Library Expert allows you to set the origin anywhere you want. 

The default is Centroid (center of gravity) because that's what the Assembly "Pick & Place" machines use. 

There is no IPC standard for the origin of the footprint. Use common sense for DFA.

Is there a IPC-7351 standard for Footprint Origin? Please help me!

I see the PCB Library Expert Tools always chooses the center of Footprint to set Origin. 

But, I am confused is it the IPCB standard?
