By doing this, i found that we cannot set up case 2 because when we input 0.707, after running, come back to the windload set up, it remain 1
That's because you have to "completely" define the direction cosines. If you only put one value in, it will be normalized to 1.
For example, if you defined a skewed direction as Xcosine=3 AND Ycosine=4, then:
SQRT(3^2 + 4^2) = 5
therefore:
Xcosine = 3/5 = 0.6 and Ycosine = 4/5 = 0.8
If you just specify Xcosine=3, then the normalization ends up being SQRT(3^2)/3 = 1.0
