walls show a single plane

christian cuppers — Mon, 21 Sep 2026 00:29:28 GMT

Hi everyone,

I'm trying to create a wall in a specific area, but Archicad isn't displaying the wall correctly. The wall appears to be only one pixel wide instead of 300 mm.

When I place windows, Archicad displays them as floating windows, even though the wall should be there.

Does anyone happen to know how to fix this?

Thanks in advance!

Operating system used: Windows 5101

There could be another wall or maybe a slab in that same area that is trimming your wall away.

It could be in a hidden layer.

Turn all layers on to see what is there.

Or drag the wall you are trying to place away from that area to see what happens to it, does it show as expected.

Barry.

Might you by using the Trim to Roof function? It looks like the exterior face of your wall lines up with the edge of your roof (we still cannot view other peoples images at full size so it is hard to tell...). This function will remove EVERYTHING involved that does not fall within the negative/positive extents of the selected roof.

Looking at the screenshot, you can see a Connection Grip for the wall (I think that's its name - it's that little square icon that appears next to the selected wall) so there are some kind of element connection defined the wall is part of: Cropping, Trimming, SEO. Click the grip and you will see the connections. You may have inadvertently created such a connection. I would try to remove the connections one by one to see what one causes the Wall body to almost disappear.

Yeah, from memory walls will sometimes automatically Trim to roofs if you are drawing in 3D.
