I was asked to look into an issue with apart that an engineer designed. The saved part is / K3 D D+ T$ G; S$ Y, o
85megs! The part hasabout 100 features. One of my part with about the same number of , `- w5 j1 h, I- I5 b+ j
features is less then10 megs. Both the engineer and Iare fairly new to SW so I couldn't

This is a problem in Solidworks; two people can design the same identical part and the two 6 J+ v9 U0 p( U! U* k9 `, ~& o

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

First; get rid of all the fluff; studio, lighting, background graphics; all the stuff that has * ]; K/ E5 h% c
nothing to do with the part design. Go to your file options, and check the graphics display 5 d3 {$ T& t. D& g' x

I don't recommend "saving out and bring it back in as dumb geometry." At that point

If you can, do a File, Save As. This usually does the trick. I believe SW saves a lot of history ( A% l# {, o# |2 u& ^
data within each file. When you do a Save As, that history goes bye-bye and you start fresh.5 w5 A4 m$ t% p+ p- |0 I5 |6 y2 @, \

6 l) l. E' W" B5 XI had this same problem with a Solid Works Part a few months ago I tried the save as trick 4 d3 M! c, u" U; T
