Hi Pilou, here's an example with a tube that is more tightly bent and cut at a greater angle to show you how there isn't one single tangent direction in a case like this:
When you untrim it then you'll get a natural tube end which does have a single tangent direction.

Hi Tom,
re:

> but this does not work, doesnt it ?
Empty space does not have to stay empty, you can draw in a temporary boundary object, extend to that and then delete the boundary object.

Hi Tom, also re: Extend command - the boundary object does not have to be a curve it can also be something a sphere or a plane.

When you say "Untrim" in this case of this tube what is untrimed ? Curve? Section ? Surface ? ...
Untrim is "Separate" ?
From: Michael Gibson
Hi Pilou, it's this surface here that would be untrimmed, the same one that wants to get extended:
To untrim it, use Edit > Separate on it first to make it an independent single surface not joined to anything else. Then select all its edges and do a Delete. The trimming boundary will be removed and the full underlying surface will be recovered.
The other end that will not be extended needs to be retrimmed.

OK!
And this
Extrude --> Boundary Sphere ?
From: Michael Gibson
Hi Pilou,
re:
> Boundary Extrude --> Sphere ?
I'm sorry I don't understand this question. The mention of a sphere above was about the Edit > Extend command, not the Extrude command.

Sorry I have read Extrude so now i better understand! :)
