System Information
Operating system: macOS-10.15.7-x86_64-i386-64bit 64 Bits

Blender Version
Broken: version: 3.4.0 Alpha, branch: master, commit date: 2022-09-24 17:57, hash: blender/blender@4e7983e073
Worked: (newest version of Blender that worked as expected)

Short description of error
[Please fill out a short description of the error here]

I'm translating this text to Vietnamese and as I read it, I am trying to follow every step with the software 3.4.0 Alpha in hand to test out the statements, this one in particular at the moment:

https://docs.blender.org/manual/en/dev/modeling/meshes/editing/edge/screw.html#fig-mesh-screw-wood

and I found this statement:

This tool works using open or closed profiles, as well as profiles closed with faces. You can use profiles like an open-edge part that is a part of a complete piece, as well as a closed circle or a half-cut sphere, which will also close the profile end.

specifically this part:

or a half-cut sphere

is NOT TRUE at all. When trying it to the software, but cutting an UV sphere in half and in Edit Mode, selecting the half-cut UV sphere and calling the 'Edge -> Screw', you get the following error message:

I believe that you need the half cut sphere and a separate "string of connected vertices"

Indeed, it's possible to Screw a half-sphere if you also provide a guide profile (such as a single loose edge):

The page mentions this, but overall, it's extremely wordy and contains not only misinformation ("the Axis is specified using angular coordinates") but also plain gibberish... Like this here:

Still using the spring example, you can change the remaining vector for the angles that are not related to the extrusion axis of the spring. Bending the spring with the remaining vectors and creating a profile that will also open and/or close because of the change in starting angular vector values.

I have no idea what this means 😅

I rewrote the page, cutting it down to half its original length while keeping the same examples and offering more accurate/useful information.
