You don't say what version of Archicad you are using.
Please add details to you signature in the PROFILE link at the top of the forum.
If you are using 16 or 17 then you can convert it to a Morph and freely rotate it any way you want.
You will also find it easy to edit as a Morph.
Do you know there is a Truss Maker in the Design > Design Extras menu?
I'm not saying it is good or will do what you want but it is there.
Look up in HELP how to use it.
Also you may find a few truss objects ready made in the library - maybe one of those is suitable?
