If you know the triangle or can draw with tour known points, it then bisect each cusp and you get a center to trace a circle, hope this help.

Normally I use the perpendicular lines trick, and draw a circle tangent to those - my problem is that my circle isn't crossing at 90 degrees relative to the lines. Basically its a triangle, I have the circle intersecting near a corner, so the center point is somewhere below and to the side. I know the two points it will intersect the triangle at, and the radius of the arc between.

I think the command line version will work for me, I already know that I should be using it a lot more to simplify things, I just need to figure out the syntax and see if I can remember some of the math involved.

Thanks for the help, I'll try it out now!
