I'm trying to create an arc, in a 3d sketch, but noticed that the following:

value = instance.CreateArc(XC, YC, Zc, X1, Y1, Z1, X2, Y2, Z2, Direction)

"create arc(center, beginning point, end point, direction)"

is only good in 2d sketches.

If I have a 3d sketch open, is there an api command for creating arcs that would work in a 3d sketch.
