Creating arcs in pcbnew python

Layout
1

I am struggling with the documentation for the pcbnew python scripting console. I am trying to draw an edge cut arc.

I can’t find any examples, the closest I have found is in the interface code, something like this:

**** I worked out the problem and have added the offending line

arc = pcbnew.DRAWSEGMENT(board )
arc.SetShape(pcbnew.S_ARC)
arc.SetCenter(pcbnew.wxPoint(pcbnew.FromMM(centre[0]),pcbnew.FromMM(centre[1])))
arc.SetArcStart(pcbnew.wxPoint(
pcbnew.FromMM(centre[0]+math.sqrt(outerRad**2-(fingerWidth/2)**2)),
pcbnew.FromMM(centre[1]+fingerWidth/2)))
arc.SetAngle(totalAngle)
arc.SetLayer(edgecut)
board.Add(arc)

Am I approaching this all wrong? Are there any examples I have missed?
thanks
Dave

It turns out I was being daft, I failed to add the arc to the canvas with a
board.add(arc)

I will amend it above.

One other thing that confused me is that the angle is measured in tenths of a degree.

A good way to learn how objects are represented is to draw them in pcbnew and then inspect the result from python api. Then you can replicate it from api.
