Has anyone modeled a ribbon cable folded over at 90 degrees so that the end
result is a 90degree bend in the plane of the cable.
This looks easy, but I have spent way too much time on this already.

CADitis ... wasting disease, symtoms are excessive ellaboration of CAD
models beyond that which is strictly necessary, but which feels real good at
Especially easy to catch from 3D cad.
Just BTW, in case you're contemplating using ribbon cables in a design
where cost is important (and when is cost NOT important?):
There are a couple of different types of ribbon cable. One is called
flat printed circuit (FPC) cable, which is just what it sounds like --
cable actually etched from copper-clad laminate stock, and then usually
laminated with more (un-clad) stock and plated to prevent oxidation of
exposed copper. Natually it can connect however you need it to, and
even be integral with non-flexible printed circuit board. It ain't
cheap, though, because of the multiple operations it takes to produce
it, and it can get pretty darn expensive if it's complex . . .
expecially when designed as rigid-flex printed circuit.
Another type is called flat flex cable (FPC), and it's basically just
flattened wire laminated on both sides and exposed on one side at the
ends. It typically fits into ZIF (zero insertion force) or LIF (low
insertion force) connectors which are soldered onto non-flexible printed
circuit board. Obviously this is just straight point-to-point
connection, which can't always server the same purposes as FPC, but it
is a hell of a lot cheaper when it can be used, even considering the
cost of the ZIF or LIF connectors and soldering.
