Problem with Normal

Hello,

As you can see from my printscreen, I have a problem locating a circle in a generic path. When my curve start to be a freeform, I cannot control the normal and I don't know how to solve it.

Any suggestion?

Thank you!!!

Instead of creating circles using normals (which is rotationally undefined in 3D), you should create circles from Plane and Radius. The planes in this case can be created using the Perp Frames component, which create minimal rotational frames along curves.

Thank you David. Unfortunately, I'm trying to use Perp Frame component, but without success.
I'm using with Circle (Plane and Radius), with Circle CNR, but nothing changes.

If I use CNR connecting Segments of the Polyline as crv and t(of divide curve) to t (of Perp Frame), it doen't work as well. Or I have same circle that follows the curve, but with wrong rotation, or I have good rotation but the circle is not rotating along the main curvature of curve.

YES!!! Finally, I was using perp frame instead of multiple perp frames. Thanks a lot!!!!
