发现Altium布线规则的bug
本帖最后由 碧云天书 于 2014-5-3 18:23 编辑我已经把短路容限调到0了，还没法通过规则检测:Q

后来发现，把自定义的Classes全部删除就好了。
检查发现只要在规则里面使用了Classes自定义的类，甚至是在规则的Width里使用自定义的类，就会发生这个错误。
估计Altium觉得什么地方错了，但又没有这个错误的提示能力，就想当然地认为是第一项规则发生冲突，于是Clearance规则躺枪。:dizzy:
昨天赶工的时候，自动布线直接**，没有任何错误提示。:dizzy:
Message栏的信息是：

AD的速度真快，不到1秒的时间就决定什么都不干了。
今天偶然发现规则里面过孔的两个参数有误，过孔的铜边直径与机械孔直径设反了，孔比铜边还大。把两个数字倒一下，就可以自动布线了。
Altium的错误检查和提示环节有待提高呀！ 一般不用自动布线 涨见识了！ 支持一下~~~~ 比较少用自动布线，那样美观问题还有会有点问题 理论上的0是不存在的，每个软件的标准不一样，AD的貌似是0.01mil
