The scanner 207 is a CCD (Charged Coup).
This is an image reading device used to convert data shown on a paper medium into electronic data using a led device or the like.

The hard disk 203 described above is
The following three databases (design book data DB2
03a, a three-dimensional design data DB 203b and a format data DB 203c).

The design book data DB 203a, which is a first database, stores design book data obtained as a result of digitizing the design book B as described later.

Here, the format data refers to information indicating how information on the design is represented in the design document. This format data is created in advance for each design document such as a list diagram and a frame diagram. For example, the format data for the list diagram is constituted by information indicating what is described in each frame in the list as shown in FIG.

Next, the operation of the design data providing system of the present invention will be described.

FIG. 5 is a flowchart showing a processing procedure of the design data creation system 2 accompanying creation of three-dimensional design data. The design data creation system 2 reads the design document B received from the customer C with the scanner 207 (S101), thereby obtaining a TIFF (Tagged Image File).
Format) image data. This image data is stored in the RAM 202.

Next, by performing raster / vector conversion on the image data stored in the RAM 202, design book data capable of distinguishing and recognizing figures, characters, numerical values, and the like is created (S102). The design book data is created in, for example, a DXF (Drawing Interchange File) format. Then, the design book data thus created is registered in the design book data DB 203a (S103).

Next, referring to the format data stored in the format data DB 203c,
It is determined what content is indicated in the design document data registered in a. Specifically, for example, referring to the format data for the list drawing, it is determined which information is shown in which frame in the list shown in the design document data. As a result, data (hereinafter referred to as attribute data) relating to attributes (dimensions, arrangement, connection state with other components, etc.) of each component of the building is acquired (S).
104).

By the way, as described above, various drawings are included in the design document, and the attribute data of the same component is shown in each of the plurality of drawings. Due to an error or the like, the attribute data of one component member may be different depending on the drawing. In such a case, it is determined which attribute data is correct by comparing the attribute data shown in each drawing with each other. Then, a correction process is performed on the design document data indicating attribute data having a value different from the attribute data determined to be correct so that the attribute data becomes correct (S105). If the attributes of the constituent members are the same in all the drawings, such correction processing is unnecessary, and it goes without saying that the process proceeds to step S106 without executing step S105.

Based on the attribute data of the constituent members obtained as described above and corrected as necessary, three-dimensional design data reflecting the dimensions, arrangement, joining state, etc. of each constituent member is created ( S106), the created three-dimensional design data is registered in the three-dimensional design data DB 203b (S1).
07). FIG. 6 shows an example of the three-dimensional design data thus registered.

In this plan view, the encircled symbols (X1, X2, etc.) are for specifying the wick, and are data acquired from the wick detailed diagram as described above. Also, the distance between the cores is represented as numerical data, but these numerical data are
It is obtained from the floor plan and the like described above.

By performing the same processing as the above-described processing, three-dimensional design data relating to a plan view, a front view, a side view, and the like showing the structure of the building is created.

The above-described attribute data is associated with each component in the drawing represented by such three-dimensional design data. Then, the three-dimensional design data can be easily corrected by changing the value of the attribute data. Therefore, the three-dimensional design data can be reused when a construction drawing is subsequently created. The correction processing will be described later.

The design data creation system 2 creates an e-mail with the three-dimensional design data registered in the three-dimensional design data DB 203b as attached data, and sends the e-mail to an e-mail address previously transmitted by the customer C. (S108). As a result, the customer C
The electronic mail can be received by using 1 or the like, and the three-dimensional design data attached to the electronic mail can be obtained.

It should be noted that instead of providing the three-dimensional design data to the customer C by using an e-mail, for example, H
TTP (HyperText Transfer Protocol) or FTP
Of course, it may be provided by performing data communication based on (FileTransfer Protocol) or the like.

When the customer C desires, the design data creation system 2 may transmit the three-dimensional design data to the design data analysis system 3. in this case,
The design data creation system 2 transmits the three-dimensional design data to the design data analysis system 3 via the dedicated line PN.

