Hi,

Solidworks 2017 64 sp4.0 (update from sp3.0 made no difference)

I have a toolbox in an assembly and every time I open the drawing , the assembly is forced to change so that it requires saving! (video attached)

The toolbox part is "ANSI metric socket head screw ANSI B18.3.1M", but it also happens on the ISO cap head screws.

I use the copied parts option.

I have tried deleting the copied part so that Solidworks rebuilds it, but the error remains.

I know it is related to the toolbox parts as once these parts are removed and I put in my own screw parts, there are no more rebuilds.

My VAR are unable to reproduce this error that is happening on three Solidworks machines.

Has anyone come across this error and fixed it without dumping toolbox in the bin?

Thanks
