Err luk. Where is all the craftsmen gorn.
We're still here, just not valued anymore.
Cone is better for segmental bends, despite its name, tubemitre is for branches, (coping), thread covering it here.

If you set the offset to greater than the tube diameter with an angle then it will work out angles like what you need in segmented bends.We're still here, just not valued anymore.

I need to put a 20 deg bend in 38 mm thin wall tube,
five large radius 20 deg bends
I'd never heard of this so I spent a few hours googling it and it seems a 90 degree bend is usually recommended to be 6 pieces which would be 15 degrees each so your bend should be fine with just one cut but 2 pieces of 10 degrees would be better if you wanted it to looked more curved.
Could someone tell how to draw these out by hand without any computers. Looking at the shape of the curve when its unrolled (like a template) It looks like there should be an equation plot the shape on a graph, something along the lines of y = x*sin(56...
It would appear You can draw any cross section you want where your 45* is, here's my coped tube following your method:Here's a brief explaination, found this somewhere on the web a while ago when trying to explain it to someone in work

This is for diameter 90 @ 45 degrees but its the same principle for any diameter/angle

That's What I meant.I'm not quite sure what you mean by around the curve at the bottom,
Are you looking for the best way of equally bisecting the radius that's drawn at the bottom left of the sheet?
If the two intersecting tubes are the same diameter then it will always be the centreline of the tube. If they are of different diameters then the smaller one will only reach its' own diameter.Is there a way of accurately marking how far around the curve at the bottom you measure up?
