( }# \' \- R% j2 d4 T) y# N1 }# E+ ]6 nI was asked to look into an issue with apart that an engineer designed. The saved part is

figure out what the problem was.All features weremade from simple extrusions, cuts, & X [' S, g: {: v4 r' m) M3 p
patterns, chamfers, rounds. No complicated surfaces and not drafted yet. I did notice that

This is a problem in Solidworks; two people can design the same identical part and the two 6 ~% P+ |3 w3 z0 d6 u; W
part file sizes can vary widely. If one made lots of changes; rebuilt his model numerous

Thanks for shedding some light on the problem. We had a design review and quite a few

Yes, absolutely you need the feature tree.+ X* M9 \2 |) w
; S+ D: D6 n; M
If its a complicated part, the feature tree is worthless if you don't know how to model a

can changes that may occur in the future and through past experience, a complicated part & P& P0 _( U0 X, v
can be adjusted from the very 1st feature very successfully. It very much comes down to

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