It is a figure which shows the structure of another Example of this invention.

In the figure, 1 to 8, A and B indicate those corresponding to FIG. CAD database, 27 and 31 are parts information data.
22 is a drawing data extraction unit, 23 is a parts information determination unit, 24 is a parts data creation unit, 25 is a product name data creation unit, 26 is a writing unit, 28 is a product name table, 32 is a parts list data extraction unit, 33 is a A character string creation section, 34 a coordinate information provision section, 35 a graphic data extraction section, 36 a drawing creation section,

In FIG. 2, a parts information processing device 9 creates parts list data from drawing data created by the CAD processing device 2 or drawing data created by the CAD processing device and stored in a CAD database, and generates parts information. data base 7
The parts list data is stored in the . In addition, the parts list data of the parts list created by the parts list creation processing device 6 or the parts list data created by the parts list creation processing device 6 and stored in the parts information database 7 is sent to the CAD processing device 2.
This completes the drawing data in addition to the drawing data (graphic data) created in the CAD data base 3 and stored in the CAD database 3.

FIG. 3 shows an example of the internal structure of each database file. The CAD database 3 has an internal data structure 1° as shown in FIG. 3(a).
When the data is output from the CAD system using a plotter or the like, it takes the format shown in the output image 11. The internal data structure 1° records the figure number indicating the ID (identifier) registered in the CAD database 3 and the character data sequence indicating the name, and furthermore, the LINE%CI
R.C.L.

Graphic element identification information such as N0TE, coordinates, size (radius, etc.), character data arrangement, and other data are recorded.

Among them, N0TE indicates character data such as parts information and title block information. Therefore, when graphic data such as LINE and CIROLE and character data N0TE are outputted at specified coordinates and sizes by, for example, a plotter, a drawing of an output image 11 is obtained. Furthermore, the parts information database 7 has an internal data structure 12 as shown in FIG. The format is shown in . Its internal data structure 12
As described above with respect to the CAD database 3, the figure number and character data arrangement are recorded, and item number data, quantity data, specification data, product name data, etc. are also recorded. Therefore, when each item number, quantity, specification, and product name are output by a printer, the output image is 1.
3 parts list is obtained.

Drawing data, that is, internal data structure 10 shown in FIG. 3(a) to internal data structure 12 shown in FIG. 3(b)
FIG. 4 shows the configuration of an embodiment of the present invention of a parts information processing device for creating parts list data. In FIG. 4, the drawing data extraction section 22 extracts the internal data structure 100 drawing data (figure cross) shown in FIG. 3(a) from the CAD database 21, and the parts information determination section 23 Character data (NGIE) is further extracted from the generated drawing data, coordinates are determined and character arrangement is determined, and the data is divided into parts information data and title block data. The coordinates of the area in the title block are, for example, figure number 50.
0.0<X coordinate(600,0io, o<y coordinate(30,
0 Name 500.0(X coordinate(600,030,0(Y coordinate(50,0) is determined for each drawing, so it is stored as 6 table'" or "program internal data" and N0
Determine the coordinates of TE. N0TE located at coordinates other than the title column data above, the character sequence of N0TE is the character "l"
(bar) and 1′” within 6 characters from the first character.
(bar) is blank (because the item number is within 4 digits), the second 1
N0TE that satisfies the condition that there is a character other than N l u after ``'' (bar) is extracted as parts information data.

The component information data extracted by the component information determining section 23 is then classified by the component number, number, unit, and component specifications in the component data creation section 24. Note that the graphic function of the CAD system has a function to display a mouth when there are two 1''s in the N0TE character sequence, by connecting the two 1''s with two horizontal lines at the top and bottom. This is used to represent the item number in the list. For example, if the data is 1101,
Only one mouth is displayed. Therefore, there are various variations in the representation of parts information data.

(1) 1 mouth 20 (M)-C21'0-0000-
0001(2) 1 mouth 2O-C210-0000-
0001(3) 1 mouth C21O-0000-000
1 For such things, the classification criterion is that A, the characters surrounded by the first °°1' and the next "1" are list item numbers ((1), (2), (3) are all 10 is the list item number) B,
If the character after the second "1" is a number, then "I IT (hyphen) is the quantity (20 of (1), (2) is the quantity) C0 quantity is followed by ゛ (if there is a ``, the next IT) Up to n is the unit (M in (1) is the unit) D. From the first ``-'' (hyphen) to the end is the part specification (C21O-0000-0001 in (1) and (2) is the part specification) E. If the character after the second 1" (bar) is an alphabetic character, the last part is the part specification ((3)
0210-0000-0001 is the part specification) In this case, the quantity is always 1.

F. If the unit is omitted, enter a blank (meaning use default value) in the unit (in the case of (2) and (3)).The product name data creation unit 25 refers to the product name table 28 and creates the part data. This is to create product name data that corresponds to the specifications.

The writing unit 2G checks consistency with the parts information database 27 using the drawing number as a key, and writes data according to the parts information database format, that is, the internal data structure 12 shown in FIG. 3(b). The program instructs you to write.

Note that the drawing/data extraction unit 22 may extract drawing data created by a CAD processing device.

Parts list data, that is, internal data structure 12 shown in FIG. 3(b) to internal data structure 10 shown in FIG. 3(a)
FIG. 5 shows a configuration of another embodiment of the present invention of a parts information processing device for creating drawing data of. In FIG. 5, the parts list data extraction unit 32 extracts parts information data and
It extracts the parts list data of the base 31, and the character string creation section 33 creates a character string in the format to be written in a CAD drawing (a drawing as shown in the output image 11 in FIG. 3(a)). The character string N0TE is created using the data extracted by the parts list data extraction unit 32 using an algorithm that is the reverse of the algorithm described above for the parts data creation unit 24. The coordinate information adding unit 34 adds coordinate data to each of the character strings created by the character string creating unit 33, and there are two possible methods for doing so. One is to write the part information N0TE outside the surrounding frame at equal pitches and CAD
One method is for the operator to rearrange the N0TE in the appropriate position during the drafting work.The other method is to write a note with only the item number in advance on the drawing side where the N0TE is written, or,
This is a method in which an attribute is given to an element (for example, a point) indicating a position, and when the graphic data extraction unit 35 extracts the graphic data, the position information given above is extracted and given to the N0TE. The figure data extraction unit 35 extracts CAD data and
The graphic data is extracted from the base 38, the drawing creation unit 36 superimposes a character string on the graphic data extracted from the CAD database 38, and the writing unit 37 generates a new superimposed graphic data and character string. CA drawing data
D. Writes to the database 38.

Note that the coordinate data given by the coordinate information providing unit 34 may specify, for example, that component data is displayed in a table format in the margin of the drawing of the output image 11, and such drawing data is In this case, the display may be changed to a leader line display as shown in the output image IIK of FIG. 3(a) by giving the coordinate position of each part data to be displayed as a leader line.
