Upgrading from Revit 2016

Anonymous
Not applicable

So we have an issue at our company where a lot of our files are now being upgraded to the newer Revit software. This appears to be very taxing on our computers and takes on average 40 minutes or so per file. Many of our projects have 6 to 7 files that need to be upgraded and thus it is taking a lot of time away from work our employees need to do. Since we have so many files that need upgrading we have decided to build a computer mainly for the purpose of upgrading these files. We want to know what it is that is being taxed most by this upgrading process. Is it the GPU, CPU, or the RAM that is being taxed most with this process. Thank you in advance for your assistance.

The computers range between 24-32 GBs. Most are 24GB though.

If we were to double the RAM to say 64GB would you say that the upgrading will go from 40 or so minutes to something closer to 10 minutes? Also if we were to build a computer mainly for this process what other specs might you recommend?

well its not just RAM to consider there are other factors like how "clean the file is that can also affect the long opening times to and other performance issues

Autodesk has provided this pdf on model performance

be sure that your file is not containing revit links that also need upgrading

These are the specs of our current machine which is doing most the work:

 

CPU: i7 3.33 GHz

RAM 24GB

Video Cards: Nividia GeForce GTX 460 and Nividia Quadro 5000

HDD: Samsung 1TB SSD

 

Based on what I see the machine does meet the specifications that are described in your PDF. So would you recommend an upgrade or is there something else we should try doing?

Monitor a system during these long-running processes to get a better idea of where the bottleneck is.

 

Check CPU use (individual cores, NOT average of all) - is it pegged on one processor, or ticking up and down?  Does it stop partway and then resume?  Check RAM use - is it maxed out, or within acceptable bounds?

 

Check network activity - are you trying to pull data from a remote location through a thin pipe?  Think Superman trying to drink a milkshake through a juicebox straw - doesn't matter how hard he pulls on it, there's only so much that can travel through that narrow pipe at once.  You may need some specific tools to monitor this.  Or pull as much local as possible and then monitor.

 

Check anti-virus/anti-malware activity - is your system scanning everything, every time, all the time?  Check settings for exceptions.  Maybe even turn it off entirely, for testing purposes only.

 

Check your system temp folders, both Windows and program.  Clean them up, empty the garbage as well.  Make sure you have a good amount of space left on your system drive.

 

You'll need to download GPU monitor tools to see if that's the limitation, but I doubt it.  Keep that option last.

40 min is just too long.

 

May I know how large is your Revit file? I always upgrade our file which is about 300MB from 2014, 2015 to 2018, 2017 it only takes about 15 mins.

 

Did you try to detach the model from the central model and then upgrade it?

 

I think you should detach the model first and then purge unused several times. It should be fast.

 

Thank you,
