DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CAD for building and the like.
The present invention relates to a system for delivering drawing data.

[0002]

2. Description of the Related Art Conventionally, various attempts have been made to reuse created CAD drawings for architectural use. This is to improve the efficiency by reusing CAD drawings so that similar drawings are not newly created many times. However, in practice, it is difficult to reuse CAD drawings even within the same company. This is one of the reasons that the reuse of architectural CAD drawings is prevented, for example, due to the fact that CAD drawings for architectural use are not standardized and various types of drawings are created. In particular, individual design offices are not re-used because there are few reusable drawings.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a system capable of distributing CAD drawings for building or the like in a form that is easy to reuse by using the Internet or the like. .

In order to achieve the above object, the present invention has a database based on CAD drawings divided into layers, and allows the terminal to specify settings for each layer. In transmitting a CAD drawing from the database to a terminal, the CAD drawing distribution system performs conversion by setting for each layer. The setting designation for each layer can be registered for each user, and the user does not need to designate the CAD drawing setting for each download from the terminal. Further, the CAD drawing may include a layer in which information such as an advertisement related to the drawing is described.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating a system configuration according to an embodiment of the present invention. According to the present invention, a database 112 of architectural CAD drawings is constructed in a server 110 connected to the Internet. For this database 112, the user can use the terminals 132, 1
The user accesses from a location 34 to obtain a desired architectural CAD drawing. In the present system, when architectural CAD drawings are stored in the database 112, the CAD drawings are subdivided into layers as much as possible, the names of the layers and colors to be displayed are standardized, and the drawings are classified for each drawing. Is building. How each user connects to the server 110 from each of the terminals 132 and 134 to obtain a desired CAD drawing will be described in detail with reference to FIGS. FIG.
From 34, the system is accessed and the desired CAD
It shows a screen transition diagram for obtaining a drawing. This will be described below mainly with reference to FIG.

In FIG. 2, when accessing the system, first, a screen for inputting the member ID and password is displayed (S102), and the member ID and password are input. When the correct ID and password are input, the user can log in to this system, and the main menu screen is displayed (S104). When "drawing drawing" is selected to obtain a CAD drawing, a menu screen for obtaining a CAD drawing is displayed (S105). Menus of a system that can obtain this CAD screen include "drawing search", "drawing conversion setting", "basket content display", "service description", and the like.

When "service description" is selected, the CA
The explanation screen of the system that can obtain the D drawing is displayed (S
108), a table of contents for explanation of this system is displayed. When you select an item in the table of contents, a description of each item is displayed. For example, when the item "buy drawings" is selected, an explanation screen for this is displayed (S118). In this screen, when "purchase price sample table" is clicked, a sample drawing is displayed and a purchase price is also displayed (S120).

When a drawing search is designated on the menu screen (S105), a drawing search screen is displayed (S106). On this screen, for example, a list of classification items such as a part name, a building element, etc., for searching the database of the architectural CAD screen is displayed. When a desired item is checked out of the classification items and a "search execution" button is clicked, a search result display screen is displayed (S114). On this search result display screen, the CA
A list of D drawings is displayed. When the CAD screen is designated on this screen and the "Details" button is clicked, the designated drawing is displayed (S116). Look at the drawing in the search result, and if it is the desired drawing, click “Add to Basket” to put it in the basket for downloading.

After all the desired drawings have been searched and placed in the basket, when a "basket content display" button on the menu screen (S105) is clicked, a screen displaying the contents of the basket is displayed (S112). Here, the drawing can be displayed by clicking the "Details" button (S116). Alternatively, by specifying a drawing and then clicking "Delete from Basket", the drawing in the basket can be deleted. To download the drawing in the basket to the terminal, click the “Download” button.

Now, in order to convert the setting in the drawing of the search result into a desired setting, before downloading,
On the menu screen (S105), select “Drawing conversion setting”.
Select Thereby, the drawing converged setting screen is displayed (S110). This will be described with reference to the converged setting screen 300 shown in FIG. First, the drawing data stored in the database 112 will be described.
As described above, the drawing data is subdivided into each layer and stored in the database 112. This layer includes a character layer (MOJI) on which characters are written,
Dimension layer of dimension line (SUNPO), concrete layer where concrete structure is written (CO
N), a concrete section hatch layer (CON-H) in which a concrete section hatch is written, a steel section (STEEL) or a steel section hatch (STEEL-) in which an iron section or a hatch of the section is written.
H). The names (in parentheses above) and colors to be displayed are set as standard for each layer of the above-described screen, and when these are downloaded, they can be changed to those set on this setting screen. . By setting the same layer name, layers can be combined.

The setting in FIG. 3 starts with the selection of the file format. This is done by specifying the radio button in front of each file format under "Please select the file format of the drawing to download."
Now, in order to change the layer name and the display color of the CAD drawing stored in the database, it is necessary to specify a desired layer name and display color for each layer in FIG. 3 ( 312). FIG. 4 shows a specific example of this designation. In the drawing in the database shown in FIG. 4A, the display color of the layer having the layer name “MOJI” is “C
As shown in FIG. 4B, the display color of “YAN” (blue) becomes “RED” (red) with the layer name “layer” as shown in FIG. It is shown that. (Because colors cannot be displayed in the drawings, they cannot be distinguished in both FIGS. 4A and 4B.)

