Revit 2021 Slowness

[ajuelich]

Hello,

We are in a managed environment and have Revit installed on about 200 machines.  In the past few months we've gotten reports from students of Revit becoming extremely slow and eventually crashing.  Sometimes restarting the machine resolves the issue but it doesn't seem to be a specific time, project, or machine........completely intermittent.  Any ideas on how to move forward on determining the issue and resolving this?  I did patch Revit on all machines as a test and it seems to be more rare now but still occurs.  I did open a case with Autodesk but they haven't offered anything in the past month or so.

Thanks!

Could you please elaborate a little more about the managed environment? Perhaps a little bit more on computer specs so we may rule it out. I felt a like more of your environment would help the community to understand the issues better.

Thanks for your response.  All devices are AD Joined and have a Gigabit connection to on-prem resources and a Gig Internet Pipe.  Machine specs are as follows:

• Intel Core i7-6700
• 16GB Memory
• 256GB SSD
• Intel Gigabit NIC
• AMD FirePro W5100 (4GB Video Memory)

All of these machines are spec'd the same but the issue is random and intermittent.  This would happen on new projects that are not saved on the Network.  A reboot will usually resolve it for a period of time.  All are patched to 2021.1.2.

I could try playing with different driver upgrades but I feel if that was the issue, the problems would be more consistent and predictable.

Thanks!

Couple of questions I wanted to ensure.

1. Do these machine have sufficient page file spaces? Since you mentioned 256GB - I am assuming its the hard disk space - and that there might be all sorts of CAD packages installed, I needed to ask if they are running out of space quickly. I have had that issue in the past.
2. Where do you have "Local File Path..." assigned to? The default is users "Documents" folder. If you have One Drive mapped to it and depending on how much these spaces are allocated to each students it could very well the space issues for local files. I highly recommend to keep an eye on the local files as they grow in size and eventually run out of space as well. Purging now and then is a good practice. 
3. The other specs looks like shouldn't cause any other issues.

See if the points I made above are non issues. It is always difficult to find issues in forums for these kind of topics.

Thanks for your response.

They should have enough space.  They haven't come up on our list of machines with low space although I do know that 256GB is no longer great for these machines.  If I felt it was strictly a space issue, I don't think the issue would go away by doing a reboot or be intermittent on differing machines over time.

The local path stuff should all be the defaults as we don't customize any of that and we currently are not using OneDrive but we do have Folder Redirection enabled on Documents, Music, Pictures, etc.

Support has been extremely slow and unhelpful at this point.  They've asked me to give me the Revit Logs but I have no logs in the location they give me.

Since you mentioned about Folder Redirection enabled on Documents, I am curious what that looks like. Revit's default folder path for Local Path is the Documents folder for each user. The project file is copied into this location for processing before syncing back to the central model. Of course this is before BIM360. BIM360 does the caching and processing in %appdata% folders I think. 

The logs files are the journal files. In my installs they are in the "C:\Users\%username%\AppData\Local\Autodesk\Revit\Autodesk Revit 2022\Journals" for Revit 2022. It would give a good reference to the activities that Revit is doing in the backend. I am sure that's what is referenced as Revit logs. 

If you feel comfortable, I am willing to look into the settings, ini's etc. over something like Google Meet or MS Teams. Please let me know.

[ajuelich]

Thanks!  We wouldn't be redirecting %AppData% but we definitely are for 'Documents' which I know Autodesk doesn't officially support.  Setting up a Google Meet would be great.  Can you somehow message me on the side so we can connect via email?

Hi guys,

Has this issue been resolved yet, as I sit with a very simular problem? Would appreciate your feedback.

[OttoDV]

PC specs are good, i7, 32GB RAM, SSD, enough disk space, Geforce graphics (set up for Revit optimal settings)

[ajuelich]

Hello,

No, it has not been resolved.  It is intermittent enough so it all depends on how much Revit certain classes are using.  After a few months I finally got Autodesk Support to admit they had the ticket in the wrong queue.  I do have next steps from them in terms of log gathering, just waiting for it to happen again.

Hello,

Thank you for your quick response.

I will also start gathering log info in the interim. The strange thing is just all the computer resources are underutilized. CPU running at max 25%, RAM at 60%, SSD at almost nothing, WiFi had some activity but it was due to me being logged in remotely, GPU very little (<10%).

I will keep on digging.

Thank you again.
