how to make Die bonding IC package?

I have few questions to ask here(I am a new user), much appreciated for your help.

1. How to make Die bonding IC package? I have pad coordiantes. Doese I need use Allegro package design tools? or the general Allegro PCB designer is enough?  Because I found my company floating license is limited for Allegro PCB design.

2. when i import DXF file as my PCB board outline, but I found the size is zoomed out, the actual size is only 1/8, so what's the reason and how to solve it?

Thanks,
