is this file too big

[yanyan77]

we are working on the DD phase of a high school, which is above 400,000 sqft.
now the file size is beyond 160MB, which makes my computer crash a lot.
we put all the furniture and equipment in a linked file.

[mthurnauer]

160MB should not be too big, but it all depends on your computing power.

Time to start thinking about moving to a 64-bit OS if you're still 32-bit. The upgrade will go a long way towards stability.

[cliff collins]

Per Autodesk,
the Rule of thumb is compressed Revit file size x 20 = amount of RAM required

160 MB x 20 = 3.2 GB RAM

32 bit OS can only use 4 GB RAM with 3GB switch enabled.
1 GB is needed to run Windows, other apps, etc.

The 160 MB Revit file will require more RAM than is available on the 32 bit machine.
This will cause crashes, and even the inability to Synch to Central or Open the file.
Then throw in a linked Structural and MEP model, and you are in trouble.

So-- as mentioned--it's time to upgrade to 64 bit OS and 64 bit Revit.
Now you can add much more RAM, and thus run larger projects.

32 bit systems are dead. I don't think you can even buy a new computer with 32 bit OS?

LOL

we have not link any mechanic and structure file yet.
and i do not think my office want to update my computer now.

[cliff collins]

Reality won't budge.

Try purging and reducing file size.

LOL

[yanyan77]

I hate work on it now.
i shut down the computer and restart many times in a day.
even i want to purge , it does not allow me to do it.
because it is out of memory.

my co-worker has a 64 bit computer, but we do not know how to reduce the file size.

[cliff collins]

Aha!

Mixing and matching 32 bit and 64 bit OS is possible, but not recommended,
because on large projects, like yours, when more than 4 GB of RAM is required,
the 64 bit machine ( if equipped with more than 4 GB RAM ) will be able to Synch
to Central, and save the large file.

However, the 32 bit machine, with its RAM limitation of 2-3 GB of RAM available,
will not be able to Open, Synchronize, or Purge--as you are discovering.

Explain this in real-world economic terms to the Management, and they will soon understand that if you want to work on large projects in Revit, you MUST upgrade the computers.

Is a project using Worksets? If so, only open the portion (workset) you need to work on. This will put only the demand on the machine from that workset.

yes. we have more than 20 worksets.
each unit in each floor is one workset.
if we combine some workset together, can the file become smaller?

[Scott D Davis]

No don't combine worksets. Just open only what you need to work on. In the open dialog box, there is a drop-down menu to specify a workset to open. If you need to work on "unit A', then open the Unit A workset ONLY and work on it, then save to central. You don't need to open the entire model with all worksets.
