Base vector coordinate system

I am modeling the anisotropic behavior of a plate that have fibers oriented in different directions. For this purpose, I am using the structural mechanics feature. I am orienting my fibers using a based vector system. Does this system work for angles other than 0,-45,45 and 90? I have not been able to rotate my coordinate system at other angles ( I would like to try 10,15, 25 and so on)

Any advise
