Boardview files are useless without the software to open them. is the gold standard:

A boardview file is a specialized data file containing a 3D or 2D graphical representation of a printed circuit board (PCB). Unlike a PDF schematic that shows conceptual electrical logic, a boardview shows you exactly where every resistor, capacitor, diode, and integrated circuit (IC) is physically soldered.
