I'm using toolbox components on SolidWorks 2015 SP5.0. Each time I pick up a new component from the Tollbox, SW update the toolbox part component adding a new configuration. Now I'm trying to add custom properties on components using the Toolbox configuration tool. It works fine for the new parts but it doesn't change the properties if a part (configuration) already exists. So it's not possible to change the properties on parts already created unless modifying one by one the properties of each configuration in the read-only part model in the toolbox folder. Am I doing something wrong? Is there a way to make the Toolbox configurator to update the existing configuration been created?
