You can view and specify the properties of custom component in the custom component Library under the Components Library. You can create a new custom component from scratch or by copying an existing one. After you copy a custom component, change the properties as required and give the new custom component a unique name to distinguish it from the others. HOMER adds this new custom component to your library when you click OK. The new custom component then appears in the list of available custom component types on the custom component page.
