请各位帮忙解决 急！

当我在执行artwork时会出现已下提示，导致无法正确导出gerber file

---- Photoplot outline rectangle not found ... using drawing extents

 Can't open parameter file ... using default values:

 ARTWORK Error reading apertures.

好象是要设定一个你要出的范围,但具体在哪儿设定我也忘了

你的Format要設2,5

  小數位愈小，光繪才能繪出愈細的地方

詳細的資料cadence官網的FAQ中有gerber設定的PDF

之前我的Fomat设定的是5，5 ，出现的错误信息为

---- Photoplot outline rectangle not found ... using drawing extents

  Can't open parameter file ... using default values:
     DEVICE-TYPE        GERBER6X00
     G-CODES            NO
     STATIONS-PER-WHEEL 24

  WARNING: database resolution exceeds the resolution of the
      output coordinates (see FORMAT in parameter file).

而我将Format 改为2，5，出现的错识信息是同样的，

可以告诉我cadence官方網的网址吗?我用googel 无法搜到 。
