pro/e 二次开发
应用背景俗话说，工欲善其事，必先利其器。虽然已经有很多书籍都介绍了如何配置 proe 的二次开发环境，笔者也曾经按照那些著作的方法配置过，但是，笔者始终都没有发现一个较为完善的配置方法，配置的环境总有一些警告，或者显得非常繁琐，因此，笔者在这里向大家推荐一种零警告，零错误的配置方案。关键技术pro/e野火2.0与VC++接口的二次开发程序，野火4.0与VS2005接口连接的二次开发程序，二次开发主要为菜单、对象基本操作、参数尺寸关系式、装配概述、UDF特征创建、工程图概要和数据库。

这个程序并不帮你翻译任何文字,仅仅只是提供一个专为翻译工作设计的 编辑器.使用它你可以一行行对照的翻译原文. 而当你在翻译过程中碰到了不 认识的新词,计算机能充当你的词典或笔记本的作用, 让你的翻译工作事半功 倍.当你在翻译某一行文字时,如果发现某个单词不认识,字典区便会显示出单 词的意思,而不需要你的任何按键.当你在字典区没有发现你要的单词时,证明 单词库里没有这个单词,需要你自己从别的途径查找,然后写到字典区内,程序 将马上把它记录在单词库中-this procedure does not help you to translate any text, merely provide a translation for the design editor. Using it you can control the lines of the original translation. But when you in the process of translation encountered did not know a new word, the computer can serve as your dictionary or laptop, so you translation multiplier. when you are in the translation of a text line, if found not understand a word, the dictionary will show that the district words mean, without the need for any of your button. When you zone in the dictionary found no words to you, not to prove the word Curry words, you need Search through other channels, and then wrote a dictionary region, procedures it will be immediately recorded in the word library
