I use toolbox parts routinely in my assemblies and assign my firm’s component variety as a custom assets in the assets tables. On several situations the toolbox seems to have dropped the component variety for no clear motive. I know that the toolbox component was saved with the custom assets, and I know that in most cases I experienced opened that assembly (and assembly drawing) just after earning the alter and the alter was however. At some afterwards time, when the assembly was opened, the custom assets (component variety) was no lengthier there. I am utilizing SolidWorks 2017 and the toolbox is on my challenging drive, I do not use a PDM (I am the only person).
