阶段性的总结一下、希望对后来者有帮助：

另外、后来在网上看到一些遇到相同问题的讨论：

Hello All,
I was asked to look into an issue with apart that an engineer designed. The saved part is
85megs! The part hasabout 100 features. One of my part with about the same number of
features is less then10 megs. Both the engineer and Iare fairly new to SW so I couldn't
figure out what the problem was.All features weremade from simple extrusions, cuts,
patterns, chamfers, rounds. No complicated surfaces and not drafted yet. I did notice that
a lot of the extrusion and cut features were created as thins.
I would hate to have to recreate the part.
Any help would be appreciated.
Thank you,

This is a problem in Solidworks; two people can design the same identical part and the two
part file sizes can vary widely. If one made lots of changes; rebuilt his model numerous
times withmoved features in the tree; added and removed constraints, modified scetches,
etc, etc..., that file will grow and grow and grow.
Here's the question - do you really need the feature tree? If its a simple part, then its 10 -
15 minutes to redo. If its a complex part, then the feature tree is worthless anyway; save it
out as an iges or parasolid and bring it back in as dumb surface/solid. If you need to make
changes to it afterwards, then cut off what isn't needed and add what is. There's nothing
mystical or magical about having a feature history with a part model.

Thanks for shedding some light on the problem. We had a design review and quite a few
changes were made. Now the file is over 140meg. It takes about a minute to save the darn
part now. Is there any way to purge.. or trim the fat off of this thing? It is getting to the
point where it would be better to recreate the part.

First; get rid of all the fluff; studio, lighting, background graphics; all the stuff that has
nothing to do with the part design. Go to your file options, and check the graphics display
resolution to be sure it isn't unreasonably set high, as well as associated setting. When all
else fails, remodel the part.
I have noticed that similar files have exhibited a size reduction when opened and saved in
next higher version of Solidworks. This recently happened when the company I was
contracting for moved from 2007 to 2008.A mold part I was working onsaved in 2008 at
about half the size as in 2007. That filealso had numerous changes to it, and I was about
to save it out as a parasolid and bring it back in as a dumb model to reduce the size of
assembly file before I noticed the part size dropped from about 100 meg to about 55 meg.

I don't recommend "saving out and bring it back in as dumb geometry." At that point
you've just spent a lot of time creating your masterpiece only to destroy thebeauty of the
parametric software.
If you can, do a File, Save As. This usually does the trick. I believe SW saves a lot of history
data within each file. When you do a Save As, that history goes bye-bye and you start fresh.

I had this same problem with a Solid Works Part a few months ago I tried the save as trick
and it did not work I even sent it in to Support and they were not able to figure it out either. For the record I've never had this problem with a Pro-e part.

Yes, absolutely you need the feature tree.
If its a complicated part, the feature tree is worthless if you don't know how to model a
part properly. Seeting out a plan from the start to build your part, anticipating as best you
can changes that may occur in the future and through past experience, a complicated part
can be adjusted from the very 1st feature very successfully. It very much comes down to
the skill of the CAD user and this is one of the areas that makes the difference between
someone who says they can use a 3D CAD package and someone who can actually use it.
If the tree was useless, there would be no posts from users on this forum looking for
workarounds to the problem of saving to an earlier version of the software. Though as I'm
sure you will see if you look that there are many. |
