Jon I've managed to build PCBNew and figure I should be able to incorporate PCB renumbering into the source. I cannot figure out how to access the code documentation: I end up on dead links whenever I try and its kid of hard given the fact that most searches lead to user documentation. I would like and work with the developers to add renumbering to V6. I realize I will have to rewrite a significant portion of the code but the "hard part" should be able to stay the same. If you can help get me started I would appreciate it. There are some things I will need to understand with respect to the general direction of file formats, etc., so as not to waste too much effort. In the meantime I am trying to track down one last bug and will put my code into line with the KiCad coding standards. Thanks in advance, Brian -----Original Message----- From:
