From the Customize Hardware page, Toolbox administrators can add custom properties to Toolbox and apply them to individual components or to all components in a standard.
You can create text properties, list properties, or material properties.
Once you create a property, you can apply it to an entire standard, category, or type, or an individual component. For text configuration-specific properties, you can type values directly in the configurations table. The custom properties you assign appear in the component PropertyManager. When using the component, Toolbox users can enter custom property values in the PropertyManager.
To apply a custom property to a standard, select the standard in the left pane and select the property in the right pane.
You can use the Property Tab Builder utility to assign custom properties to SOLIDWORKS files. For more information, see SOLIDWORKS Help: Property Tab Builder Overview.
