i am not sure if what i would say is right 

but i thought you need to decompose SDLines and decompose and reconstruct( after remove the difference on the z value) to calculate only angle around z(vertical) axis angle difference of each plane, ten project that to the plane height 

is that right/or close?

Acrually I need another angle:

I have to import only the guide line on SCIA Engineering, then in SCIA I choose a profile for the lines, so that the lines turn into beams.
When I set a beam profile, I have to specify some parameters such as the position of the member respect to the guide line (top/bottom/left/right..), the eccentricities and above all the rotation respect to beam's z axis. if I just leave 0° I get interpenetration of members.
So I have to import in SCIA the rotation of each beam: I have to export from Rhino an excel column of rotations' data and import that column of data in the LCS Rotation [deg] column of SCIA.

I show you the angle I need:
For horyzontal membersFor vertical mambersThis is what I get when I set the profile on the wireframe scheleter on SCIA, note the column on the Table Imput " LCS Rotation [deg[ " with 0.00°

I guess from your new illustrations that you need to compare plane of the frame to the frame of the fixing point 

but not the vector of the frame, because tilting mean more tan one frame one define frame standing, and other define fixing point frame

define 3 points for each member to define its own plane(ex: purple points + one vertical normal end point), each frame mean 3 different rotation axis angles compared to the fixing point 3 rotation axis angles
