Hi, I realize that replying to a 20 year old post might be a long shot..
After my colleague opened my network-stored assembly on a fresh install of SolidWorks 2020 SP5.0, some parts have mysteriously changed size. These are ISO parts that were taken from the toolbox.
When I right-click on the components, the "Edit Toolbox Components" option is missing.
The solution presented in this link did unfortunately not work for me. me

I can't seem to change the size of these ISO components, unless I treat them as custom parts. I'd like to avoid this as I'm not quite ready to redesign all the gears and screws simply imported from the ISO library.
