How can I add a custom board to the PCB wizard options?

If you wish to regularly use a PCB board outline in new projects, save the PCB design file containing only the board outline. This file can be moved or copied using the Windows file manager into the DesignSpark PCB "Technology" folder as in the following example.

Now, when translating from the schematic to the PCB or creating a new PCB, at the following step in the Wizard "Define your board outline" you can select your board outline.

When you complete the wizard, your custom board outline will be ready to use. It will be available in the drop-down menu next time you use the PCB creation wizard.
