How to rotate an element a different angle than 90 degres?

[Jatfuentes]

Hi ,

I am modeling a building, where the axis of the building are not orthogonal.
I want to aling the web of my column with inclined axis of the building. I tried to use in member modification option --> orientation options ~~~> rotate, and inputed 23 degrees but the rotation always is 90 degres.Why ?.
I doing something wrong?.
There is another method to rotate a column any angle ?

Thanks if you can help me

In RISA-3D, you should be able to rotate any angle.... If you are using RISA-2D, however, then you can only rotate in 90 degree increments.
