"Undefined Line Width" default to Zero in Film Record - Gerber still outputs without Error

mcatramb91

I just noticed something that I thought was a little strange.  I added an additional Artwork Film Record for a special fabrication drawing and forgot to modify the "Undefined Line Width" inside of the Film Record.  When I output the gerber it only reported warnings in the log file and not an error due to the missing aperture for the "0" Line.  Part of my post processing script is to generate PDF File of some of the output Gerber Files and to my surprise most of the data was missing from this one PDF file which is because there was not an aperture with a line width of "0" so it did not draw anything in the Gerber.  The message in the Photoplot.log was as follows:

WARNING: 0 width  line found at (559.250 8280.710)
         ... ignored!
Multiple 0 width  lines; all will be treated the same as the first.

Either way I figured I would post this to let folks know that may not be aware of it.  No sure if it would be considered a software bug because I guess I should be more careful and reviewed all the log files.  Wasn't a major deal for me because it was caught upon review of the PDF files that were generated in error.  All my artwork film records are normally generated by script which defines the line width so this was an isolated where I generated a new film record manually and forgot to change the "Undefined Line Width"

  • Mike,

    This is a good point. I also had experienced the same problem earlier and corrected it by setting the "Undefined Line Width" to the required valuer in film options. By the way, I would like to know how to create the artwork using scripts. I don't have much experience in scripting. It will be helpful if you can share a basic/example artwork script or direct me to how to create a script.

    Thanks in advance
