Abstract

The present invention provides a CAD apparatus having high plotting efficiency, a symbol creation device facilitating symbol creation, a CAD program storage medium storing a CAD program incorporated into a computer to enable the computer to operate as the CAD apparatus, and a symbol creation program storage medium storing a symbol creation program incorporated into a computer to enable the computer to operate as the symbol creation device. There are provided a symbol data reading section that acquires table data (symbol data) representing a list describing attributes of each pin of an electronic part having plural pins, and a symbol creation section that applies each symbol pin having the same attribute as each attribute described in the list represented by table data acquired by the table data acquirement section to a part symbol representing the electronic part in arrangements corresponding to a described position of the attribute in the list.

Claims

1. A CAD apparatus having a plotting function of creating a drawing by arranging a part symbol at a position according to an operation, and a symbol creation function of creating the part symbol, comprising:

a table data acquirement section that acquires table data representing a list describing the attributes of each pin of an electronic part having plural pins; and

a symbol pin arrangement section that applies each symbol pin, which has the same attribute as each attribute described in the list represented by the table data acquired by the table data acquirement section, to a part symbol representing the electronic part in an arrangement corresponding to a described position of the attribute in the list.

2. The CAD apparatus according to claim 1, wherein the symbol pin arrangement section treats a blank column in the list as a position where the symbol pin does not exist.

3. A symbol creation device that creates a part symbol to be used with a CAD apparatus that creates a drawing by arranging a part symbol at a position according to an operation, comprising:

a table data acquirement section that acquires table data representing a list describing the attributes of each pin of an electronic part having plural pins; and

a symbol pin arrangement section that applies each symbol pin, which has the same attribute as each attribute described in the list represented by the table data acquired by the table data acquirement section, to a part symbol representing the electronic part in an arrangement corresponding to a described position of the attribute in the list.

4. A CAD program storage medium storing a CAD program incorporated into a computer to enable the computer to operate as a CAD apparatus having a plotting function of creating a drawing by arranging a part symbol at a position according to an operation, and a symbol creation function of creating the part symbol, the program constructing on the computer comprising:

a table data acquirement section that acquires table data representing a list describing the attributes of each pin of an electronic part having plural pins; and

a symbol pin arrangement section that applies each symbol pin, which has the same attribute as each attribute described in the list represented by the table data acquired by the table data acquirement section, to a part symbol representing the electronic part in an arrangement corresponding to a described position of the attribute in the list.

5. A symbol creation program storage medium storing a symbol creation program incorporated into a computer to enable the computer to operate as a symbol creation device that creates a part symbol to be used with a CAD apparatus that creates a drawing by arranging the part symbol at a position according to an operation, the program constructing on the computer comprising:

a table data acquirement section that acquires table data representing a list describing the attributes of each pin of an electronic part having plural pins; and

a symbol pin arrangement section that applies each symbol pin, which has the same attribute as each attribute described in the list represented by the table data acquired by the table data acquirement section, to a part symbol representing the electronic part in an arrangement corresponding to a described position of the attribute in the list.
