I have a large assembly that I would like to open inlightweight mode. I've experimented with different combinations of'large assembly mode' toggle (tools/options/assemblies) &'always load components lightweight' toggle (under performance).

I receive this error:

'SW encountered an error opening the document. Please contact yourlocal rep for help troubleshooting this problem'

I actually need to close SW to pull in up (re-toggling alone won'twork). Any ideas as to what might be happening?

Thanks!SolidworksAssemblies
