Lines showing between two floors in 3D.

Orji David

Hi everyone,

I use ArchiCad 20 and once in a while when working on multiple floors, I see a line showing between two floors. Please how can I make it disappear?


  • Is it visible in an elevation view?
    • Check positioning
    • Check building materials
    • Check Renovation Status
  • Is it only visible in 3D window?
    • Check your 3D Style settings if youare always showing contours


Just a couple of things that could be affecting your view

It is also visible on elevation view

Make sure there are no gaps and no overlaps between the top and bottom heights of the walls.

The surface must line up perfectly (which it looks like they do) and the surface material must be the same (which it looks like they are).
