Hello All,
' v* i5 P$ P, S& k8 R' l3 s+ y p) o5 }( B% D1 L7 ]
I was asked to look into an issue with apart that an engineer designed. The saved part is
3 b2 X& M( j- ?# l% ]85megs! The part hasabout 100 features. One of my part with about the same number of ) f2 J+ R; M u; g7 A9 q. B
features is less then10 megs. Both the engineer and Iare fairly new to SW so I couldn't
2 z" ]: }! }4 x, V2 x% Pfigure out what the problem was.All features weremade from simple extrusions, cuts,
3 A* l: h: _, I6 L+ q0 Qpatterns, chamfers, rounds. No complicated surfaces and not drafted yet. I did notice that
/ d' \ q: D1 D8 {: e" Va lot of the extrusion and cut features were created as thins.3 {6 M$ t+ M' a! L/ c5 I6 ]
( c: k3 k! O Y. j7 X& h3 [
I would hate to have to recreate the part.

This is a problem in Solidworks; two people can design the same identical part and the two $ u+ p; k# X- Z
part file sizes can vary widely. If one made lots of changes; rebuilt his model numerous ! P( P; H ]) Z; T% }& H7 I# ]
times withmoved features in the tree; added and removed constraints, modified scetches, 6 X" F6 z9 y' G
etc, etc..., that file will grow and grow and grow.

I have noticed that similar files have exhibited a size reduction when opened and saved in

If you can, do a File, Save As. This usually does the trick. I believe SW saves a lot of history

I had this same problem with a Solid Works Part a few months ago I tried the save as trick . E# e* W; g7 A, G
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.- }* A, r+ b0 T6 a; |0 ~' W

If the tree was useless, there would be no posts from users on this forum looking for
