Problem Offseting curve

Hey everybody, I am kinda new to ghp and I am having issues trying to offset this curve 5 more times to their normal vector, when I try to offset it it gives me these strange patterns since the plane of the offset its default to Xy, could somebody help me get the normal vector of the curve please?

you can use isPlanar (Curve → Analysis → Planar) to get if the curve is planar, and the plane on which the curve sits

but in this particular case the offset steps you use are too large, the curve will self-intersect, try to play with the slider:
