3. Right-click on the project name in the “Projects” panel and select “New” > “Schematic” to create a new schematic file.

Schematic Design

1. In the schematic editor, use the “Add” tool to place components from the libraries onto the schematic canvas.

2. Connect the components using the “Net” tool to create electrical connections.

3. Use the “Name” tool to assign names to nets and components for easier identification.

4. Perform a electrical rule check (ERC) to identify any errors or warnings in the schematic design.

PCB Layout Design

1. Once the schematic design is complete, switch to the PCB layout editor by clicking on the “Board” button in the schematic editor.

2. Use the “Move” tool to position components on the PCB canvas according to your design requirements.

3. Define the board outline using the “Wire” tool and set the appropriate board dimensions.

4. Route the connections between components using the “Route” tool, following the design rules specified in the DRC.

5. Add copper pours, vias, and other PCB features as needed.

6. Perform a design rule check (DRC) to ensure that the PCB layout adheres to the specified design rules.

Generating Manufacturing Files

1. Once the PCB layout is complete, generate the necessary manufacturing files by clicking on “File” > “CAM Processor”.

2. Select the desired output formats (e.g., Gerber, drill files) and configure the output settings.

3. Click on “Process Job” to generate the manufacturing files, which can be sent to a PCB Fabrication house for production.
