This is an issue I have constantly and am looking for ways to fix it. If I use Toolbox parts in an assembly, and then later move the assembly to another folder or use pack-and-go, often the sizes of those parts will magically change, forcing me to remove them all and replace them. I know I can save the toolbox part under a new name somewhere then use sldsetdocprop to remove the toolbox link, but there must be a simpler, quicker way to do this. I don't mind keeping the link to the toolbox, just as long as I don't open up a part and get 1000 bolts that have resized from 10mm to 30mm for no reason. Does anyone know a solution to this?
