以铝合金轮毂设计为例,对几种常用设计软件的文件格式进行了分析。利用不同文件格式的优点,探讨了不同格式文件间的互相转换。有效地避免了文件转换时可能产生的数据错误和丢失。打破了单个设计软件使用的局限性,充分利用各个软件的优势部分,使设计手段更加丰富,提高了设计效率。 Taking the design of aluminum alloy hub as an example, the paper analyzes the file formats of several commonly used design softwares. The advantages of using different file formats to explore the conversion between different formats files. Effectively avoid the file conversion may result in data errors and lost. Breaking the limitations of the use of a single design software, make full use of the advantages of each part of the software to enrich the design means and improve the design efficiency.
