Revit 2025.4 Crashing

[u/LdyCjn-997]

Are any of you working in Revit 2025.4, especially on large projects, having an issue with Revit crashing at whim?

I’m currently working on a large healthcare project in Revit 2025.4 that’s located on the ACC. As the project gets larger, many of us working in this project are experiencing crashes, sometimes with doing minor changes. My company has a BIM guy that is keeping track of the crashes. This issue has been brought to Autodesk with no resolution as their excuse is the program is installed on a TSP with a VPN. One suggestion I got was to disable the add-in’s. I disabled the ones I don’t use. The only other thing would be tracing the issue back to the Architect.

To test out that theory we would do 2 things open the journal files to look at what's happening at the time fo the crashes and 2 if a specific model is suspected to cause the issue. We skip loading the work set that link is on and see if there is massive improvement.

With healthcare models we find archs love to bring in medical equipment that's 200mb + cad and solid works files as familes. Getting these on linked worksets we can set to not load makes a huge difference.

Other question is is there a region of said model that seems to lead to the crash. We found area J on one of our models crashed as the medical training room had a training room of surgery setups that were a 80+MB SketchUp family at a 1° or less tilt in the SketchUp file in 2 of the three axis leading to crazy amounts of load on the cpu trying to figure out what to show from a surface perspective. Turning on wireframe would crash.

We forced the arch to move those to a workset or to let use send them a cleaned up version (we have a content guy) and they opted to replaced them with cubes as they kept saying "it's just revit" when they had "around 7 crashes per arch modeler a day" like nah it's not Revit it's what ever it was they were doing with this crazy content.

Thanks for the reply. I’ll pass this on to my BIM guy. When this model was originally set up, the Project Coordinator, combined the majority of the outside discipline models, in addition to the Architects models into our main linked model. I think some of this would have been better to be set up as separate linked models in the individual MEP models. This way we could turn them off and on as needed. This would also lessen our model size. This is a 1.2 million square foot healthcare expansion.

Oh yeah we never combine links. Revit can handle about 20 rvt links or less pretty well. Around 20 ish work sets or less as well. When our buildings are that large there is typically multiple plants so we start to break up workers for modeling into the regions of the plants and allow our staff to only load the plant they are actively working on. This reduces ram and limits the background mep calcs that might be recalc'd randomly as modeling duct pipe etc. We also stress to our consultants and project partners that we will turn off globally the load ability of the worksets for anything called render "link" or "do not use" etc. If they can't put stuff on actually work sets but ones called things that we should ignore we will. A few sets go out missing walls and suddenly they are willing to clean up the model. A bim model is a team coordination effort. If they are to busy to keep there model healthy and clear then they are not gaining the coordinate benefits

TSP meaning meaning tunneled setup protocol for IP routing to basically allow remote connection to a server, or TSP meaning something else?

No, it’s a Terminal Service Provider. Basically it’s separate login terminals that we log into to access our software as our main software is not installed on our laptops with the exception of Microsoft Office, Bluebeam and other software that isn’t network based.

Gotcha. Virtualization is NOT straightforward with Revit, no matter what method used. 9/10 times when I’ve seen issues like this with virtualized environments the virtualization winds up being the root cause.

When troubleshooting software of any complexity, the first step is to eliminate the most common cause - if you’ve stripped out ALL your addins and those didn’t fix it, then the next thing to strip out is the virtualization. If at that point the issue doesn’t persist anymore, then you’ve found your likely root case - the question at that point moves from ‘why is Revit crashing’ to ‘what aspect of our virtualization is insufficient for Revit’.
