Trying to generate a fabrication drawing.

Thanks for your question.  A border must be a closed boundary.  My guess is that your border layer may consist of individual traces. 

FAB 3000 will prompt a message asking to automatically generate a border layer with closed boundaries.  Select Yes and your border layer will be correctly constructed. 

Note:  You may also manually perform this task using the command Generate Border Layer (menu: Fabrication / Generate Missing Layers / Border).
