Open SolidWorks, click Tools > Customize. On the Toolbars tab of the Customize dialog box, select Configurations.
The other method to display the toolbar is to Right click on the Command Manager (Anywhere in the blank area shown by blue box) and select Configurations.
The Configurations toolbar provides a drop-down list of the model's configurations as shown below.
As with other toolbars, we can detach the Configurations toolbar and place it anywhere in the graphics area or on a second monitor.
