Ground fill alternative

Hi Joan, Great app, and it is lovely that it is free too. I was wondering if I could get some help? I am trying to automate (perhaps with scripts) or simplify editing my geometries created in FlatCAM. I have been trying to find the best way to ground fill my PCB boards (I would like to have a ground fill as I am working with radio frequencies). I designed the boards initially on Fritzing and then imported them into FlatCAM. I then created geometries for both sides of the board. What I was originally doing was using ground fill in Fritzing and then in FlatCAM removing the extra ground filled area so my CNC machine did not have to do so much work (e.g. not have to go over the same area twice). As you can imaging this took a lot (and I mean a lot) of editing of the geometries in FlatCAM. What I am going to try now on is not using the ground fill tool in Fritzing, but now just open up/cut and vias and pins that are "ground" so they are electrically in contact with the ground planes. I think this will speed things up. However, I would like to speed this up further by somehow automatic the opening/cutting of the vias and pins with a script or something similar. This would be great as sometimes you finish editing your geometries, create the gcode, go to run the file on your CNC machine, and realise that you have forgotten to edit one important pin/via and you have to start the editing process again from scratch. If you could just use a script to open up/cut all the pins and vias, that would save lots of time. Another way of doing the above, which I think would be a great addition to FlatCAM (if you would agree) would be to create a separate geometry which you would edit, place all of the objects you would like to use to cut out your main geometry (created from your Gerber file) and then use a "cutpath" of one geometry from another to create a new geometry. In essence, this would be the opposite of the "join geometries" function. Would be great to have this kind of function. Looking forward to your reply Irishcream P.S. Do you take donations for your app?
