PPS: If anybody is willing to program this script/program I would be very thankful and I guess some of the community members as well…[/quote]
Here you go, pretty crude but did work for me already.
Runs on Python 2.7.2 and goes into a xyz.kicad_pcb via text-editor (I have KiCAD BZR5978).
KiCAD_CopperArc.py on Github Gist
The script pproduces the segments for an arc with the following specs (can be adjusted in the script):
- Center = x 105.0 mm / y 105.0 mm
- Radius = 20 mm
- Sides = 36
- StartAngle = 45.0 degrees
- Angle = 135.0 degrees
- TrackWidth = 0.4 mm
- Layer = F_Cu
- Net = 0
KiCAD has got some mind of it’s own in regards to nets of stuff you add to a kicad_pcb file that’s not originally from KiCAD (been there, had lot’s of fun) - it needs some fiddling and determination until it works (I suggest to get a proper file with nets from eeschema and adding to that) and the new copper is accepted and stays on the net you gave it, but once you got it - it’s working 
PS: totally forgot, I naturally used that script for something else and pulled it out of something bigger… looking around you’ll notice it is able do a bit more than just drawing lines to form an arc if correctly adjusted. I’ve already used it for pretty complex outlines/millings/comments/coppertraces/etc… that were based on calculations.
