Obtain a list of rotation values of multiple geometry from a reference plane

Hi everybody,
as I wrote in the title, I need to obtain the rotation values of some plans that I constructud in grasshopper. I need to connect this values in Hummigbird, and bring the geometry that are oriented in the same direction of the plane into revit as a family.

I try to explain in a better way:

I have a curve that I divided with the component divide distance and than I created a plane for each of this point with the component Perpendicular Frame. In this way i have differents plans that correspond with the points.

I know that the plane YZ is the reference plane where the rotation value is 0.

How can obtain a list of rotation values in degree between the reference plane and the plane that is rotated?

I tried with the orient direction component, but it doesn’t have an output where extract this value.

Senza titolo-3

In blue are the reference plans with null rotation value and in green the plans that I need to obtain the rotation value.

Can someone help me?
Thanks in advance :slight_smile:
