You can create a new net in Altium using the following method:
- Access the Menu: In Altium, navigate to the appropriate menu (often found in a PCB editor or similar environment). The specific menu might vary slightly depending on your Altium version and current workspace. Look for an "Edit" or "Project" menu.
- Find the 'Add Net' Command: Within the menu, search for the command labeled "Add Net."
- Open the 'Edit Net' Dialog: Clicking "Add Net" will open the "Edit Net" dialog box.
- Define Net Properties: In the "Edit Net" dialog, you can specify the properties of the new net. This typically includes:
- Net Name: A unique identifier for the net.
- Net Color: A visual aid for distinguishing the net on the PCB layout.
- Net Class: Assigning the net to a specific class for design rule application.
- Other Electrical Properties: Parameters like impedance, voltage, or current requirements, which may be relevant for signal integrity analysis and design rule checks.
- Apply and Close: After defining the net properties, click "OK" or "Apply" to create the new net.
Alternative Method (Direct PCB Editing):
In some cases, Altium allows you to create a new net implicitly by simply placing a component and connecting its pins with wiring. When you connect two previously unconnected pads with a wire, Altium will often create a new net automatically. However, using the "Add Net" command gives you more explicit control over the net's properties.
