# How to print gerber files? (mac)

I'm currently using circuits.io to create a very simple circuit. However, before ordering the board, I would like to print it in order to see if it's the right size and/or the elements fit in my own designed footprints.

Since circuit.io only lets you download gerber files, is there a simple way to print those gerber files? Maybe if someone can point me to the spec for the gerber files I could craft a simple script to convert the file to something that I could actually print.

gerbv - A Free/Open Source Gerber Viewer, part of gplEDA, does what you want. Specifically it is at http://gerbv.geda-project.org/.

• thanks, I'll try that... as soon as I can compile it :S the macports version is not compiling right now, and I haven't found a binary version – funkaster Nov 7 '12 at 22:13
• ok, I completely wiped out macports and installed fink... that did the trick! thanks :) – funkaster Nov 7 '12 at 23:24
• just an update: I removed fink and I'm now with homebrew, that seems more updated and it worked right out of the box. – funkaster Nov 13 '12 at 20:38

gerbv is available for OS X. It can print to PDF or PostScript.

With Homebrew installed, type in your terminal:

brew install gerbv

let it install then type:

gerbv

and it will open
