BIMcloud warnings are getting out of control

[Patrick M]

here is a small sampling of the t/w warnings I have been trouble shooting the past week. This feels like something is broken... or theres something else at play here (my tinfoil hat is on pretty tight right now). And these are about 1/4-1/2 of what I've been sent:

No reaching out for me until now. 
Separately I have talked to GS Support because I submitted a bug report and got the "stair solution" ( “Rules & Standards” > “Walking Line Calculation & Symbol” > Remove the checkmark next to “Tapered tread width” • “Rules & Standards” > “Calculate length” > Must be set to “Along arc (legacy).”) This worked for 2 weeks, error is still there. 
Our local partner is useless, any problem we might have they have no idea.

Hi James,
To clarify, there's a dot after "@Kevin Lee" in my original reply. In Ernest's case, we suggested entering a new ticket or reopening the support case whose closing didn't meet his expectations.

Best regards,

Focusing on the thread and sharing our own experience, we have also been struggling with numerous vague errors since transitioning to Archicad 29.

While the resulting downtime and user frustration have been challenging and, at times, disheartening for those in my position, we have been consistently submitting logs and sharing reports through our local support team. 

I have recently been informed that the development team is now prioritising these fixes. As some of these improvements are included in the latest preview update, I highly recommend that everyone conducts their own testing and sends logs to the local support team to escalate the issues. So far, I haven't had the error for the last 5 days... touch wood.

I'm really REALLY hoping this upcoming update (3/24?) fixes these kinds of issues...
user one adds a turned cabinet trim with a shell. user two does a s/r and sees... not the same thing...
teamwork isn't just unreliable, its wrong. its broken! 
but I'm sure it's something in the file making a simple revolved shell show 2 different ways... 
...
IDK, I'm not infallible. Maybe I'm missing a simple answer to this one... is there some MVO or shell setting that manages LOD that could make it show 2 different ways? none that I'm aware of.

@Patrick M If you are currently using AC29, try consider updating to the preview version. On my end, the issues you described were only occurring in AC29, and installing theAC29  preview update seems to have resolved them over the last few days.

I have done the same in the past. There are a few reasons why I no longer do this.

You have no way of getting beyond first-level support. That is why a typical support case will look like this: 

save teamwork into PLN, create a new teamwork project, reimport the PLN.

Can you open up the brand-new teamwork without any errors? Good, problem solved! Thanks for wasting an hour, byebye.

At least that is how support cases work for us at IDC. Again, not blaming IDC. But I was not able to get into contact with second-level support for over a year. Heck, there is no ticketing support system, not even an e-mail address. Or at least the chance of getting a link to an internal ticket, after first level support opened up one for you. How embarrassing is that? How should anyone at GS be able to solve problems, if they can't even directly contact the customer?

So that is why we have given up. You only invest time and there is nothing gets out of it.

If Graphisoft is still stuck in the past, and thinks of me as an "annoying user that only creates support costs" instead of what I am actually doing, which is free QA, I can't change that. 

We changed our update strategy. We now look at the current version number (29) as a release candidate and think of ArchiCAD 28 as a stable release.

Hi all - 

We've been dealing with this for over a month now in a real and painful way. I posted here about it: https://community.graphisoft.com/t5/Teamwork-BIMcloud/Archicad-29-is-unusable-due-to-Teamwork-errors...

That post describes a way that we were able to go from the 5 of us having this error multiple times per day on AC 29 to one of us getting hit once every few days. So not a fix, but it did lessen the symptoms. 

I didn't share in that post, but I will here, we did extensive network troubleshooting as it really does feel like a hardware related error. I can assure you, at least in our case, it is not. We tried a different network switch, different cabling, different server NIC, different client NIC's, All while having no other network errors. We did a full clean re-install of BimServer Basic. Full Clean (completely clean, no user config, nothing) wipe and reinstall of AC29. 

As I said in the other thread, very disappointed in the limited support GS North America gave us as BimServer Basic is a non-supported product. Even with us being SSA members.

Please check out my post in the other thread, it might give you a little relief while we all wait for Graphisoft to do something for us. I owe my improvement to others, if only I remembered who so I could give credit.

