Line diagram part graph proofreading method

Abstract

A circuitry part graphics checking method is characterized in that providing pre-established the first part graphics data into a circuitry; then, acquire the second part graphics data in basic graphics exchange size files; a computer can compare the second part graphics data with the first part graphics data according to the same part number; if the first part graphics data does not comply with the second part graphics data, the invention can create modification information to relevant personnel for checking, so as to improve the efficiency of checking for part graphics data.

Description

technical field [0001] The invention relates to a graphic data proofreading method, in particular to a component graphic proofreading method of a circuit diagram. Background technique [0002] In the design process of printed circuit boards, the previous layout design is one of the most important tasks. The operation of using computer to draw printed circuit boards is mainly divided into two parts, one is the previous placement work, and the other is One is the following circuit layout work, which needs to use part graphic data in the cloth processing operation, and the part graphic data is established by the layout personnel according to the part specifications, but the types of part specifications are various and complex, so when the layout personnel When creating part graphic data, the created part graphic data may be incorrect due to human negligence, for example, inputting wrong part size values, and the error is often discovered and modified during the process of fabri...

[0002] In the design process of printed circuit boards, the previous layout design is one of the most important tasks. The operation of using computer to draw printed circuit boards is mainly divided into two parts, one is the previous placement work, and the other is One is the following circuit layout work, which needs to use part graphic data in the cloth processing operation, and the part graphic data is established by the layout personnel according to the part specifications, but the types of part specifications are various and complex, so when the layout personnel When creating part graphic data, the created part graphic data may be incorrect due to human negligence, for example, inputting wrong part size values, and the error is often discovered and modified during the process of fabric processing or circuit layout, sometimes Even errors are not found, which can affect the quality and efficiency of printed circuit board design

[0003] On the other hand, the mechanical structure personnel also create part graphics data, and the part graphics data created by the mechanical structure personnel is generally called the International Graphics Exchange Specification (IGES) file, and the part graphics in the same basic graphics exchange specification file The data may also be incorrect due to human error. At present, the layout personnel manually compares whether the part graphics data created by the layout personnel are correct according to the basic graphics exchange specification files provided by the mechanical structure personnel. When the graphic data of the parts are different, check the part graphic data for errors by viewing the part specifications, but this method will increase the error as the number of part graphic data increases, because omissions may occur
