Re: Arc of a circle questions

In Kicad an arc is defined by Center point X and Y, Radius, Start and
End angles in 10ths of a degree and Start and End points X and Y.

This is overkill since the polar representation fully defines the Arc
and the Cartesian start and end
points are redundant.

Hi John-

This adjustment is already planned. I have a preference for start, end and radius. This allows radius to be positive for a clockwise arc and negative for a counter-clockwise one. It also makes the coding easier although this is secondary.

Some discussion of this was in the comments of the new symbol file format[1].
