Incorrectly oriented (rotated) section views

[NewJoker]

Hi,

I've noticed that section views are incorrectly oriented (rotated) with respect to their corresponding views in 0.21 dev version.

Here's what it looks like in 0.20.1 stable:

section example 2.JPG (17.6 KiB) Viewed 1675 times

And here's what it looks like in 0.21 dev:

section example 1.JPG (18.88 KiB) Viewed 1675 times

I guess that this behavior is caused by changes introduced with the new Complex Section tool. I know that section views can be rotated but would it be possible to make their default orientation consistent with FreeCAD 0.20 ?

@FBXL5 is teaching me about correct orientation of section views - https://www.forum.freecadweb.org/viewto ... 52#p646152 - so there might be some changes in this area soon.

Please post a file that exhibits the problem, as it doesn't show up in this trivial test:

I must be doing something wrong. I don't get any difference using your file with v.20 and v.21. My v0.20 is a snap version - I wonder if that is significant.

Maybe it's because you are using Linux or a newer build. My colleague has the same issue with his model. He's also using the newest build available for Windows.

I tested the complex cuts: I must not have understood everything yet because my results are not always those expected!
I'll come back to the forum if I can't.

@user1234 Thanks for the info, but I'm only using the released updates, and the latest one, released yesterday, doesn't have the fix yet.
The same file produces the same error, but I noticed that the error does not occur if the section plane is horizontal.

@user1234 Then I will tests it once this PR is merged and included in Windows build. But it’s for the new Complex Section tool so I’m not sure if it can also fix the behavior occuring with standard section.

[wandererfan]

Well, I don't know what is going on. I tested 3 different versions on Windows and they all produced the same section view - the one with the section view "lying flat".

The PR version produces a new or edited view with the section view "lying upright", but the untouched view is still "lying flat".
I'll try downloading the current stable v0.20 and current Appimage v0.21 later today.
