modeling beam elements

[Ern]

Hello, everyone.
I press that it is the first time I have to use abaqus. I have to model with beam type elements this component but I can't in any way assign the orientation of the section (I have only one reference system for the whole component). How can I proceed? Could I alternatively use elements truss?

thanks to all

Perhaps this can be closed, since there is already That's another

I can't figure out how to do it.
