I'm looking to create a shape involving a tube which has a 30 or 45 degree
bend.
The simplest version is a hull on two cylinders but the joint is nasty.
It seems like I should be able to use a section of a torus to accomplish
this, but I'm getting stumped on how to define it.

Thoughts?

Perhaps code by Mr. Abakof for spiral extrude or parts of it can help, it has
spiral circle extrude included, if I remember this correctly. To get a pipe,
one has to use same module with just smaller radius and then make Difference
of smaler radius cylinder from larger one.
Difference in radiuses determine pipe wall thickness. Using smaller pieces
positioned at distance from one another and rotated, one can get pipe using
Hull, or if it makes solid then make same thing with smaller raduis and
subtract (make Difference) smaller from larger.
Perhaps it would be necesary to cut off ends if they are closed so leave
pipe somewhat longer on both ends.
