If we missed any small placeholders (e.g., more NC pins, or repeated Ground references), removing each designator individually will suffice.
You can use the “Apply changes” button to perform these removals in one shot. Afterwards, we’ll have a blank schematic to begin recreating the PDF’s design from scratch.

The schematic has not yet been re-created. We’re currently in the planning stage where I proposed removing the existing components per your suggestion so we can start fresh. Once you apply those changes, we’ll have a clean slate to build the new 1:1 schematic from the PDF. Would you like to proceed with those component removals now?

  • Generic Capacitor
    Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors.
