求救 高手进来吧!Allegro16.0设计的PCB

我用16.0设计了一个PCB,错误都没有了,Performing DRC...No DRC errors detected.
我先出NC drill, 正常NCLegend generation successfull
Legend 1: MANUFACTURING/NCLEGEND-1-12 ... layers TOP to BOTTOM
There were 1 drill legends generated.
然后我出gerber,可是却出现问题了,提示 database has errors, artwork generated canceled. please run DB doctor,
我运行了DB doctor,报如下的错误,
DBDOCTOR of drawing ****************************************

我再运行dbdoctor ,就正常了,能出gerber了,但是我再先出nc drill,又会出现上面的问题,大家知道是啥问题吗?

你的DRC目录下隐藏了一些报错的，全部都勾上试试setup、userperference、drc
