Wall in 3d invisible

[Anonymous]

Hi. I have just started to use archicad 17, but my walls are invisible in the 3d window, anybody any ideas how to fix it. Many Thanks

Renovation Filter

Hi paulandrew,

Did changing the renovation filter fix the problem for you?

We are having a similar problem where the wall appears in plan, but in elevation and 3D views the wall is missing but the windows and doors show. Please see the attached screenshot. Deleting the window makes the wall reappear, but reinserting the window makes the wall disappear again.

This is a recurring problem on this project; just about every 3 weeks we find this situation on some random wall in one of the seven buildings.

I suspect it may be related to the window's settings, but there are countless other windows on the same building with the same settings where the wall is unaffected.

Any ideas?

If you are sure it is not a renovation filter (i.e. make sure the current filter is SHOWING everything) then turn all your layers on and check in plan to see if you have 2 or more walls in the one location.
Overlapping or duplicate walls can cancel each other out in 3D.

Barry.

In older versions of ArchiCAD we would strike an issue like this every now and then when a window was right at the end of a wall. It wouldn't always do it, only sometimes.

The solution was to move the offending window 0.1mm away from the end of the wall, that way the wall would re-appear and the dimensions would still read correctly.

If none of the previously mentioned solutions work maybe you are experiencing this bug?

I have been caught with invisible walls, in 3D, turned out they had no height, usually the cure for these things is something simple.

Thanks for the suggestions everyone! Yesterday a coworker fixed the wall by deleting it and re-creating it, so I'll give these things a try if this happens again and report back (although it may be a while before this problem happens again, lol.)

Before my coworker re-created the wall I did double check the renovation filter, but it doesn't appear to be the issue here.

There are two coplanar walls in that location. The extra walls are in a hotlink module, on a layer that is turned off and with a different intersection priority number. But that same double-wall condition happens with every exterior wall in all 7 buildings, and the problem seems to affect one random wall in one random building every once in a while. And I am nearly positive that when the problem first occurred months ago it was before the second set of walls was added. Next time this problem happens I will try removing the extra set of walls from the hotlink module and report back.

I had the idea to keep a copy of each offending wall in a separate solo project file so I could compare and study them to see if I could figure out what the problem is. I asked my coworker to do this before he re-created the wall. When I opened the solo project to examine the wall, the entire wall showed correctly in 3D! So the problem does appear to be caused by some local condition (maybe the extra walls?)

So the invisible wall problem struck again today. As it turned out there are two walls that were on top of each other adjacent to the invisible wall. Resolving the duplicate walls issue caused the invisible wall to reappear.

Thanks for your help everyone!
