Opening doesn't show in some wall types

[CFS_Mike]

I have a funny issue with placing an opening in a wall. In plan view, the opening will only show in certain wall structures. If I use a standard "background fill" for an existing wall and place a new opening in it, it will not show up in plan (but it shows in 3D). But if, I change the wall to a standard "50%", then the opening shows up. I have checked my cut planes and it is set correctly. I have developed the work around to only use certain structures of walls, but I'd really like to know why an opening won't appear in certain walls. Thanks!

So, you've already started a process of elimination. Check the following in order:

1. Model view in particular view. Check through the door and window settings.
2. Renovation filter and elements renovation settings.
3. Graphic override (this shouldn't be it, but check in anyway).
4. Pick up the properties of the door, delete it and place it again. Does it have the same issue?

It's not the opening itself, it's the wall type. I have checked through your list and we found nothing that helps the issue. I can get the opening to show up if I have the wall a certain type of structure in use, but some will not show an opening. These are the standard Archicad building materials and composites.

Sorry for the late reply, Mike. 

Did you try deleting the wall and replacing it?

Sometimes, when I get a glitch that is inexplicable, I delete the element and replace it (ensuring renovation and dimensions are in mind). Then I save the file, close it, and open it.
