bezier curves

do they only bend in one plane?
i need to make a bar that bends right then a hook type thing on the end - up and down and sideways!
thanks all

Press F9(editing). There is a button to set a curve 3D.

By default, yes. But if you hit the ā€˜3Dā€™ button you can bend them any way you please:

Best wishes,

thanks for your help
