Hi
I am trying to define the orientation of the beam of a 3D frame with Linear Transformation but I don't Know how you get the local axis of the element 2 in the user's manual. I think the y and z local axis in element 2 must be the oposite after do the cross product of the axis x and 0 1 0.
And I have tested and the linear loads works but the direction is the oposite of the local axis.
Here I send you my test file
May you tell me if I am right or not and how it's works ?
Thanks.
