If you are experiencing slowness or sluggishness while working on SolidWorks models and you open your files over a network, it is worthwhile to check to see if the network is causing at least some of the problems. 

To test whether performance issues are related to opening files over a network, place an assembly and its referenced files on your local hard drive and work on the assembly from there.

Procedure:

1. If you have the assembly open, go to File>Pack and Go …
2. Alternatively, in Windows Explorer, browse to the assembly, right click, click on SolidWorks, then Pack and Go …
3. In the Pack and Go window, in Save to folder – browse to a folder on your C:\ drive and place in a temporary folder.  In this example I created a new folder just to test this assembly.
4. Add a prefix or a suffix to change the filenames of all of the models so these won’t be confused with your regular models.
5. Click Save

 

 Open this assembly and work with it for a while and see if you notice an improvement in performance.
