I have to make a sqare hole in the PCB for a project. The square 16mmx16mm hole should be located where the Copper fill blocker is located for illustration purpose only… The hole should not have copper boder.

I have read a few topics where users explain how to do it with Inkscape, cnc or laser…

The Inkscape look interesting, but, a bit complex for me. If anybody have a simple way to acheive it in fritzing please. The goal is to order a bunch of these (50+) already drilled. Thanks, Eric

Yes this is a little tricky. You need to add a cutout to the sketch using this svg:

outline

and getting the format of it is a little difficult. Since I have done this before I made the svg above (to download a copy of it right click on the image above and select save image as.) It is installed in this sketch

like this

then click the load image file icon and supply the location of the saved svg file. That should produce a message like this

press OK and it will load the image. That produces this gerber output (here displayed in gerbv)

The hole is set by the contour.gm1 file like this

I think this is pretty close to what you wanted, if not you need to edit the svg in Inkscape or another svg editor and change the paths (in both boardoutline and silkscreen!) to move the hole where you need it. Hope this helps!
