# Components Bar

The Components Bar can be displayed by selecting the 'View | Components Bar' menu item. This toolbar is linked to the components palette and allows for the selection of node/pipe elements with which to build a flowsheet model. Similar components are grouped and each component has a unique flowsheet icon. You can customize the components available on this toolbar by selecting the "Down Arrow" on the far right hand side of the Components Bar (see red arrow on Figure 1 below). A new dialog will appear titled "Add or Remove Buttons". Select this option and a new drop-down list of components will appear. Using this drop-down list, you can now select which components you wish to have included or removed from the Components Bar. Figure 1: Components Bar. When a component is selected, the cursor changes accordingly as it moves over the flowsheet. Default values for every component can be user-defined, and different default sets can be saved in different environments. Note: In this User Guide, equipment items in the databases available for building a model are referred to as 'components'; these same items when placed on the flowsheet are referred to as 'elements'.
