How to create a new footprint

Hi,

 I have downloaded OrCAD 16.5 Demo (all products), but there is not OrCAD Layout. So I don't know how to do it. I have create a new library with only one chip (MPU-6000), but there isn't his pcb footprint, that is 24-pin plcc. And when I create the netlist, the PCB editor doesn't open the file. My schematics is very simple, only has the chip and lines.

Thanks