Next, the above-described correction processing will be described. FIG. 7 is a flowchart showing a processing procedure of the design data creation system 2 accompanying the correction of the three-dimensional design data. First, the operator causes the display 205 of the design data creation system 2 to display the three-dimensional design data to be corrected. Thereby, for example, three-dimensional design data as shown in FIG. 6 is displayed on the display 205. Here, the operator operates the input unit 204 to place a pointer (position on the display) on a component whose attribute information needs to be changed among the components of the building indicated in the three-dimensional design data. Is moved to indicate the mark.

The design data creation system 2 acquires the position information of the pointer moved by the operator (S
201). Then, based on the acquired position information, determine which component the pointer is pointing to,
The operator specifies a component whose attribute information is desired to be changed (S202).

The attribute data of the component members specified as described above is obtained by referring to the three-dimensional design data displayed on the display 205 (S20).
3). Then, the acquired attribute data is displayed using a window as shown in FIG. 8 (S204).

The window shown in FIG. 8 displays the attribute data of the column identified by the symbol C1. Such windows are provided for each component so that items necessary to represent the attribute data of each component can be displayed. The operator refers to the attribute data displayed on the window and selects a matter to be changed.
Then, new data is input for the selected item.

When the design data creation system 2 determines that the pointer has been moved by the operator operating the input unit 204 (YES in S205), the process ends. On the other hand, the pointer has not moved (N in S205).
O), when it is determined that the confirm button on the window shown in FIG. 8 is clicked (YES in S206), the attribute data is corrected based on the newly input data (S20).
7) The three-dimensional design data including the attribute data thus modified is registered in the three-dimensional design data DB 203b (S208). Thereby, the correction processing is completed.

The pointer has not moved (S20).
If it is determined that the decision button has not been clicked (NO in S206), the process waits until any of these events occurs by an input operation of the operator.

The customer C can acquire the three-dimensional design data by receiving the electronic mail transmitted from the design data creation system 2 using the PC 1 as described above. Then, when it becomes necessary to perform various analyzes on the building indicated in the three-dimensional design data, the customer C creates an e-mail using the PC 1 with the three-dimensional design data as attached data. In the body of the e-mail, type data indicating the type of analysis desired by the customer C (for example, output of integration, creation of a processing book, etc.) and an e-mail address serving as a destination of analysis data indicating the result of the analysis are input. ing.

FIG. 9 is a flow chart showing the processing procedure of the design data analysis system 3 when creating analysis data. The design data analysis system 3 receives the e-mail created as described above, and acquires three-dimensional design data that is attached data of the e-mail (S30).
1). Next, the type of analysis is specified with reference to the type data input in the body of the received e-mail (S30).
2).

As described above, since the three-dimensional design data includes attribute data of each component, various analysis processes can be executed by using the attribute data. Specifically, for example, in the case of integrating the skeleton area as the analysis processing, the surface area of each component is calculated. It is also possible to roughly estimate the cost required for the construction based on the frame area calculated as a result.

The design data analysis system 3 executes step S
According to the type specified in 302, analysis processing is performed based on the acquired three-dimensional design data, and analysis data indicating the result is created (S303). FIG. 10 and FIG. 11 show examples of the analysis data created in this way.

The analysis data shown in FIG. 10 shows the result when a processing book is created as an analysis process. Here, the processing book refers to a collection of data necessary for producing a formwork (temporary framework for driving concrete). Such a workbook can be easily obtained from the dimensional values of the constituent members. The analysis data in FIG.
The results in the case of integrating the frame area as the analysis processing are shown. As shown in FIG. 11, the result of this integration is represented by an integration table T compiled for each floor of the building.

The design data analysis system 3 stores the analysis data thus created in a storage device of the design data analysis system 3 (S304), and receives the e-mail with the analysis data as attached data. The e-mail address entered in the body of the e-mail is transmitted as a destination (S305).

The customer C can obtain the analysis data by receiving the electronic mail transmitted from the design data analysis system 3 using the PC 1 as described above.

When an electronic mail is transmitted from the design data creation system 2 to the design data analysis system 3 without passing through the customer C, not only the analysis data but also the three-dimensional design data is added in step S305. An e-mail with attached data will be sent. Thus, the customer C can acquire both the three-dimensional design data and the analysis data.

As described above, the present invention provides the customer C with the three-dimensional design data and the analysis data relating to the building. However, the present invention can also be applied to, for example, various industrial products in addition to the building. It is possible.
