On the results of structural analysis of 3d closed curves

I am a student, I am trying on structural analysis in 3d closed curves and would like to produce this as a pavilion.
What I would like to ask is to get the vector of rotation moment (Mx,My) at an arbitrary point after the structural analysis as a beam.
I assume I will use the “node forces” component, but I am not sure which of the outputs corresponds to that.
Based on the results, I am trying to get a vector that is a composite of Mx and My.
