Conventionally, as such a pattern data processing method, C
It is widely used to draw printed circuit boards using AD (computer-aided design).

When drawing, drawing elements such as a circle, an arc, and a straight line are displayed on the screen, these various data are converted into a file, and the final drawing is made by a desired printout means. These drawing elements, their display positions, commands for creation contents, etc. are all specified from the keyboard.

For example, in printed board CAD, component pattern data is created and stored in a library for use in subsequent drawing creation. This facilitates the formation of a printed board based on a component pattern that is a graphic element.

By the way, in such a conventional pattern data processing method, the data stored in the library is only graphic data, and management data related thereto is not included. Therefore, from a manufacturing standpoint, various numerical data are actually required when creating drawings.

In order to respond to this, the standard bin coordinates of the part pattern that are to be taken into consideration during manufacturing, the area coordinates that need to be taken into account on the board, the land coordinates, etc., can be retrieved from the library by the manufacturing side program or the board side program. After taking it out, I would calculate numerical data based on it.

[Problem that the invention seeks to solve]

However, in such a conventional pattern data processing method, the graphic data itself must be retrieved from the library by a desired program and then converted into numerical data, which places a burden on the program that retrieves it. Furthermore, there is a problem in that it affects the high responsiveness normally required for CAD.
