CAM導入gerber file時的出現的警示

諸位大俠:
小弟在有cam350 v9.0導入由AD6.8輸出的GERBER檔時,總是不停地出現如下的提示,幾乎每層都有這樣的提示.還請諸位幫忙釋疑啊,先謝謝了.

Cannot convert the following lines in file"C:\DOCUMENTS AND SETTINGS\ \桌面\GERBER\BD11537-01A-G.apr":

Line 37: Error Creating Aperture:  Width must be greater than 0.

 for Dcode 46.

D46  RECTANGULAR         0.000       9.842       0.000 FLASH       0.000

Line 43: Error Creating Aperture:  Width must be greater than 0.

 for Dcode 52.

D52  RECTANGULAR         0.000      78.740       0.000 FLASH       0.000

没有附件,

提示是说D码的宽为0,看是不是应该把着两个D码改为square
