Ac27-29 Layout - incorrect update of views (various MVOs) ?

[gaba]

ArchiCAD 29.0.2 (3200) INT FULL / standard template/lib etc

I don't know what's going on. 😕

These four drawings are linked to four views.

Each view has different MVO settings for windows and doors.

After updating these four drawings (either together or separately), they display inconsistently with the source views.

 

I tested this example in ArchiCAD 27-29 and unfortunately encountered the same error .

However, everything works correctly in ArchiCAD 26.

What is the problem?
Can someone take a look at the attached PLN source file (Ac29 int) / zip.

What is the problem? Is this just me? Are there any environment settings or other issues?

1. @Patrick M, as I wrote before, to be sure that something is wrong, I finally used the standard template; in the case of Ac29, only the original libpacks (without any custom libraries) - a pure Ac29 project!

2. @Laszlo Nagy, ok, I'll report it to my local Archicad reseller

======================================

Edit

It couldn't be simpler!
I've attached the Ac26 project without external libraries (no doors/windows, etc.). It only contains an internal library with two simple objects, slightly modified to be 2D and 3D.
(downloaded from https://gdl.graphisoft.com/tips-and-tricks/custom-made-model-view-options-object/)

This confirms that, starting with Ac27+, there's a problem with correctly using MVO settings for 3D views inserted into the layout.

On January 11, 2026, I sent a description of the problem to my local ArchiCAD distributor. I attached an MP4+PLN file.
I haven't received a response as to whether my report has been forwarded to Graphisoft.

Three months have passed since January and the release of update 29.1.0, but the problem described in this thread hasn't been resolved. It still exists!

Who else should I report this obvious ArchiCAD bug to?!

I've just seen this post and easily recreated this bug in AC28 INT 28.4.0 (7002) on Windows 10.

New file, default INT template, default settings. Just created 3 basic views with different MVOs. All views are set with "Auto Update".

It's weird that Archicad simply keeps the last updated 3D window and uses it whenever you update a 3D view placed on a layout.

It's not just inside Archicad, it's goes through when you export a pdf as well.

Tested this with Archicad 29.1 4006.

I can confirm this behaviour. I haven't realized this till now because I almost never put 3ds as layouts.

The thing is should we worry for other hidden bugs.

There must be someone from Graphisoft to check here isntead of going this whole process through resellers.

Your file is ready for test. nothing better than this to check.

Is GRAPHISOFT aware of the bug I described in this thread, which has been confirmed by other users?

And when can we expect a fix?

[Laszlo Nagy]

If you reported it to your local reseller, then they forwarded it to GS HQ so they are aware of it.

About time of fix: I would recommend again asking your reseller about this. If they reported it to GS HQ, they probably have a Defect ID and they may be able to get some info about it.

@Laszlo Nagy, A week ago (May 11, 2026), I sent a question to my local reseller asking if and when they had sent Graphisoft a bug report about ArchiCAD (I sent this information to the reseller in January 2026 – I attached a description of the problem, a demo clip, and a mini PLN file).
I've been waiting until today for a response from the local reseller.
Unfortunately, I haven't received any.
Therefore, I conclude that we publish bug reports here on the forum, and other users confirm them, but I don't know if Graphisoft will receive our comments about these bugs. And when will they be fixed?

[Laszlo Nagy]

If the reseller sent it, than Graphisoft has received it.

When specific issues will be fixed, I do not have any information about that.
