pretty straight forward.
you change the orientation by changing how you place the items on the printbed.

a long pice can either be printed lying down or on end. That will change how the layers are placed.

The other way is to have 100% infill and no shells or top and bottom layers.
You should be able to adjust the angle and type of infill to change how things are printed. If you can't do it in cura (and I really don't like cura) you can in simplify 3d.

Also check out the prusa slicer, that should also let you adjust infill angle.
