    NEED HELP
    I HAVE THIS DESIGN PROECT,AND I NEED TO TEST THEM WITH DESIGN RULLES CHECK,BUT I HAVE ERORR
    WARNING(ORCAP-1600): Net has fewer than two connections N02725 ,I DONT KNOW, I USE THIS PROGRAM 2 DAY BUT I NEED TO VERIFICY THIS SCHEM ,PLEASE WHO CAN TO HELP ME,(( I SUBSCRIBE MY DESIGN,AND WHO CAN MODIFICY THEM FOR THE GOOD DESIGN RULLES CHECK( SORY FOR MY ENGLISH .

    Is that schematic supposed to be a joke?

    What is your project about?
    What do you need to design?

    What do you want the circuits to achieve?

    I'm guessing the OP did his best and is expecting the "Design Rules Check" to guide him to an optimized design.

    YOU DON'T NEED TO YELL! TYPING IN ALL CAPS IS COMPLETELY UNNECESSARY!

    That schematic is a mess, and I'm seeing missing wires. That's why the ERC doesn't like it.

    A "Design Rule Check" or simply "DRC" is a schematic capture term for some simple tests your program can do for you automatically, and far more accurately than you ever could.

    "fewer than two connections" simply means you have a part not connected to anything. There should be some method of identifying exactly what part is causing this or other errors.

    I did notice your relay or switch contacts have no wires attached. If that is truly your intent then look for the "no connect" tool and designate these pins as not connected. That clears the error.

    Note a clear (no errors) DRC does not mean your circuit will work. It just means it was drawn correctly.

    Actually, to be more specific, a DRC is used for checking for errors on a PCB design. The schematic tool is the ERC, which stands for Electrical Rules Check (rather than Design Rules Check).
