There are quite a few cad software out there and it’s quite costly to buy cad translator software to convert specific cad files to board and board_xy for HP3070. All cad software would be able to output the cad data to ODB++ format files. I wrote scripts to extract ODB++ files to neutral file then use HP3070 cad.format to convert to board and board_xy quite nicely. You can use any software program, but I use Python to do it.
