RAM

[Mark Vorstenbosch]

Hi Reviteers

This is a stupid one - the file is running out of memory is there a way that Revit can let go of some of the Memory. PC-Running Win 7, 8 Gig ram, but file can purge but then can not save because not enough memory......

Project size would be helpfull... also have any other files open?

As has been several times on these forums, ( please do a search )

Rule of thumb:

Compacted Revit file size x 20 = amount of memory required

200 MB file x 20 = 4 GB ram

You did not mention your file size?

cheers

FILE SIZE = 350MB.
"As has been several times on these forums, ( please do a search )" no time to do this!!!

There are two suggestions I have:

Close all other open programs on the computer: Word, Outlook, …… then in Revit close all open views, minimize Revit to the task bar and then re select it from the task bar to maximize it. Now try to save.

Also is your copy of Windows 7 64 bit?
If it is the x86 (32 bit) version, you can still quickly run out of memory on larger projects. We have seen this on a few laptops here that were not that old but would not take the Windows 7 x64 image and so were re-imaged with the 32 bit version of Windows 7.

Win7 64 bit

At 350 MB, your project will require 7 GB of ram, this leaves only 1 GB to run the OS and other apps, etc.--which is why you are having low-memory issues. I'm assuming you are using Win 7 64 bit.

The best solution is to add more ram.

How far into the project are you? Do you have a lot of linked files?
Revit Structure, MEP, Interior Design, Site? If so--these are also very taxing
on the project and require even more memory--so the problem will continue
to get worse as the project moves forward, until you add more memory on all machines.

You can obviously purge unused families and get rid of any unnecessary imported/linked cad files, etc. and use worksets sparingly, to make the model run more efficiently.
But these techiniques are not enough to overcome a lack of memory on large projects.

Is it a workset enabled project? How many team members? The more staff working on it,
the more the memory problem will grow and "chaos" that needs to be tempered.

(The reason I mentioned doing a search is that it will SAVE you time--as this subject has
been discussed here many times, with some valuable answers to your question.)
