Pack and Go feature in SolidWorks
This feature is used to collect those all parts in one Assembly file. Sometime we don't put those all parts that compose a SolidWorks assembly system in the same folder.
When we want to share the assembly file or open the assembly file in different computer, we have to find them and collect them (the parts) in one folder. It will take times and efforts. Pack and Go Feature, will help us to collect those all parts that arrange an assembly file from many places.
