Kicad includes it own version of Python anycodings_kicad (Version 2.7.13 at time of writing for anycodings_kicad Kicad 5.1 but moving to python 3 anycodings_kicad shortly). You can access Kicad python anycodings_kicad via the Pcbnew python terminal Tools anycodings_kicad > Scripting console.,Import the kicad site-packages into the anycodings_kicad python environment you are using., Import the kicad site-packages into the anycodings_kicad python environment you are using. import sys sys.path.insert(0,"/Applications/Kicad/kicad.app/Contents/Frameworks/python/site-packages/") import pcbnew ,Run it using the inbuilt python 2.7 using either the scripting console or specifying the Kicad python version in the shebang line (you will have to search for this but, in macOS, for instance it is found in /Applications/Kicad/kicad.app/Contents/Frameworks/Python.framework/Versions/Current/bin/python)

For more information about creating new footprint wizards, see the Scripting section of the Advanced Topics chapter.,Test for parity between PCB and schematic: when enabled, the design rule checker will test for differences between the schematic and PCB in addition to testing the PCB design rules. This option has no effect when running the PCB editor in standalone mode.,The tool adds the footprint for each symbol to the board and transfers updated schematic information to the board. In particular, the board’s net connections are updated to match the schematic.,Center view on cross-probed items: When both Eeschema and Pcbnew are running, controls whether clicking a component or pin in Eeschema will center the Pcbnew view on the corresponding footprint or pad.
