"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"

  • Sorry for my slow response.  Trying to finish up work and get ready for CDNLive! Silicon Valley. 

    My script does much more than just add film records it adds custom title blocks, basic fabrication drawing stackup, etc. I have been slowly moving it into more of a SKILL based script but most of it is still ran inside of UNIX using small NAWK scripts with an UNIX Script front end.

    I did present a paper some time ago which is still relevant in a lot of sections and it may be helpful so you could see exactly what I do.

    I will start another thread on this topic. "Automating Artwork Film Record and Title Block Generation"

    Hope this helps,
