Hello wangshuguang81_3568726 ,
The newly created component will be available in the 'Default' tab of Component Catalog ( As shown in Picture 1).
Please note that either you have to copy/paste the newly created Library components to your project OR you have to give the dependency of the Library component to your project. ( Right Click on the Project -> Dependency ->Check the new Library ).
Right-click on component symbol background and select Properties (at the bottom of menu). Then in the Catalog Placement type the path for a component. It is a convention to start path with '/Community', following with '/Digital' (or /Analog, or /Communication) but you can make any other names. Remember that the Path must be ended with '/'
