component reference point in ultiboard

[jake w]

The default setting for component reference point is the center of PIN 1 of the part. however, for many SMT machines, it reference to the center of the component (not a pin). 

How doＩmodify it without going through every component in the database?

The PIN 1 reference point gets used for positioning the part on your layout. When you export the centroid file, you will see the coordinates for the center of the component.

I prefer to know where that center is so I don't get surprised by oddball SMT coords. This is yet another reason why we maintain our own corporate database of footprints, with the reference point set to the center (or nozzle pick-up point) of the component.
