Change line pen at edge of window (window contour line?)

[Anonymous]

Does anyone know how to edit the red line at the upper side of the window in the attached picture? From other reading I believe it may be the window contour line. It is pen 3, which I would like to change, but cannot find where to do so.

It is not in window settings, wall settings, any relevant material settings and it does not matter if the wall is basic or composite, nothing changes. I can't for the life of me find it. A similar line appears on doors, which I would like to change as well.

Any help would be great!

If the wall is not 'Symbolic' then it is the wall line that controls it.

I also feel a bit sheepish.

But I noticed that when the 'Wall Contour Lines' is turned there are no settings. and there is no arrow. Logical. When you turn them on the settings don't expand, only the arrow appears.
Keeps you sharp.

Hi there,
This line pen is only editable with specific windows, but for the Terrace Door for example, it doesn't appear. You can't change the wall countour line on plan, there is only option for changing the linetype, but not the linepen.
