Hi somulu!
You use S-EDIT for your schematic, LEDIT is for the layout. To transfer your schematic to a layout, you need to use SDL. just go to File>Export>SPICE
In the SPICE dialog, you'll see a list at the bottom, type "SDL". then export your SDL SPICE netlist that resulted by clicking OK.
In LEDIT go to Tools > SDL, then import that netlist.
LEDIT will then instance the devices in the schematic for you, you can now connect them either manually or use Auto-Routing.
Auto-Routing will route everything for you automatically, all you have to do it set up the routing from Tools.
Good luck!