@Joe_Paetzel 
I have been testing this out since December, when we first moved to AC29 + BIMcloud (from bimcloud basic).
I am BIM manager at a firm of over 100 people, and I occasionally consult with about 4-5 other firms.
...
I can confirm, this is not a file issue, not a network issue, not a hardware issue, not an OS issue... 
You can see from the first time I posted this thread, 2024, this is not a recent or new issue. But since the move to AC29 and the move to the cloud SaaS, it has gotten out of control. 
I went from 1-2 per month, maybe 2-3 per week on a bad week, to daily.
...
Since I first posted this and started the conversation with Graphisoft, it has always been pointing fingers at something WE were doing wrong. in 2024, they claimed it was our BIM server configuration (actual server, not the app/interface), our network settings, our VPN, etc. etc. etc.
We moved to the cloud service at the end of 2025. That being the instigation of things careening downhill is a clear indication that, if anything, our server and bimcloud basic were keeping the sh**Storm at bay. 
Most recently, I have heard that it is likely our files or our libraries. Never mind that those did not change from November '25 to January '26. Graphisoft continues to pick apart our files, as if there is something in there that is the culprit, instead of something in their software.
I get it; I don't know software engineering. I only have the most sophomoric idea of how the software works, or rather, doesn't work. But if this is an issue with my files, it is technically an issue with Archicad and BIMcloud being incapable, suddenly, of supporting my files. I'll be the first to admit, I could do a better job of auditing and maintaining file health. But the files worked, and now they don't.

I am currently sucipicious that this is a BIMcloud issue. We have people reporting that they make 2-3 changes, and the first change goes through, but the subsequent changes don't. Even though they are all made within the scope of a single s/r. The bim server manager reports that the send went through, but that has become meaningless, as people are losing more and more work every day.

It seems, to my idiot brain, that BIMcloud is somehow putting some of the local data into a trash bin, instead of sync'ing with the server data. Sometimes is 2d stuff on a worksheet that wont go through while model geometry will. Sometimes its railings or curtain walls that the server rejects, but walls and slabs will. Additionally, we see that if we have 7-8 people in a project, 1-2 people may not be able to send anything, while the rest have no issues. More times than not, it's people working on 2d drawings (details/worksheets) that have this problem.
At this point, my main job (100 person firm) has even started the conversation of how much work do we lose before we start the transition to Revit. Losing $20-40,000/month is a LOT. Tooling up to Revit is a lot more... but at some point, morale and workplace motivation plays a bigger factor than the dollars.
And while I know Revit sucks too... thats hardly a winning argument with the frustration designers and coordinators are dealing with, and the continued "it's probably your (insert archicad feature here), not the software" response from GS.
Personally, I'm well past my breaking point on this one.

18 months since this thread originated. I just took stock of the number of responders... It appears in this thread alone, at least 13 people have shared similar experiences over the last year and a half.
I have had 63 individuals, among 3 firms, report to me in the last 3 months alone. 
The firm with the most reports also shared:
2024 office wide monthly overhead average: 44 Hours
2025 office Wide monthly overhead average: 52 hours
Jan 2026 monthly overhead: 151 Hours
Feb 2026 monthly overhead: 120 Hours
The increase in overhead time in their office management system indicates "IT/Overhead" with many notes to the effect "rework" or "lost work". This is not a "we hired a new HR/Overhead dedicated personnel" increase.
...
We are losing money using Archicad.
...
When Archicad 18 was released, there was a bug that would cause the entire view map to be wiped clean. That bug was catastrophic, but the cause was found within weeks, and a repair was available immediately.
There was no suggestion that "you should just avoid using _my views_ and _my layouts_". It was just fixed.
Now we have more of a slow bleed, over the course of 18 months. And all we get are suggestions tantamount to "maybe you should look at a bandaid, and try not to cut yourself in the future".
...
The archicad 18 bug was BAD. But it did not result in any of my clients even mentioning Revit. After 18 months of deflecting to "it's probably something you are doing wrong", I am getting multiple people asking me what it would take to switch platforms.
...
in my review of this thread, realizing how LONG this has been dragging out with no indication that we will have a stable and reliable Archicad and BIMcloud, I'm at a loss. Disheartened and defeated doesn't begin to describe how I'm feeling. Every day I sit at my desk, I'm dreading the first slack or discord message with an attachment... I know i'm going to have to tell someone that they need to redo their work from the last few hours or even days. I know at some point in the next week, I'm going to need to talk a project team down from trying to pull consecutive all-nighters to get back on track for a pending deadline.
...
Every time I get a glimmer of hope... I was notified "we found something in the layers that may be preventing teamwork operations"; but that was followed up by "we need to find what is wrong with your files".
Graphisoft needs to come to a complete consensus, that NO MATTER WHAT MAY BE WRONG WITH ANY FILE, it should NEVER result in the loss of 100+ hours of work per month for any firm.
If BIMcloud or Archicad can not perform basic data stability and security, I see no reason I should argue with a firm asking for an evaluation of cost to maintain a flawed BIM authoring platform vs switching to another (possibly flawed) platform. Yes, a switch to Revit is expensive and fraught with it's own struggles, bugs, and issues. Revit does not have the kind of network, support, and direct contact with development that Graphisoft has typically provided. 
But if the response to bugs, issues, and struggles are that it will always be pushed into something I, and my clients, are doing wrong, then I'd argue Graphisoft no longer has the support it once did. Can we get Graphisoft back to the company that took bugs seriously, back in 2014?

[Patrick M]

maybe BIMcloud is taking responsibility for it's own inadequacies...?...
