing A (reference numeral 31A) of the drawing A (reference numeral 30A), refers to the environment file 10 on the drawing management system server 1, and reads the master part file group 20, The CAD drawing A (reference numeral 31A) is displayed. For example, in the modification of CAD drawing A (reference numeral 31A), when a new part file 25 is newly created and used for CAD drawing A (reference numeral 31A), the drawing management system program 50 is stored when saving the updated drawing data. The CAD drawing A (reference numeral 31A), the environment file 10, and the necessary part files (for example, the part files 21, 24, 25) are compressed into one file, and the drawing A (reference numeral 31A) is generated. And stored in the drawing management system server 1. The generated drawing A (reference numeral 31A) is stored in the database 5 of the CAD application system server 2 and can be used by the client terminals 3-1 to 3-n. In this way, by introducing the drawing management system program 50 that generates drawing data in the environment information storage format and constructing the CAD application system, each client terminal 3-1 to It is possible to always use the latest drawing data without distributing environment files and component files to 3-n. The present invention can be applied not only to new addition of a part file but also to modification of a part file and addition / change of the environment file 10, and the same effect can be obtained in this case.

  In addition, when a change occurs in the part file (for example, described below as the part file 21) of the master part file group 20 or the environment file 10 in the modification of the drawing A (reference numeral 30A), the part file 21 is used. It is necessary to reflect the changed contents in other drawing data on the existing drawing management system server 1. In this case, after the modification of the drawing A (reference numeral 30A) is completed, the operator describes the name of the part file or environment file in which the change has occurred in the change history file 60 and saves it. Thereafter, by executing the change reflection program 70 on the drawing management system server 1, the change reflection program 70 refers to the change history file 60, and from all the drawing data stored on the drawing management system server 1, Search / extract the file that has been changed, that is, the drawing that includes the component file 21. If there is a drawing including the changed part file 21, the changed part file 21 is acquired, the drawing data is regenerated in the environment information storage format, and saved in the drawing management system server 1. At the same time, it is stored in the database 5 of the CAD application system drawing server 2. As a result, it is possible to reflect the changed contents in all the drawings without performing the work of distributing the changed part file 21 to the client terminals 3-1 to 3-n. The effect which can reduce this time is acquired. Note that the change reflection program 70 may start the reflection process in response to an instruction input from the operator, or may start the reflection process when the change history file 60 is updated.

  As described above, in the present embodiment, even in a large-scale CAD application system, CAD drawing change management is performed by the drawing management system server, and changed drawing data (including environmental files and component files) is stored. Since it is stored in the database 5 of the drawing management system server 1 and the CAD application system drawing server 2, it is not necessary to distribute the difference file to hundreds to thousands of client terminals. A normal CAD drawing becomes available. In addition, when a change or new addition is made to an environment file or a part file of one drawing data, the change reflection program 70 describes the name of the part file or the environment file in which the change has occurred in another change drawing. Since the change is reflected in the data, it is not necessary to distribute the difference file to each client terminal, and the latest and normal CAD drawing can always be used on the client terminal. Furthermore, since the change history is centrally managed by the drawing management system server 1, it is possible to easily increase the number of client terminals, and the burden on the maintenance work of the system administrator can be reduced. In addition, since the CAD drawing format is the environment information storage format, the necessary part files and environment files are downloaded along with the drawing data at the time of download, so that the drawing data can be used immediately. In addition, it is possible to save the trouble of storing environment files and component files in advance in each client terminal, and the display speed of CAD drawings can be improved (shortened).

Embodiment 2. FIG.
In the present embodiment, maintenance of the drawing data, which has been performed using the drawing management system program 50 (FIG. 1) on the drawing management system server 1 in the first embodiment, is performed on each of the client terminals 3-1- The configuration is implemented with n. As shown in FIG. 2, in the present embodiment, CAD drawings are displayed on the client terminals 3-1 to 3-n by using drawing data environment files and component files 21 to 25, and the CAD drawings. Stored is a terminal drawing management system program 51 which is a drawing management means for making changes. The other configurations are the same as those in FIG. 1, and thus the description thereof is omitted here.

  In the configuration of FIG. 2, when drawing maintenance is performed, the terminal drawing management system program 51 on each of the client terminals 3-1 to 3-n is executed. Drawing data to be corrected (for example, drawing A (30A)) is downloaded from the database 5 of the CAD application system drawing server 2 to the client terminals 3-1 to 3-n. The terminal drawing management system program 51 extracts the CAD drawing A (31A) from the downloaded drawing A (30A), and sends the environment file 10 and the part files 21 to 25 of the master part file group 20 via the IP network 4. Are read from the drawing management system server 1 and the CAD drawing A (reference numeral 31A) is displayed. Alternatively, the environment file 10 and the component files 21 to 25 of the master component file group 20 included in the drawing A (reference numeral 30A) may be used. Here, when additions / changes occur in the part files 21 to 25 and the environment file 10, the contents of the change are automatically updated by the master part file group 20 on the drawing management system server 1 and the drawing management system program 51 for the terminal. It is reflected in the environment file 10. When the maintenance of the CAD drawing A (reference number 31A) is completed, the terminal drawing management system program 51 loads the latest environmental information storage format drawing file (drawing A (reference number 30A) on the client terminals 3-1 to 3-n. ) And the drawing A (reference numeral 30A) is stored in the database 5 of the drawing management system server 1 and the CAD application system drawing server 2.

