Custom Properties in the Task Pane
You can use the Custom Properties tab in the Task Pane to view and enter custom and configuration-specific properties in SOLIDWORKS files.
Data you enter in the Custom Properties tab transfers to the Custom and Configuration Properties tabs in the Properties dialog box.
In assemblies, you can assign properties to multiple parts concurrently. If you select a lightweight component in an assembly, you can view the component's custom properties in the Task Pane without resolving the component. If you edit a value, you must resolve the component to save the change.
