15.5如何创建flash？

和原来的不一样了，新建flash symbol的时候要选择package configuration desired，

随便选一个进去后，add->flash无法添加，提示如下，好像层设置不对，可是也找不到在什么地方设置，

谁给解答一下啊

我也有同樣的問題
FLASH無法存檔,設好格式後卻看不到
是否LICENSE不完整?

flash,可以存档的.

新建flash symbol的时候要选择 File -> New -> flash Symbol

进入后直接选 Add -> Flash

没问题啊~~~

解决了。做封装时不能使用程序包里的Allegro Package，直接使用Allegro PCB Editor,然后File->New，选择相应的封装类型即可，这样就有Etch这个Class了，如果直接用Allegro Package建封装的话没有Etch,而是Conductor，会提示找不到相应的Class

不错,顶一下！感谢小编！
