DC1763A-A view .pcb files

I'm trying to view the pcb design for the DC1763A-A evaluation board. I'm using the circuit as a reference for our custom baseboard, which has several LTC2194's on it. I'm able to open and view the .pcb file in the design and integration files with Mentor PADS software, but it's a bit cumbersome to use. is there any way to convert/open these design files in another design software, such as altium? Thanks.
