Walls appear on plan but do not show in 3D?

Glenn Berger — Wed, 24 May 2023 07:09:58 GMT

I've drawn a group of complex walls. When viewing in 3D some walls not visible. I dragged a copy of all the walls to 50ft away and all walls showed. Then replaced the missing walls ( still there in plan view) with the duplicates. Problem solved. What is going on? I've reused the same file saved as for similar projects since archicad 10. Is this relevant?

Thanks the forum is always helpful.

Check that you don't have two or more exact duplicate walls in exactly the same space.
These will show in plan but as the walls trim each other in 3D they may seem to disappear.
Use the "check for duplicates" add-on (goodie download from HELP menu) to check for all duplicates in you plan.

Thanks Berry,

I have the same issue. I was hoping your fix would work, but I double checked the walls and none have a duplicate. This issue seems to occur with complex walls. I have never seen it occur otherwise. I don't want to assume it's a glitch in the software, but it seems to be. I'm hoping there is something I'm missing. I can pull the wall away from the corner and it appears (of course without a clean corner). When it is properly connected at the corner, the wall disappears. Thanks in advance to anyone who has a solution!

Please ignore my first image- I did not intend to post it. Here are paired plan & 3D model views. The first is a clean corner where the wall disappears in 3D. The second pulls the wall and it shows up in 3D. Thanks again!

Is that window in the wall that is disappearing?

That's OK, I have been called worse.

It seems to be an issue with the complex profile wall and the corner connection.
I have not seen it with a 90° connection, but I have had problems when the walls are at a very slight angle to each other - similar to the image you did not mean to post (right hand side).

It is very hard to guess what the problem is without seeing the file.
Maybe select the walls in plan, save selection as a MOD file, zip the file and attach it here.
There should be no need to share the whole file (at this stage at least).

I don't know if this is related (slightly different situation with complex profiles), but it seems there can be problems when the complex profiles get a little too complex.
The connection become so complex that some of the geometry starts disappearing.

This can also occur when you have two walls overlapping, check to see if you have walls in an identical position even on a layer that is turned off

Hi Luke,

Thank you for the report and I am sorry about the issue!

I have come across this issue once, where the window was the one making the wall disappear. But in that case, the wall stood alone, no connection was made to any neighboring wall. Could you try to delete the window and see if it brings back the wall when the wall is connected properly?

Thank you very much!

Best regards,
MInh

A slab with a building material with higher priority than that of the wall on a hidden layer will cause the wall to disappear and the window to remain. Provided the layers have the same intersection group number.

Turn on all layers and take a look in 3D if there is a slab somewhere.

Thank you everyone for your responses! Mlnh, when I deleted the window, the wall showed back up. I tried the same thing with another disappearing wall, this time with a door (same complex wall profile), and it worked as well- the wall showed up when I deleted the door. I have about a half dozen disappearing walls in this project. Many of the walls with the same profile and window work fine for some reason. They all have Cad Image doors/ windows. How can we fix the issue? Do you need a file as Barry suggested? Barry, thanks for the forgiveness btw

Complex profiles and openings, try changing the reference point for the relevant doors and windows?

Hi all,

With the help from Luke, I was able to identify what is causing the issue. As Barry suggests, the issue lies in the complex elements in the profile, in this case 3 small circles, 2 of them were created from many small segments.

By removing these three circles, the issue is eliminated.

I hope this might come in handy if you come across this issue in the future.

Have a great weekend!

Best regards,
Minh
