- There, click the Add library icon to open the Library finder dialog. Here select Engineering (the table will be filled only after clicking [Search]) and import the library by clicking [OK].
- The modifications can be adopted by clicking the disk icon at the top left (or using the shortcut key [Ctrl] + [S]).
