[BUG][0.20] "Open sketch in Section View mode" preference has no effect

[Lupin]

It seems that the Sketcher preference "Open sketch in Section View mode" has no effect. I always have to select "view section" (or hotkey Q, S) after opening a sketch even when the option is set.

Will have a look.

Can't reproduce.
Could you :
* update FreeCAD ?
* screenshot your Sketcher/Display preferences ?
* look at Property pane 'View/Section View' when you just open the sketch (need to select the sketch in the tree) ?

Can another one confirm bug ?

This is VisibilityAutomation option as per each sketch. Did you press "Apply to existing sketches" button?

Works as expected here:

I tried this version (with the same result):

I am depending on "weekly-builds" or uwestoehr's installer builds though, so I can't test every version.

Here's a screenshot of the settings:

The property "View/Section View" is set to whatever value is set in the preferences on new sketches and correctly applied to existing ones when pushing the "apply to sketches" button. But even when set to true, section view is not applied when opening a sketch. The property does not change when I select "View Section" from the "Sketch" menu. It's as if the the property and what Sketcher looks for are two different things.

There aren't any messages appearing in the console while doing all of this.

Hi Lupin, greetings to the Community!
My version works perfectly.
Isn't it that your sketch does not intersect any object or does the sketch lie on a lower plane?
Consider that only the objects that are behind the sketch plane will be displayed, so if the sketch intersects an object you will see the sectioning of the part behind it, if the sketch is above the object but does not intersect it you will see the whole object , if the sketch is below the object without intersecting it, the object will not be seen.

The sectioning itself isn't broken, it's just that it isn't applied when opening a sketch.

Look at this simple model:

Opening the sketch it looks like this (even though the "Section View" property of the sketch is set):

After pressing Q,S it looks like this (as it should by itself after opening the sketch):

Hi
.... on my build I confirm no problem

I have the same behaviour here: In the sketch the property "SectionView" is True. Yet Sketcher doesn't start in Section view.

It means that you can have an existing sketch, not in edit mode, where View/Section View is 'true', and when you edit this sketch the section view isn't applied ?
