Brand new interactions and interfaces. 
Easy to use and quick to get started. 
Your description is not clear:
"when i print the shematic the arduino not much to the printed bord..."
Are you asking about the scaling mis match between a printed pdf of the board and the board in the PCB Editor?
Please clarify.
In the meantime, please see:
