Hello,
a complete newbie here, please bear with me.

So I am trying to find the intersection points between two co-planar Sketchup circles.
defined by:
C1 = [center1], [normal], radius1
C2 = [center2], [normal], radius2

This is probably a bad solution but I've been trying to use the Geom::intersect_line_line for each pair of Edge components, somewhat like this:

T=C1.each{|j| C2.each {|k|Geom::intersect_line_line(j,k)}}

But i stumbled on another problem, which is, Geom::intersect_line_line only accepts Arrays(i'm trying to input Edge objects, also Edge arrays won't work).
And, whenever i use the .to_a method to any Edge object(including in the above code), this is what i get:
"(eval): warning: default `to_a' will be obsolete"

Can anyone tell me what I have to do to make the Geom::intersect_line_line to work with Edges? Also is there a simpler solution to this that I'm missing?
