Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is an example of an electric wiring diagram used to explain a method of creating a required material quantity table by applying the present invention.

In FIG. 1, 1 is a distribution board, 2 and 3 are lighting equipment, 4
And 5 are figures showing the cables for the lighting fixtures 2 and 3, respectively, and 11, 21, 31, 41 and 51 are the above-mentioned figures, respectively, namely the distribution board 1, the lighting fixtures 2 and 3, and the lighting fixtures. Cables 4 and 5 (hereinafter referred to as figures 1, 2, 3, 4 and 5)
The definition data areas of 12, 22, 32, 42 and 52 are rectangular
It defines the shape definition data areas 11, 21, 31, 41 and 51.
These diagonals , 13, 23, 33, 43 and 53 are the definition data of the corresponding figures 1, 2, 3, 4 and 5 , respectively, 14, 24, 34, 44
And 54 are connection lines connecting the figures 1 to 5 to the corresponding definition data areas 11, 21, 31, 41 and 51 , respectively, 25, 35, 45.
And 55 are figures 2 to 5 and their corresponding definitions.
This is a common leader line indicating the correspondence with the definition data areas 21, 31, 41, and 51 . Figure 1 shows the distribution board 1 and its definition data.
The leader line indicating the correspondence with the area 11 is not displayed.

First, figures 1 , 2 , 3 , 4 and 5 or their
CAD data required to display symbols by the usual method
To make these figures 1, 2, 3, 4 and 5 [step (a)]. Next, figure 1, 2, 3, 4 and 5
Definition data areas 11, 21, corresponding to each
Enter the area data that defines 31, 41, 51, and display
You. In the preferred embodiment, a rectangular
To set the area, the diagonal data of those rectangles
Input, display a rectangular frame, and define data areas 11 and 2
1, 31, 41 and 51 [Step (b)]. At this time,
Although not a component of the invention, common leaders 25, 35, 45,
Enter necessary data into CAD to display 55 at desired position
Force to display these leader lines . Next, desired definition data 13, 23, 33, 43, and 53 are input to these definition data areas 11, 21, 31, 41, and 51 , respectively, and defined.
The meaning data is displayed [step (c)]. Continued
Data for displaying the connection lines 14, 24, 34, 44 and 54,
That is, figures 1, 2, 3, 4 and 5 in the drawing and their definition data
Line data connecting the data areas 11, 21, 31, 41 and 51.
And connect these lines 14, 24, 34, 44 and 54 as desired.
Is displayed as a hidden line [step d]. This connection line
Described in the figure data and definition area of the figure
The defined data correspond to the
A quantity table can be created. And finally, the connection line
Combination of associated graphic data and definition data
Of figures 1, 2, 3, 4 and 5 shown in the drawing
Calculate or extract the required quantity of required materials for each,
These are integrated by product name and specifications, and are shown in Table 1.
A required material quantity table is created (step e). Here, the definition data areas 11, 21, 31, 41, and 51 are defined.
Their diagonals 12, 22, 32, 42 and 52, and their connection lines
14, 24, 34, 44 and 54 are hidden lines, that is, they can be displayed on the display as needed, but are preferably unprinted hidden lines when making a hard copy of the drawing. Also, the connecting wires 24, 34, 44 and 54 are connected to the conventional lead wires 25, 3
5, 45 and 55 can be used together. By doing the above, for example, the length of the cable is immediately known from the data input to the CAD, so it is possible to automatically process these CAD data and easily create the following Table 1 [Step (e)]. However, the related data such as the unit price is recorded in advance in the memory of the computer. Further, in Table 1, what is entered in the Name column C
Names of figures 1, 2, 3, 4 and 5 entered in AD, which are called from the computer's memory. What is entered in the specification column are definition data, the diagonal 12 and a
Since the relationship with the corresponding graphic is known by the connection line 14, the diagonal line 42, the connection line 44, and the like , those data can be immediately transcribed in the table.

[Table 1]

By processing the data in this table, an estimate of construction costs, an order for required materials, and the like can be easily created. The same operations as those described above can be widely applied to interior drawings of buildings, arrangement diagrams, piping diagrams , and the like.
Also, in the assembly drawings of various machines, the quantity of required parts
Is the same as above if it is shown in the drawing or definition data
To create a required parts list.

[0009]

As described above, according to the present invention, it is easy to associate a figure in a drawing created by CAD with its definition data, and therefore, it is easy and automatic to calculate the quantity of required materials. You can do it.
