For best results you need to clearly define a PCB profile layer for each job that will be included on your panel. The border will be a single outer line that is connected and joined as one object (if there are slots they also must be closed boundaries). Many times we see a border layer from users but it will consist of many separate line segments (not joined together as one boundary). FAB 3000 requires them to be connected and joined as a single object.
Fortunately FAB 3000 includes two commands to easily detect and create PCB border layers.
Generate Border Selective - Menu: Fabrication / Detect Border (Selective)... Pick a single object on the PCB border and FAB 3000 will create a border profile.
Generate Border Automatic - Menu: Fabrication / Detect Border (Automatic)... This feature will automatically try to detect any border on your PCB.
