I can not use timing belt pulley creation tool in Toolbox,
there is an error and crashes SolidWorks. Is there a way to reload
the database for that selection without affecting other toolbox
areas rather than a full uninstall and re-install of SolidWorks as
recommended by my VAR? I don't want to lose other
customization.
You can do a repair installation with the original install discs. I always run through the copy settings wizard first, though. You never know.
