Problems solved by technology

Existing technology cannot meet the requirements of each type of drawing, but the structure remains unchanged and only the size parameters of the drawing are simply modified. Using this method, a large number of engineering drawings can be quickly generated and the drawing efficiency can be improved.

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 It is the method flow chart of the present invention, and a kind of programmed drawing method of engineering drawing based on DXF format file of the present invention comprises the following specific implementation steps:

[0018] Select the engineering drawing of a typical structure, use CAXA drawing software to open it and save it as a .dxf file format, then reopen the engineering drawing of the DXF format file, and mark the position where the size parameter needs to be modified, such as the original size value "Φ100" modification It is "Mark 1", and so on. Use this method to mark the position where the parameter needs to be modified.

[0019] Modify and replace the marked drawing parameters, and retain other relevant parameters of the drawing. The process of changing the data of the parameters that need to be modifi...

Abstract

The invention relates to a DXF format file-based programmed drawing method of an engineering drawing, relating to all kinds of engineering technical fields of CAD engineering drawings. The method comprises the steps as follows: reading the content of a DXF format file; using markers to mark positions where dimension parameters need to be modified in the DXF format file; determining the dimension parameters of drawings which need to be modified newly and reading the marked DXF format file, corresponding the dimension parameters of the drawings which need to be modified newly at the marking places with the markers one by one and replacing as a dimension numerical value of a new drawing; and storing, recording and outputting the newly generated DXF format file. The method of the invention is a flexible, extended and universal method and could be used for fast generating the engineering drawing after extracting the DXF graphic file format. The method of the invention simplifies the tedious process of a mechanical drawing, is convenient for generating a lot of engineering drawings of which only the parameters need to be modified and improves the work efficiency.

Description

technical field [0001] The invention relates to the technical field of engineering drawing engineering, in particular to a programmed drawing method for engineering drawings based on DXF format files. Background technique [0002] Taking the centrifugal compressor as an example, our company produces more than 300 sets of blower fans every year. Compared with the specific compressor parts, their structure and function are similar, but the corresponding part size parameters are different. How to quickly and A large number of engineering drawings that only modify parameters are generated, so as to achieve the purpose of improving work efficiency. [0003] The DXF graphics file format is a simple graphics file format developed by AUTOCAD, which can be recognized and opened by various engineering drawing software. Using DXF format files as the carrier of graphics files has good versatility and ease of operation. [0004] The rotor of the centrifugal compressor is composed of mul...
