I'm trying to sketch a 3D helix curve that I can use as a driving sketch.
I'm modelling an assembly of a segmented coolant hose that I intend using as support.
I need to create a nice assembly (and render) of the part to show the customer etc.
I'm certain there must be a way of creating said sketch but normally I have little need to produce 3D sketches so my knowledge in this area is somewhat lacking.

Thanks in advance

Michael
