The sheet 1 is a general drawing sheet. For example, it is convenient to use a drawing paper provided with a drawing frame 2 as the base paper when CAD is used, and a blank paper when handwriting is used.

The drawing description frame 3 is a conceptual frame which is not described on the sheet 1. A set of external views representing a plurality of similar parts is created in this frame. The setting of the drawing description frame 3 is determined in relation to the drawing frame 2, the data frame 4, and the description frame 5 of the symbol representing the attribute. For example, when CAD is used, the drawing frame 2 corresponding to the size of the sheet 1 is set, and the size of the drawing description frame 3, the data frame 4, and the attribute symbol description frame 5 are individually set so that the drawing frame 2 fits within the drawing frame 2. Allocate to. The distribution of these sizes may be fixedly set according to the size and type of paper, or several kinds of different distributions may be prepared and may be set each time.

The data frame 4 is a column in which the component data of a plurality of similar components is written. The usage method is not fixed. For example, a basic drawing such as an external view is written in the drawing description frame 3, and differences between individual parts are described as partial views in the data frame 4. Very generally, it is represented as a list. One example is shown in FIG.

The attribute symbol description frame 5 is a column for describing a symbol representing an attribute of a plurality of similar parts and a set of external views described in the drawing description frame 3. The attribute symbol is one of classification symbols. The classification code is a combination of one or more classifications, and is classified based on one or more classification criteria such as dissimilar parts, types of assemblies, and types of materials.

In the embodiment shown in FIG. 1, an external view of a door is shown in a drawing frame 3. There are a plurality of types of doors, and each component is different in at least one item of width dimension W, height dimension H, and color tone. FIG. 2 shows a table of the drawing numbers of these parts and the data contents of each part.

An example of drawing a similar part drawing having the above-mentioned structure will be described below. An example of drawing using CAD will be described, but the CAD system used here is general. The CAD system example shown in FIG. 3 is a central processing unit (CPU).

The type of drawing, for example, plan view, side view, bottom view, sectional view, etc., is selected according to the type of parts to be described and similar or dissimilar parts. Numerical values and symbols shown on the external view are shown with fixed dimensions in common parts for all similar parts, and with symbols in different parts. After the drawing in step S11 is completed, the attribute symbol is added and input in step S12. After the above operation is completed in step S13, the input drawing data is stored in the drawing data storage area 41 of the HD 14 under the management of the attribute symbol in step S14.

Next, the procedure for registering the component data of similar components will be described with reference to the flowchart of FIG. Registration of part data is also performed using the same CAD system used for drawing. The part data includes numerical values, processing symbols, materials, etc. corresponding to individual parts of the symbols of the external view described in the above drawing. Precautionary notes / history items that do not appear on the drawing should be described in a remarks column. In order to easily identify these parts data for each part together with the part number, step S2
Enter 1 and enter. After inputting the component data, step S
In step 22, the attribute symbols to which the similar parts belong are added, and after these inputs are completed in step S23, the attribute symbols are managed in the component data storage area 42 of the HD 14 in step S23.
Store at 24.

The drawing order, the input order of the component data, the type of the input data, and the like are not limited to the above embodiment. That is, it is possible to display drawings having a plurality of types of attributes in parallel, to extract and list components that perform the same processing, and so on. It is also possible to display the sequences by matching the partial data or by the size. In addition, the component data may be input independently, or may be input while displaying the input drawings on the display 13.

The procedure for reading out the registered drawing data and component data and the printing procedure using the PR 15 will be described below with reference to the flowchart of FIG. The attribute symbol (or the part number including the attribute symbol) is input in step S31. Based on this input, the CPU 11 reads the drawing data and the component data from each storage area of the HD 14 in step S32. The read data is stored in the CPU 11
Are combined in step S33 and displayed on the display 13 in the form of the embodiment of FIG. 1 (step S34). Printing of the drawing displayed in step S34 is performed in step S
If it is determined in step 35 that printing is necessary, a print command is input to print out in step S36.
