Abstract

PURPOSE:To construct the drawing retrieval method adapted to an operation by a user. CONSTITUTION:A retrieval data generating means 6 receives an instruction for generating drawing data, generates the drawing data from the drawing data registered in advance and attribute data of the kind determined in advance of a drawing component registered in advance, stores it in a drawing data base 10 through a storage means 1, and also, stores the drawing component in a retrieval data base 11 through the storage means 1 as a parts table related to the drawing name of the drawing and the attribute data. A retrieving means 7 receives a retrieval data base retrieval instruction, retrieves the retrieval data base 11 by an algorithm determined in advance, based on the attribute data given by this retrieval instruction, and displays the retrieved parts table on a display device 9 through a display means 8.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing search method for efficiently searching drawings from additional information such as design information and production information added to graphic data in a computer-based design and drafting support system.

0002

2. Description of the Related Art Conventionally, this type of drawing search method searches for drawings in a database storing drawing data using the drawing name, creator name, creation date, update date, etc. as keys.

0003

[Problem to be Solved by the Invention] In the conventional drawing search method described above, it is impossible to completely match design information such as component names and production information such as product codes with drawing names. The drawback is that it requires re-verification of the drawn drawings on a visual display device.

[0004] Furthermore, even if the user takes his own means for managing and searching drawings, it is difficult to maintain consistency with the drawing database, making maintenance difficult.

[0005]

[Means for Solving the Problems] The first invention is a drawing search method in a design and drafting support system using a computer system, which includes a drawing database and a search database, and which registers data in advance in response to drawing data creation instructions. Drawing data is created from the graphic data and predetermined types of attribute data of drawing components registered in advance, and is stored in the drawing database via a storage means provided in advance, and the drawing data is a search data creation means for storing the component in the search database via the storage means as a parts list in which constituent elements are associated with the drawing name of the drawing and the attribute data; a search means for searching the search database according to a predetermined algorithm based on the attribute data given by and displaying the searched parts list on a display device provided in advance via a display means. be done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the entire drawing search method in the design and drafting support system of the present invention. In a computer-based design/drafting support system, a method for adding design information and production information to graphic data and their aggregates is a method for incorporating design/production information as attribute data. A separate patent application has been filed under the name (Patent Application Hei 01-1
10251).

The present invention is a method for efficiently searching a drawing database storing a plurality of drawing data by using attribute data of this method. Step 1 (S1) to Step 3 (S3) are the flow of processing in the present invention.

In step 1 (S1), attribute IDs and attribute tables necessary for drawing search are defined and registered in the attribute information file 4 using the storage means 1. Step 2 (S2) is a step for creating drawing data, and first step 21 (S2) is a step for creating drawing data.
In step 21), graphic data consisting of various basic graphic information is registered via the graphic data registration means 5 (the registration file is not shown), and then in step 22 (S22), the attribute data registration means 3 registers the graphic data that is registered in step 1. The attribute information is read from the attribute information file 4 using the reading means 2 and the attribute data is registered (the registration file is not shown).
Finally, in step 23 (S23), the drawing data completed from the graphic data and attribute data registered by the search data creation means 6 is registered in the drawing database 10 using the storage means 1, and at the same time, using the storage means 1. Search data consisting of a drawing name, component parts, and attribute data is registered in the search database 11. Step 3 (S3) is
After registering multiple drawings in the drawing database, search means 7
The search data is read from the search database 11 via the reading means 5, and a necessary drawing is searched based on one or more search condition keys input from the visual display device 9. In the figure, the area surrounded by dotted lines is the area for which the above-mentioned patent has been applied.

Next, an embodiment of the present invention will be explained using FIGS. 2 to 5. A feature of the present invention is that the user can search for necessary drawings using search items and search tables that can be set arbitrarily. Attribute I when searching for
D. This is an example of defining an attribute table. There are no particular restrictions on the number and order of attribute IDs constituting one attribute table and the number of attribute tables set for drawing search. Figure 3 shows step 2
This is an example of the drawing data created in (S2), and the drawing name:
The drawing data of K-001 includes graphic data including graphic information aggregates G1 and G2, and graphic information aggregates G1 and G.
It consists of attribute data for 2. As shown in the example of attribute data for G2, it is not necessary to register attribute data corresponding to all attribute IDs that make up the attribute table.

FIG. 4 illustrates means for creating search data from attribute ID information, attribute table information, and attribute data. The search data has a tabular data structure as shown in the figure, but the table name in this case is the same as the attribute table name defined in FIG. 2, and is "Parts List." When creating search data, search to see if a table name equal to the attribute table name exists in the search database, and if it does not exist,
Define the format of the table, that is, the name, type, and length of each item. In this table, in order to search the drawing database, the first item is automatically defined as item name: drawing name, type: alphanumeric characters/kana, length: 20 bytes, and the second and subsequent items are in the attribute table. It is defined according to the sequence of attribute IDs, the data type, data length, and item name of each attribute ID. Once the format of the table is determined, only the attribute data is extracted from the drawing data, and each attribute data is registered in the table according to the arrangement of the attribute table. If a table with the same name as the attribute table name exists in the search database, the table definition process is not performed and each attribute data is added to the existing table.

FIG. 5 is a diagram illustrating a search of a search database using parts information as a search condition key. During a search operation, search table items and a search condition input field are displayed on the visual display device, and when a search condition is specified in the condition input field, data strings that match the conditions are displayed on the visual display device.
You can obtain the necessary drawing information. In this example, the input conditions are that the third item 'D' is '1.0' and the eighth item 'D' is '1.0'.
A search is being performed for drawings that include parts with the item 'product code' being 'MAD'. As for the conditions to be given, in the case of character items, specification can be made using the entire string or partial string, and in the case of numeric type items, it is possible to specify specifications that are greater than or less than the specified number, greater than or equal to the specified number, less than or equal to the specified number.

[0013]

[Effects of the Invention] As explained above, the present invention enables drawing searches that suit the user's operations by creating a drawing search database using attribute IDs, attribute tables, and attribute data that can be set arbitrarily by the user. A system can be constructed.