  As described above, according to the present embodiment, the same effects as those of the first embodiment can be obtained, and by storing the terminal drawing management system program 51 in the client terminal, drawing maintenance can be performed by any client. The effect that it can implement on a terminal is acquired.

  As shown in FIG. 1, a drawing management system program 50 is also stored in the drawing management system server 1, and drawing maintenance is performed by both the drawing management system server 1 and the client terminals 3-1 to 3-n. In the configuration that can be implemented from the above, maintenance may be performed by switching appropriately.

Embodiment 3 FIG.
As shown in FIG. 3, in the present embodiment, a change content automatic extraction program 80 is added to the drawing management system server 1 with respect to the configuration of the second embodiment, and the part file of the master part file group 20 is changed. The change history file 60 for storing the history is automatically created. In the first and second embodiments, when a change occurs in the part file of the master part file group 20, the operator registers the file name of the part file of the master part file group 20 in which the change has occurred in the change history file 60. Was. However, when a person (operator) is involved, there is a possibility that an input error or an input omission may occur in the file name registered in the change history file 60. A case may occur that is not accurately reflected in other drawings. In order to prevent such a human error, in the present embodiment, the storage method of the part file of the master part file group 20 on the drawing management system server 1 is improved, and the change history file 60 is automatically generated. The configuration is as follows.

  Therefore, in the configuration of FIG. 3, an automatic change content extraction program 80 is stored in the drawing management system server 1. The change content automatic extraction program 80 is a program for extracting the name of the changed component file and storing it in the change history file 60. FIG. 4 shows the inside of the drawing management system server 1. The master part file group 20 is divided into a new part file storage area 20A and an existing part file storage area 20B. The names of the existing component files created so far are stored in the existing component file storage area 20B, and the names of the component files corrected by the client terminals 3-1 to 3-n are stored in the new component file storage area 20A. It is assumed that it is stored.

  Next, the operation of the third embodiment will be described with reference to FIG. It is assumed that the drawing is corrected at the client terminal 3-1, and the part file 21 is corrected and saved therein (steps F01 to F03). The corrected component file 21 is stored in the new component file storage area 20A of the master component file group 20 of the drawing management system server 1 (step F04). Next, the client terminal 3-1 starts the change automatic extraction program 80 on the drawing management system server 1 in order to reflect the corrected component file 21 in other drawings (step F 05). Then, the change content automatic extraction program 80 on the drawing management system server 1 refers to the content of the new part file storage area 20A and writes the name of the corrected part file in the change history file 60 (step F06). Next, the client terminal 3-1 starts the change reflection program 70 on the drawing management system server 1 (step F07). The change reflection program 70 refers to the contents of the new part file storage area 20A of the change history file 60, searches for the presence or absence of other drawing data in which the changed part file 21 is used, and extracts the drawing to be changed. (Step F08). If there is a change target drawing, the changed part file 21 is used to regenerate the target drawing as an environment information storage format file, and the database 5 in the drawing management system server 1 and the CAD application system drawing server 2 (Steps F10 to F12). Next, the drawing management system server 1 moves the part file 21 stored in the new part file storage area 20A to the existing part file storage area 20B and clears the contents of the change history file 60 (steps F13 to F13). F14). If there is no change target drawing in step F09, the process skips to step F13 and executes the processes of steps F13 and F14.

  As described above, according to this embodiment, the same effects as those of the first embodiment can be obtained, and the contents registered in the change history file 60 can be automatically extracted by the change contents automatic extraction program 80. By doing so, it becomes possible to prevent a mistake in registering the changed part file name by a person, and the contents of the part file can be reliably reflected in other drawings.

Embodiment 4 FIG.
FIG. 6 shows the configuration of the third embodiment in which the change contents of the component files 21 to 25 in the master part file group 20 are reflected, that is, the change contents automatic extraction program 80 and the change reflection program 70 are executed. (First and second timer means) are improved so as to be executed at regular intervals.

  In the above-described third embodiment, the change content automatic extraction program 80 and the change reflection program 70 are executed by an operator who has modified the drawing on the client terminals 3-1 to 3-n. Although a mistake such as forgetting to execute the automatic change content extraction program 80 and the change reflection program 70 due to the presence of a person (operator) can be considered, in Embodiment 4, the change content of the master part file group 20 is reflected. By implementing it automatically, it is possible to more reliably reflect changes.

  Next, the operation of the fourth embodiment will be described. The part files 21 to 25 of the master part file group 20 corrected by the client terminal are stored in the new part file storage area 20A of the drawing management system server 1. In the drawing management system server 1, a timer program 90 is operating, and the change content automatic extraction program 80 and the change reflection program 70 are executed at regular intervals. As described above, the reflection of the changed part files 21 to 25 of the master part file group 20 to the other drawings is managed by the timer program 90 and executed at a constant period, thereby preventing reflection by the operator.

  As described above, in the present embodiment, the same effect as that of the third embodiment is obtained, and in addition, the timer program 90 is operating in the drawing management system server 1, and the content of the change is periodically repeated. By executing the automatic extraction program 80 and the change reflection program 70 and automatically applying the changed component files 21 to 25 to the other drawings at regular intervals, it is possible to prevent the reflection from being reflected by the operator. There is an effect.

  It should be noted that the execution timings of the change content automatic extraction program 80 and the change reflection program 70 may be the same, but of course, they may not be the same, and which execution is to be performed first may be determined as appropriate. .
