* EasyEDA does not suppport hierarchical design. It does support multi-sheet flat schematics. You can draw a section of circuit then copy and paste it in your schematic or you can create a section of circuit then do: `Save As Module...` and then paste that into your schematic. * If you are asking about drawing busses in the schematic then please see: https://easyeda.com/forum/topic/Bus_across_schematics-1BvpGYgys https://easyeda.com/forum/topic/How_do_you_connect_bus_wiring_tool-A93lDxP7p https://easyeda.com/forum/topic/BUS-QuohbtL3l
