allegro如何实现库更新到PCB?
通过tool下拉的菜单可以更新pad文件,通过修改与更新到设计PCB可以轻松更改库。
但是如果想修改的是dra库文件,如何更新到设计PCB中去?(不要那种删除了所有的元件再添加的那种,要直接更新)
使用palac下拉的那个更新symbols...貌似不起任何作用,是操作问题还是设置问题?

看了这2个,按操作还是不对
确保路径准确无误;勾选被修改了的封装,忽略fixed属性;查看log
pad psm路径都设置了
因为删除了这个元件后,再手动添加就可以加入更新封装后的元件
奇怪的是如果不删如果正确设置来更正修正后的库?
单独更新焊盘是没问题的
就是更新元件库会出现这个奇怪的问题
也按照百度搜索的结果 看了一下 不知道可能还有啥地方会影响这个

請問是否設置了多個路徑,有時多個路徑也會引起這個問題。
我有碰到过这种情况,同一个板子,同一个零件库,16.3(没装补丁)也是更件无效,但是删掉零件再放下来OK,用16.5的更新没问题。
没有设置多路径
看来只能是原理图与封装完全一致的情况下 更新不会出错
