元件旋转任意角度出6x00格式的gerber，问题在最后

Allegro产生gerber时在“filmcontrol”标签中有如下选项：

图1

Aperture也可以选择“without rotation”与“with rotation”

比如PCB设计中有旋转非90度的元件，对于RS274X时不会有什么问题，如果在用6x00产生gerber，选择不正确就会出不出来gerber，

如果按照图1与图2的选择，则在产生gerber时就会报错

ERROR: No aperture for RECTANGLE - 40.00 X50.00 at (19929.69 7769.10) Rotation:  n! D, I& n! k* R
60.000

这样就会导出gerber，但是将gerber导入CAM350时看到下面的情形，焊盘并没有旋转！

如果勾选“Drawmissing pad apertures”，其它的不论怎么旋转都能正常导出，并且最后导入CAM350时的gerber也是OK的。

1、在“control film”里的“Use aperture rotation”与aperture里面的“without rotation”与“with rotation”旋转是否有关系？

2、在“control film”里的“Draw missing pad apertures”到底是什么含义？下面的解释有点太简单了：
