line thickens floor / section

[Anonymous]

Hello,
I have a trouble with line thickness in section. The line thickness in section is diffferent from line in floor. In floorplan is it correct. (see attachament). I belive there is a simple solution of this, but I am begginer in archicad.

Does anyone know how to fix this issue?
Thanks in advance for any help on this.

I use archicad 21, OS Win 10.

You might be using different pen sets on your plan and section view.
Plan looks like in B&W while section is in coloured. Having different pensets can also control the pen weights especially if you don't want to edit individual elements pen settings.

Another might be the views are at different scale.
Hope it helps.
