Outrageously Large SLDPRT filesize.

Hi All,

I've been working for some time on a pressed metal part file that has
gradually grown in size to over 100MB. The file has become cumbersome
to open and unstable at times due to this. I've run it through
ECOSqueeze and UNFRAG.exe and as yet have had little luck at chopping
much off the filesize.

It's a sheetmetal part with several "forming tool" pressings in it
with configurations for different sizes and combinations of the
pressings. There is also some photoworks data (materials/scene/decal)
attached to the part.

I got a little annoyed with it the other day and saved a copy of it to
work on to try and reduce the file size. I gradually deleted out the
features one by one until I arrived back at the base flange only with
no attached photoworks data. By saving this file and running that
through ECOSqueeze / UNFRAG.exe I ended up with a file that was
another 25MB LARGER than the original file. Doing a "save as" on this
blank file yielded an equally weighty filesize.

Are there any further tips and tricks for reducing the filesize of
this back to sensible levels? I'm sure there's no good reason for this
file to be so large. There's very little complex geometry and I
suspect that the filesize has something to do with the legacy data
contained within that can now be stripped out.

Any advice gratefully received.

Hi Daisy,

thanks for that.

I'm running 2.7 SP2.0. I've got the latest service packs and have been
meaning to upgrade but I've not yet bothered. Sounds like this might
be the perfect excuse to go and have an upgrade and see if that fixes
the problem! Certainly something to try for starters

 

Also try a full rebuild.

This can only be done form a macro now a days.. The call is:

swModel.ForceRebuild3 False

 

Update to at least SolidWorks 2007 SP3.0. This will fix the problems
with file size growing. Files with large sizes should also be fixed
when re-saved under the updated SP.
