Hierarchical sheets

Hi Everybody i don’t know how hierarchical work in Kicad.
I am thinking about hierarchical like this.
In reality i am designing a AVR development brd that contains group of sub projects like power supply, dip sockets for various pin count 8,28,40…,EEPROM,ANALOG /DIGITAL TEMP SENSORS…etc. on single brd.
So if i am creating hierarchical sheet for each then using hierarchical labels to connect all sheets together.
I noticed that hierarchical is designed like as DOS tree Root/sub…
Is it working in this method?
Please help
Thanks

Yes, it’s a tree. There is a button in the top row of EEschema where you can navigate the tree.

But how to pass connections one sheet to another sheet.

Using sheet labels and sheet pins, eventually with global labels. Eeschema manual, section 6.

Thanks for help:pensive:
