90deg bend after a helix spiral

[James]

Okay - I'm trying to draw a coiled tube around a main cylindar. I've got
the coil part done which was easy but I'm trying to figure out what the
easiest way of creating 90 deg bends off that coil are. Imagine you've
got a coiled bit of copper and you've straightend out the ends to put
fittings on them.

Any suggestions?

I'm thinking you could do it with a sweep along a projected curve. Create a
cylindrical surface to match the hliex you swept along. Now create a sketch
of the bend on a plane parallel to the end of your helix. Project that
sketch onto the cylindrical surface, and you should a have a path to sweep
your bend along.

I've never tried this myself.

Set up a sweep? In fact you might be able to connect the ends with the
helix usnig a composite curve and do the whole thing at once.

I would create the helix, then create the 90 degree bend in a new sketch as
a single line. Then create a 3d sketch convert entities and add a fillet
were necessary, and sweep along the 3d sketch.

I have a torsion spring model that I pulled off the SW website some time ago
that may be what you are asking for. It is the variety that has the ends of
the spring that come off tangentially to the coils, as in wind, wind, wind
and then continue in a straight line.

Or, are you desiring the type that gets to the end and then comes out
parallel to the central axis, so therefore it has to make a 90° bend at the
end of the last coil?

Either way, start with an existing spring model.

I would use a revolve feature. Sketch on the end face, convert the
edges, and use the centerline to control the bend radius and direction.
