Abstract

PURPOSE:To realize the efficiency of design operation by changing the operation of a CAD system only by giving an operation characteristic parameter as the change instruction of a system initial value without correcting the source program of the CAD system. CONSTITUTION:System initial value change instruction 1-1 is registered in a change source form system initial value file 1-3 by using a text editor means 1-2. Then, a system initial value register means 1-5 updates an internal form system initial value file 1-6 based on the contents of a basic source form system initial value file 1-4 and the file 1-3. Next, a system main body initialization means 1-9 reads out data from the file 1-6 to be set in a system operation set value table 1-10 concentrately managing the CAD operation characteristic parameter. CAD function means 1-11a to 1-11c read the contents of the table 1-10, and performs the change of the operation corresponding to the value.

Used to store 6.

Next, the operation will be explained.

In FIG. 1, the method for changing the CAD operating characteristics is to send a system initial value change instruction 1-1 in a source format of the programming language C using a text editor means 1-2, and send the changed amount to a system initial value file 1 in source format. -3 starts with registration.

System initial value change instruction 1-1 does not require specifying all parameters that define CAD operating characteristics.
The user only needs to write what they wish to change.

Modifiable CAD operating characteristic parameters express operating characteristics using relatively simple numerical values, character strings, etc. The target is what you can do. The parameters are written using the C language variable assignment format; for example, in the case of numerical values) cmna24. kmnmod=1 ; or in the case of a string, use 5trcpy (ctc
a03. hcmsz, "36P"): is used.

The modified source format system initial value file 1-3 is U
It is built on the NIX file system and stores only those CAD operating characteristic parameters that the user has instructed to change in a format similar to a programming language source program. Changes source format system initial value file 1
The text editor means 1-2 is used to newly register, modify, and delete the contents of -3 in the same way as when modifying a programming language source program.

When the registration of the changed source format system initial value file 1-3 is completed, the system initial value registration means 1-5
A modified portion of the internal format system initial value file 1-6 is generated from the contents of the basic source format system initial value file 1-4 and the modified source format system initial value file 1-3.

The basic source format system initial value files 1-4 are CA
This is a part of a source program in which all the D operating characteristic parameters are coded using C language structures. System initial value registration step 1-5 combines the basic source format system initial value file 1-4, which is part of a program written in C language, and the modified source format system initial value file 1-3 into one file. A complete C language source program is created (step 2-1 in FIG. 2). This program has a function of modifying a portion of the internal format system initial value file 1-6 specified by the user. Furthermore, the system initial value registration means 1-5 compiles this program (step 2-2), links it to create an executable file (step 2-3), and executes this to create an internal system initial value file 1. -6 is updated (step 2-4). This step consists of an executable file for combining files, a C language compile command, and a link command.

In order to check how some or all of the system initial values have been modified, use the system initial value list output means 1-7 to read data from the internal format system initial value file 1-6. , outputs the system initial value list 1-8.

After the registration of the internal format system initial value file 1-6 is completed, the system main body initialization means 1-9 reads data from the internal format system initial value file 1-6 and performs CAD processing.
It is set in the system operation default value table 1-10, which centrally manages the operation characteristic parameters. This table is divided according to the purpose of use: system general management table, screen display management table, command
-s ” 7-PULL, WORK, DF-D command・
It consists of tables, CURV, 5PLN command tables, etc.

The CAD function means 1-11a to 1-11c are called by the system operation mode and the user's command selection instruction, and are based on the system operation default value table 1-11c.
Read the contents of 10 and change the operation corresponding to the value. For example, in the case of dimension line generation, various things are changed, such as the dimension line, line type, line width, the length of the extension line, the radius of the black circle at the end point, and the length and height of the arrow.

In addition, the system operating default values can be changed by commands operated by the user while the CAD system is running, and the operating characteristics can be changed not only when the CAD system is started, but also at any time during execution. be able to.

〔Effect of the invention〕

As explained above, the present invention enables the CAD system to be used without modifying the source program of the CAD system, by simply giving operating characteristic parameters as instructions to change the system initial values.
By being able to change the operation of the AD system, CAD users have the effect of being able to improve the efficiency of their design work by themselves without receiving assistance from a programming engineer.

Furthermore, it is possible to shorten the working time for changing the CAD operating characteristics, and it is possible to prevent the reliability of the CAD system from decreasing due to changes.
