Filling Zones (copper pours) inside the Python API

[arikrupnik]

I’m writing a Python script to generate gerbers, drill files, BOM and position file from a layout. It’s similar in function to [1] but generates additional types of files for PCBA. In his comments for [1], John mentions he doesn’t know how to fill zones through the Python API. According to [2], this was impossible in 2015.

[3] teaches us how to get a list of zones in a board (zone=board.GetArea(idx)), but not how to fill them.

Is it possible to fill zones inside the Python API in 2019?

The forum tells me that new users can put at most two links in a post, so here’s the missing link for [3]: https://github.com/KiCad/kicad-source-mirror/blob/master/pcbnew/python/examples/listPcb.py

import pcbnew
board = pcbnew.GetBoard()
filler = pcbnew.ZONE_FILLER(board)
zones = board.Zones()
filler.Fill(zones)

Seth, thank you! This works like a charm. I tried making a list of zones and passing that to ZONE_FILLER, but it would fail with a SWIG error. Thank you for giving the the right answer so quickly!

Ari.
