to create intersection lines

I often need to create an axis on the intersection of two planes.To do so, is it necessary to create a sketch and a line in the sketch, or is it possible to just select the planes and say "create construction line" and you get a kind of "3D rectilinear curve"?
And same question for an intersection curve. Is it possible to create a plane curve that is for example the intersection of a plane and a face?
And finally, is it possible to create a 3D curve at the intersection of two faces?

I hope this helps

Why do you need to create an 'axis'? In Onshape, exes are defined by circular edges, cylindrical faces and conical faces.
It is possible to create a custom feature that would create a (finite) construction line at the intersection of two curves (you would need some way to define the length of the line and its starting point).
Yes you can generate the 3D curve at the intersection of two faces - i will make an example a little later.
Sorry for the lack of politeness in my first message
My question is not critical at all!
What I call "axis" is any construction line that I need to place in 3D space. Such a line is often for me a way to build a new plane with a given orientation respect to other references, in order to sketch a new shape.
For example in the picture below , I built "Plane 1" with an angle from Top plane, after having drawn a line on the intersection of Top and Right planes.
To draw this line I had to create a sketch, but it would have been just a bit easier if I could select the planes and ask for the intersection line.
As you can see it is not critical, and may be it is possible in fact (?)
Waiting for the example on how to create the intersection curve of 2 faces.
Best regards.

Thanks a lot!
That is very strange, The document is public and opened for me with no issues. Could you please try again, if it fails to open, post a snapshot with error message here. Thank you.
It's working now. I haven't figured out completely whats going on, but its something with the way I log in with the enterprise license. If I go from our enterprise it doesn't work. If I login to cad.onshape.com first, then it works fine.
I'll try to remember to take a screenshot if it happens again.
