We have already touched on how EasyEDA can support Multi-part Components but how do you create multi-part components?
EasyEDA provides a sub parts facility to do this.
After creating a part, you can right-click the part in the Libraries > SCH Libs > Personal > Created section to pop up the content menu.
Suppose you have created your own symbol for a 74HCT04 hex inverter.
Right Click Add sub part and that will add 74HCT04.1,
Click again to add 74HCT04.2 , up to 74HCT04.6.
Then double click on each sub part in turn to modify the Pin Name and Number attributes.
Easy or what?
