I have a PDF called A basic intrduction to Cadence Orcad (Allegro) 16.2 PCB Designer.
I have been following that to help me learn this program, so far it has worked but when I make the artwork (gerber files) Fig.25 says the Board Outline is not included in the films. Why is that? the PDF doesn't give me a reason why.
Doesn't the PCB Manufacture need the outline to make the board?
The PCB software I use now is Orcad Layout 9.0 and I can make outlines for the Artwork (gerber files).
Any help is appreaciated...
It's related to your board outline being zero (0) in width or thickness. Under the aerwork settings there is a undefined line width. Specify a value here (I suggest 10 mils or 0.254mm). Remember to do this for each artwork. You will then see a thickness in your gerber data. Some people generate an artwork that just contains the board outline.
Thanks for the info, I'll give it a try and let you know...
Actually it's not needed. It's comfort food for them. There have been 1 or 2 specfic vendors I've used in the last 100 or so boards that asked for it as a cross-check. Outputting it on its own film is best. Just create a film, set up just the outline to display, match the film to the display and then set the line width for plotting for this layer. Voila!
I tried putting 10 mils in the undefined line width box for each artwork and I left everything else the way it was and it still didn't work.
Dennis. Can you please confirm that the board geometry / oultine class/subclass is included in the artwork film you are viiewing ?
