As the column enters, the opening line becomes thinner.
How do I get this line to be the original line?

after display order

All I managed to do is draft a polyline with the proper thickness on top of it, to make it look tidy.

As far as I know you're not doing anything wrong and Archicad is being weird.

thank you so much.

I also think it's a bug.

If you don't want to draw a line, you should set it to 0.
And you will have to raise the wall up.
