ECO TO PCB 封装丢失解法

问题如下：
1。我在库里建好PART TYPE，并把大体可用的PCB封装全加了进去。等到ECO TO PCB之后，PCB里的元件封装有的只有一个PCB封装，有的少我要用的，其它的都在。怎么样可以避免此类问题发生？
2。板子布完局之后发现少了封装或封装不对，然后修正了下PART TYPE，再进行ECO TO PCB，可是PCB板里的封装没有改变，怎么样可发修改到我要的封装？
3。我想问下PADS在读库时，是不是有读库优先级呀？

Part Type ADF4360-1 has the following gate pins that do not match to the Library part:
(16 14) (13 16) (20 17) (17 18) (18 19) (19 12) (23 13) (12 7) (14 24) (24 4)
(7 5) (4 20) (5 23) (9 2) (10 21) (2 15) (21 22) (22 11) (11 10) (8 9)
(3 8) (1 3) (15 1).
Non matching Part Type ADF4360-1 is used by the following parts:
U40.
出现这种问题如何解决？
高手帮下，谢谢！

把pcb封装存成另一个名，再把Edit part把原理图封装重新存成和pcb一样的parttype就行了

必须重新命名eco才能变

先谢谢了。
我想问下是改PART TYPE名吗？

为了避免出现这种问题，一般都是一个PCB对应一个parttype，这样比较不容易出错。

再请叫下，PCB在铺铜时，特殊形状的图形怎么绘呀？如带斜角的、R角的、有斜边的。

PCB里面的字体怎么改呀？有哪位高手指点下呀！谢谢。

这个怎么理解？哪位高手帮忙解说下。

怎么样才能改掉这些错误？