Also, a layer is assigned to each line type, and by assigning another line type to this layer, the line type can be changed. The layer for each line type includes, for example, a center line layer (TYUUSEN),
Fine line layer (HOSOSEN), extra fine line (GOKUHO)
SO), a dashed line layer (HASEN), a fine dashed line layer (TENSEN), a dash-dot line layer (1TEN), a two-dot chain line layer (2TEN), and a point layer (TEN). Note that the names in parentheses above are standard names, and in the example shown in FIG. 3, the line type cannot be changed for the middle line, thin line, extra fine line, and point. FIG. 5 shows a specific example of the change of the line type. FIG. 5 is an example in which the line type is set and the line type is changed in the layer setting 310 of FIG. That is, a broken line (fine)
Layer line type is DOTTE.
D2 (dashed line (fine)) to CENTER (dash-dot line)
(See 314). FIG. 5 (a)
Shows standard drawings stored in the database. FIGS. 5A and 5A show the line types of the TENSEN layer, as indicated by an enlarged portion 422, and FIG.
In (2), the line type of the dotted layer is a broken line (42).
4). FIG. 5B shows a diagram set on the setting screen (see 314) in FIG. 3 and downloaded from this system. As shown by an enlarged portion 426 in FIG. 5B (1), the line is changed to a dashed line, and in FIG. 5B (2), the line type is also changed in that layer (see 428). It is shown that.

Further, the font of the character in the character layer and the dimension layer can be set. This is "Please set the character style" on the screen 300 in FIG.
By designating each character layer or dimension layer in 320, it is possible to set the standard font Roman or exfont for half-width characters and full-width characters to a desired font. FIG. 6 shows an example in which the character font is changed. FIG. 6A shows, as standard, drawings in the database, romans for a font for half-width characters (shx font) and ext for a font for full-width characters.
An example in which font is specified is shown. FIG. 6 (a)
FIG. 6A shows a display example, and FIGS. 6A and 6B show designation in a layer (see 432). This is specified in FIG.
20), it is changed after downloading, as shown in FIG. 6 (b). 6 (b) and (1) are display examples, and FIGS. 6 (b) and (2) are font specification examples in layers (half-width is italic: italic, full-width is bigfont)
(See 434).

The character strings used in the drawings can also be changed. In FIG. 3, the process is performed by designating “target character string” and “replacement character string” in a field 330 below “replace character string”. FIG. 3 shows an example in which “stretch” is converted to “stretch” and “polystyrene” is converted to “vinyl”. This is specifically shown in FIG. FIG. 7A is a drawing in the database, and FIG. 7B is a drawing downloaded after setting as shown in FIG. The character strings “expandable pin” 442 and “polystyrene foam” 4 in FIG.
After the download, as shown in FIG. 7B, “expansion / contraction pin” 446 and “vinyl foam” 448 are displayed.
Has been converted to.

By the way, the designation of the conversion set in FIG. 3 can be registered as a my layer (My layer) by a button 340 for a character string and by a button 350 for other designations. This registration is performed corresponding to the member ID. Therefore, if no change is required at the time of the next login, there is no need to specify again, and the specification registered here converts the drawing to be downloaded. The registered settings can be called up with the “Call My Layer” button 370 and corrected. In addition, it is also possible to return all the set items to the standard mode by using a “return to standard layer” button 360.
Is possible. Also, a scale can be set (see 380).

Returning to the screen transition diagram of FIG. 2, as described above,
After specifying the conversion as required, click the "Download" button (S112). When the download is performed, a confirmation screen is displayed (S122), and the specified converted CAD screen is stored in the terminal. Can be.

The above-mentioned CAD drawing may include a layer describing related information such as an advertisement and a catalog. This is because, when a desired CAD drawing is transmitted to a user, information such as an advertisement or a catalog related to the drawing is selected from an information database such as an advertisement, and a specific layer is applied to the drawing to be transmitted. This can be realized by adding and transmitting. The layer of the related information such as the advertisement and the catalog is designated so as not to be visible when the CAD drawing including this layer is transmitted. The user who has obtained the CAD drawing including the related information such as the advertisement and the catalog can view the related information by designating only the layer of the related information such as the catalog when desired. The related information such as advertisements and catalogs can be added to each CAD drawing as a specific layer when stored in the database.

As described above, the present invention can retrieve a large number of drawings, select a desired drawing, convert the drawing into a desired setting, and obtain the desired setting. Therefore, the present invention can be easily reused. The configuration of the present invention can be realized on a server by reading out the program from the storage medium storing the program related to the present invention by the system and executing it. The recording medium includes a floppy (registered trademark) disk, a CD-ROM, a magnetic tape, a ROM cassette, and the like.
