I've tested in versions 2.92, 2.93 and 3.0.
I open a new project, add an empty grease pencil object, paint a stroke, select it and go into edit mode. But it doesn't show the curve editing that was introduced in 2.92
https://docs.blender.org/manual/en/latest/grease_pencil/modes/edit/curve_editing.html
What am I doing wrong?
The documentation says
Select the desired strokes to edit as curves.
Activate curve editing in the 3D Viewport’s header with the toggle button (Bézier curve icon).
Once activated you can:
Edit the curves with the curve handles.
Select strokes to automatically convert them to curves.
But that icon is just not there.
Thanks in advance
