I am getting ready to create prototypes and after exporting to Gerber format I get the following error from the manufacturer I have chosen:
“This PCB is missing a board outline file (.bor). Board dimensions have been automatically calculated from the available layers. You must provide a valid board outline file prior to verifying part placement or ordering this PCB”
I have absolutely stalled at this point. It must be something simple I’m doing but I can’t understand it. I don’t know where to start to create this file??
