Hi @liquid_words,


I hope you're doing well. In Fusion 360, on the schematic right clicking on any component you'll have the option to Invoke the components. You'll also find the INVOKE command in the Modify menu.


In the first picture, those are inverted and clock pins. In the symbol editor, you'll see this in the pin properties in the function combobox. These are usually only used when dealing with digital logic circuits.


Let me know if you have any other questions.


Best Regards,
