I tried to save a fairly large assembly as STL and got this message:

Due to the lack of available virtual memory your STL request has been terminated.

Please increase ypur STL deviation and/or angular tolerance or increase the available memory for your system.

At no time in the run-up to this error did the memory used increase beyond about 8.5GB, in a machine with 16GB fitted.

I imagine this error message may not mean what it says, but what does it mean?

How can I STL this file?
