LOS: Windows Question

[celestian]

Do "windows" work like walls or do they work like doors (need to be enclosed)
meaning can I just draw a straight line and that function like a "window" or does it need to be a rectangle.

Because this:

Looks like this:

That seems to imply it needs to be enclosed but perhaps I am wrong.

I would very much like it to function like a WALL (same for illusion/pit) and NOT like doors personally.

You can use the single line drawing. It does keep you from passing through the edge. It does let players see/use the "open/close" for the entire space.
