Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for converting Japanese data between CAD systems, and more particularly to an apparatus for converting Japanese character data having different notation formats between different CAD systems using the IGES format standard. The present invention relates to a Japanese data conversion processing device.

[0002]

2. Description of the Related Art Since a Japanese data conversion processing device is not added to a conventional data conversion system between CAD systems, IGES format standard drawing / geometry data generated by another CAD system is received, Although it is possible to convert the data into the original code of its own CAD system, if the Japanese data included in the data is written in different ways, data other than the IGES format standard is generated. Therefore, the exchange of Japanese character data in the CAD system is treated as a restriction item.

The points of difference in the notation method of Japanese data will be described below.

First, the notation method of Japanese data can be classified into a character code system and a character description system.

As a character code system, shift JIS,
JIS, JIS ward points, EUC, etc. are typical. As an example of different data depending on the character code system, for example, the hexadecimal code of the character "love" is shift JIS.
88A4, JIS 3026, JIS ward point 1
626, B0A6 in EUC.

As the character description system, there are a direct description of characters and a character code description as shown in the explanatory view of the character description system of FIG. 3, and regarding the method of character code description, a hexadecimal code is used. There are a method of describing with a comma (,) and the like, and a method of describing one character with a hexadecimal code fixed to four characters. The display of FIG. 3 shows a case where the direct description “Aidenden 1” is described as the actual description data.

In the character description, there are cases where Japanese and ASCII code characters of 2 bytes and 1 byte are mixed, and the description and notation method at this time are the same as Japanese and ASCII code characters of FIG. There are a plurality of types of display methods, as shown in the explanatory diagram for explaining the notation method when a mixture of symbols. The display of FIG. 4 shows a case where Japanese “Kanji” and ASCII code character “ANK” are described together with “Kanji ANK”. An example here is'<B4C1,BBFA> AN
It shows that the notation method such as K ',' [B4C1BBFA] ANK 'is different.

As described above, when the drawings and geometrical shape data are exchanged between CAD systems by using the data of the IGES format standard, the data generated in the same Japanese notation is correctly the drawing data of the CAD system. However, the data generated in different Japanese notation has a different character code and the corresponding characters cannot be correctly converted into drawing data of the CAD system, so there is a restriction item for the exchange of Japanese character data in the CAD system. I was dealing with it.

SUMMARY OF THE INVENTION Conventional CAD described above
In recent years, Japanese data conversion processing devices between systems have been
With the spread of the D system, the number of users who are considering the exchange of drawings in the CAD system that they already have is overwhelmingly higher than the users who are introducing CAD and are considering the exchange of drawings. In addition, users who introduce a new CAD system often consider exchanging drawings for upgrading from the old CAD system and for migrating drawings that are assets from the old CAD system up to that time. Considering this, the data generated by the same Japanese notation can be correctly converted into the drawing data of the CAD system, but the data generated by different Japanese notation has different character codes and the corresponding character is correctly the drawing data of the CAD system. Since it can not be converted to, it was treated as a restriction item about the exchange of Japanese character data in the CAD system, The thing, becomes very big constraint for the user, there is a problem that that could affect great deal to the introduction of the new CAD system.

An object of the present invention is to provide a Japanese data conversion processing device between CAD systems which can correctly convert data generated in different Japanese notations when data is converted between CAD systems.

[0011]

A Japanese data conversion processing device between CAD systems according to the present invention receives data of the IGES format standard generated by a plurality of types of CAD systems and receives a unique code of a specific CAD system. In a data conversion system for converting data, a Japanese notation conversion system for receiving a Japanese notation code used for each of the plurality of types of CAD systems and converting it to a Japanese notation code used for the specific CAD system The above data conversion is made up of a Japanese notation conversion instruction file that instructs whether to perform special character notation conversion, and a standard character code external character code conversion table that supports unique codes that do not support standard Japanese character codes. This is a configuration added to the system.
